init_measurement() → None

Change the state of the triggering system from “idle” to “wait-for-trigger”, and clear the previous set of measurements from reading memory.

This method is an “overlapped” command. This means that after executing it, you can send other commands that do not affect the measurements.

Storing measurements in reading memory with this method is faster than sending measurements to the instrument’s output buffer using read method (“READ?” command) (provided you do not fetch, “FETCh?” command, until done).

reset() → None

Reset the instrument to factory defaults. Also updates the snapshot to reflect the new (default) values of parameters.

abort_measurement() → None

Abort a measurement in progress, returning the instrument to the trigger idle state.

fetch() → ndarray

Waits for measurements to complete and copies all available measurements to the instrument’s output buffer. The readings remain in reading memory.

This query does not erase measurements from the reading memory. You can call this method multiple times to retrieve the same data.

Returns:

a 1D numpy array of all measured values that are currently in the reading memory

read() → ndarray

Starts a new set of measurements, waits for all measurements to complete, and transfers all available measurements.

This method is similar to calling init_measurement() followed immediately by fetch().

Returns:

a 1D numpy array of all measured values

autorange_once() → None

Performs immediate autorange and then turns autoranging off.

The value of the range parameter is also updated.

increase_range(range_value: float | None = None, increase_by: int = 1) → None

Increases the voltage range by a certain amount with default of 1. If limit is reached, the max range is used.

Parameters:

• range_value – The desired voltage range needed. Expressed by power of 10^x range from -3 to 10

• increase_by – How much to increase range by, default behavior is by a step of one.

decrease_range(range_value: float | None = None, decrease_by: int = -1) → None

Decrease the voltage range by a certain amount with default of -1. If limit is reached, the min range is used.

Parameters:

• range_value – The desired voltage range needed. Expressed by power of 10^x range from -3 to 10

• decrease_by – How much to decrease range by, default behavior is by a step of one.

self_calibration(slot: SlotNr | int | None = None) → CALResponse

Performs the self calibration of the specified module (SMU) and returns the result. Failed modules are disabled, and can only be enabled by the RCV command.

Calibration takes about 30 seconds (the visa timeout for it is controlled by calibration_time_out attribute).

Execution Conditions: No SMU may be in the high voltage state (forcing more than ±42 V, or voltage compliance set to more than ±42 V). Before starting the calibration, open the measurement terminals.

Parameters:

slot – Slot number of the slot that installs the module to perform the self-calibration. For Ex: constants.SlotNr.ALL, MAINFRAME, SLOT01, SLOT02 …SLOT10 If not specified, the calibration is performed for all the modules and the mainframe.

error_message(mode: Mode | int | None = None) → str

This method reads one error code from the head of the error queue and removes that code from the queue. The read error is returned as the response of this method.

Parameters:

mode – If no valued passed returns both the error value and the error message. See constants.ERRX.Mode for possible arguments.

Returns:

In the default case response message contains an error message and a custom message containing additional information such as the slot number. They are separated by a semicolon (;). For example, if the error 305 occurs on the slot 1, this method returns the following response. 305,”Excess current in HPSMU.; SLOT1” If no error occurred, this command returns 0,”No Error.”

This method clears the error message stored in buffer when the error_message command is executed.

clear_timer_count(chnum: int | None = None) → None

This command clears the timer count. This command is effective for all measurement modes, regardless of the TSC setting. This command is not effective for the 4 byte binary data output format (FMT3 and FMT4).

Parameters:

chnum – SMU or MFCMU channel number. Integer expression. 1 to 10. See Table 4-1 on page 16 of 2016 manual. If chnum is specified, this command clears the timer count once at the source output start by the DV, DI, or DCV command for the specified channel. The channel output switch of the specified channel must be ON when the timer count is cleared.

