QCoDeS Example with Keysight 33500B

from qcodes.instrument_drivers.Keysight import Keysight33522B

ks = Keysight33522B("ks", "TCPIP0::K-33522B-00256::inst0::INSTR")

Connected to: Agilent Technologies 33522B (serial:MY57800256, firmware:5.00-1.19-2.00-58-00) in 1.85s

Basic usage

# SET up a sawtooth
ks.ch1.function_type("RAMP")
ks.ch1.ramp_symmetry(100)
ks.ch1.amplitude_unit("VPP")
ks.ch1.amplitude(1)
ks.ch1.offset(0)
ks.ch1.frequency(2e3)
ks.sync.source(1)

# Start it
ks.sync.output("ON")
ks.ch1.output("ON")

ks.ch1.frequency(1e3)

# stop it
ks.sync.output("OFF")
ks.ch1.output("OFF")

Using burst mode

In burst mode, the instrument starts running a task (e.g. a waveform generation) upon receiving a trigger

# TRIGGERING

# Can be 'EXT' (external), 'IMM' (immediate, internal),
# 'BUS' (software trigger), 'TIM' (timed)
ks.ch1.trigger_source("EXT")

ks.ch1.trigger_count(1)
ks.ch1.trigger_delay(0)  # seconds

# for external triggering, a slope should be specified
ks.ch1.trigger_slope("POS")

# For timed triggering, the time between each trigger should be set
ks.ch1.trigger_timer(50e-3)

# BURSTING

ks.ch1.burst_state("ON")
ks.ch1.burst_mode("N Cycle")  # Can be 'N Cycle' or 'Gated'

# when in 'N Cycle' mode, the following options are available
ks.ch1.burst_ncycles(1)  # Can be 1, 2, 3,... , 'MIN', 'MAX', or 'INF'
ks.ch1.burst_phase(180)  # the starting phase (degrees)

# If in 'Gated' mode, the following should be specified
ks.ch1.burst_polarity("NORM")  # Can be 'NORM' or 'INV'

Error handling

# The instrument has an error queue of length up to 20 messages.
# The queue message retrieval is first-in-first-out

# The first (i.e. oldest) error message in the queue can be gotten (and thereby removed from the queue)
ks.error()

(0, 'No error')

# The entire queue can be flushed out

# generate a few errors
for ii in range(3):
    ks.write("gimme an error!")

ks.flush_error_queue()