If chnum is not specified, this command clears the timer count immediately,

set_measurement_mode(mode: Mode | int, channels: Sequence[ChNr | int] | None = None) → None

This method specifies the measurement mode and the channels used for measurements. This method must be entered to specify the measurement mode. For the high speed spot measurements, do not use this method. NOTE Order of the channels are important. The SMU which is setup to run the sweep goes first.

perform(corr)	Perform Open/Short/Load corrections using this method.
perform_and_enable(corr)	Perform the correction AND enable it.

enable(corr: CalibrationType) → None

This command enables the open/short/load correction. Before enabling a correction, perform the corresponding correction data measurement by using the perform().

Parameters:

corr – Depending on the the correction you want to perform, set this to OPEN, SHORT or LOAD. For ex: In case of open correction corr = constants.CalibrationType.OPEN.

disable(corr: CalibrationType) → None

This command disables an open/short/load correction.

Parameters:

corr – Correction type as in constants.CalibrationType

is_enabled(corr: CalibrationType) → Response

Query instrument to see if a correction of the given type is enabled.

Parameters:

corr – Correction type as in constants.CalibrationType

set_reference_values(corr: CalibrationType, mode: Mode, primary: float, secondary: float) → None

This command disables the open/short/load correction function and defines the calibration value or the reference value of the open/short/load standard. Any previously measured correction data will be invalid after calling this method.

Parameters:

• corr – Correction mode from constants.CalibrationType. OPEN for Open correction SHORT for Short correction LOAD for Load correction.

• mode – Measurement mode from constants.DCORR.Mode Cp-G (for open correction) Ls-Rs (for short or load correction).

• primary – Primary reference value of the standard. Cp value for the open standard. in F. Ls value for the short or load standard. in H.

• secondary – Secondary reference value of the standard. G value for the open standard. in S. Rs value for the short or load standard. in Ω.

get_reference_values(corr: CalibrationType) → str

This command returns the calibration values or the reference values of the open/short/load standard.

Parameters:

corr – Correction mode from constants.CalibrationType. OPEN for Open correction SHORT for Short correction LOAD for Load correction.

Returns:

A human-readable string with the correction mode constants.DCORR.Mode and its reference values

perform(corr: CalibrationType) → Response

Perform Open/Short/Load corrections using this method. Refer to the example notebook to understand how each of the corrections are performed.

Before executing this method, set the oscillator level of the MFCMU.

If you use the correction standard, execute the set_reference_values() method (corresponds to the DCORR command) before this method because the calibration value or the reference value of the standard must be defined before performing the correction.

Parameters:

corr – Depending on the the correction you want to perform, set this to OPEN, SHORT or LOAD. For ex: In case of open correction corr = constants.CalibrationType.OPEN.

Returns:

Status of correction data measurement in the form of constants.CORR.Response

perform_and_enable(corr: CalibrationType) → str

timing_parameters(h_bias: float, interval: float, number: int, h_base: float | None = None) → None

This command sets the timing parameters of the sampling measurement mode (MM.Mode.SAMPLING, 10).

Refer to the programming guide for more information about the MT command, especially for notes on sampling operation and about setting interval < 0.002 s.

Parameters:

• h_bias – Time since the bias value output until the first sampling point. Numeric expression. in seconds. 0 (initial setting) to 655.35 s, resolution 0.01 s. The following values are also available for interval < 0.002 s. |h_bias| will be the time since the sampling start until the bias value output. -0.09 to -0.0001 s, resolution 0.0001 s.

• interval – Interval of the sampling. Numeric expression, 0.0001 to 65.535, in seconds. Initial value is 0.002. Resolution is 0.001 at interval < 0.002. Linear sampling of interval < 0.002 in 0.00001 resolution is available only when the following formula is satisfied. interval >= 0.0001 + 0.00002 * (number of measurement channels-1)

• number – Number of samples. Integer expression. 1 to the following value. Initial value is 1000. For the linear sampling: 100001 / (number of measurement channels). For the log sampling: 1 + (number of data for 11 decades)

set_average_samples_for_high_speed_adc(number: int = 1, mode: Mode = Mode.AUTO) → None

This command sets the number of averaging samples of the high-speed ADC (A/D converter). This command is not effective for the high-resolution ADC. Also, this command is not effective for the measurements using pulse.

Parameters:

• number – 1 to 1023, or -1 to -100. Initial setting is 1. For positive number input, this value specifies the number of samples depended on the mode value. For negative number input, this parameter specifies the number of power line cycles (PLC) for one point measurement. The Keysight B1500 gets 128 samples in 1 PLC. If number is negative it ignores the mode argument.

• mode – Averaging mode. Integer expression. This parameter is meaningless for negative number. constants.AV.Mode.AUTO: Auto mode (default setting). Number of samples = number x initial number. constants.AV.Mode.MANUAL: Manual mode. Number of samples = number

• v_end – ending voltage of staircase sweep

• n_steps – number of measurement points (uniformly distributed between v_start and v_end)

• post_sweep_voltage_val – voltage to hold at end of sweep (i.e. start or end val). Sweep chan will also output this voltage if an abort condition is encountered during the sweep

• av_coef – coefficient to use for av command to set ADC averaging. Negative value implies NPLC mode with absolute value of av_coeff the NPLC setting to use. Positive value implies auto mode and must be set to >= 4

• enable_filter – turn SMU filter on or off

• v_src_range – range setting to use for voltage source

• i_comp – current compliance level

• i_meas_range – current measurement range

• hold_time – time (in s) to wait before starting very first measurement in sweep

• delay – time (in s) after starting to force a step output and before starting a step measurement

• step_delay – time (in s) after starting a step measurement before next step in staircase. If step_delay is < measurement time, B1500 waits until measurement complete and then forces the next step value.

• measure_delay – time (in s) after receiving a start step measurement trigger and before starting a step measurement

• abort_enabled – Enbale abort

• sweep_mode – Linear, log, linear-2-way or log-2-way

phase_compensation(mode: Mode | int | None = None) → Response

Performs the MFCMU phase compensation, sets the compensation data to the KeysightB1500, and returns the execution results.

This method resets the MFCMU. Before executing this method, set the phase compensation mode to manual by using phase_compensation_mode parameter, and open the measurement terminals at the end of the device side. The execution of this method will take about 30 seconds (the visa timeout for it is controlled by phase_compensation_timeout attribute). The compensation data is cleared by turning the KeysightB1500 off.

Parameters:

mode –

Command operation mode constants.ADJQuery.Mode.

• 0: Use the last phase compensation data without measurement.

• 1: Perform the phase compensation data measurement.

If the mode parameter is not set, mode=1 is assumed by the instrument.

Returns:

class qcodes.instrument_drivers.Keysight.KeysightErrorQueueMixin

Bases: object

Mixin class for visa instruments that happen to implement an error queue.

It is meant to work ONLY with drivers for Keysight instruments (which inherit from VisaInstrument class).

Methods:

error()	Return the first error message in the queue.
flush_error_queue([verbose])	Clear the instrument error queue, and prints it.

error() → tuple[int, str]

Return the first error message in the queue. It also clears it from the error queue.

Up to 20 errors can be stored in the instrument’s error queue. Error retrieval is first-in-first-out (FIFO).

If more than 20 errors have occurred, the most recent error stored in the queue is replaced with -350,”Queue overflow”. No additional errors are stored until you remove errors from the queue. If no errors have occurred when you read the error queue, the instrument responds with +0,”No error”.

Returns:

The error code and the error message.

flush_error_queue(verbose: bool = True) → None

Override this if your instrument does not support *IDN? or returns a nonstandard IDN string. This string is supposed to be a comma-separated list of vendor, model, serial, and firmware, but semicolon and colon are also common separators so we accept them here as well.

Returns:

A dict containing vendor, model, serial, and firmware.
