LPT library function reference
4200A-901-01 Rev. C / February 2017 13-5
Command Description
setauto (on page 13-85)
Re-enables autoranging and cancels any previous rangeX command for the
specified instrument.
ssmeasX (on page 13-
86)
Makes a series of readings until the change (delta) between readings is within a
specified percentage.
sweepX (on page 13-88)
Generates a ramp consisting of ascending or descending voltages or currents. The
sweep consists of a sequence of steps, each with a user-specified duration.
PGU (pulse only) and PMU (pulse and measure) commands
In the LPT commands, the pulse-only module (4220-PGU) is referred to as VPU1, VPU2, and so on.
The pulse-measure module (4225-PMU) is referred to as PMU1, PMU2, and so on. The 4210-CVU is
referred to as CVU1, CVU2, and so on.
Note that the 4225-PMU and 4220-PGU support the PG2 commands.
Command Description
dev_abort (on page 13-
92)
PGU, PMU. Programmatically ends a test from within the user module (aborts a
test) that was started with the pulse_exec command.
PostDataDoubleBuffer
(on page 13-94)
PMU. Posts PMU data retrieved from the buffer into the Clarius Analyze sheet (large
data sets).
pulse_chan_status (on
page 13-96)
PMU. Used to determine how many readings are stored in the data buffer.
pulse_conncomp (on
page 13-96)
PMU. Enables or disables connection compensation.
pulse_exec (on page 13-
98)
PGU, PMU. Used to validate the test configuration and start test execution.
pulse_exec_status (on
page 13-100)
PGU, PMU. Used to determine if a test is running or completed.
pulse_fetch (on page 13-
101)
PMU. Retrieves enabled test data and temporarily stores it in the data buffer.
pulse_limits (on page 13-
107)
PMU. Sets measured voltage and current thresholds at the DUT and sets the power
threshold for each channel.
pulse_meas_sm (on
page 13-108)
PMU. Configures spot mean measurements.
pulse_meas_timing (on
page 13-109)
PMU. Sets the measurement windows.
pulse_meas_wfm (on
page 13-111)
PMU. Configures waveform measurements.
pulse_measrt (on page
13-112)
PMU. Returns pulse source and measure data in pseudo real-time.
pulse_ranges (on page
13-113)
PGU, PMU. Sets the voltage pulse range and voltage/current measure ranges.
pulse_remove (on page
13-115)
PGU, PMU. Removes a pulse channel from the test.
pulse_sample_rate (on
page 13-116)
PMU. Sets the measurement sample rate.
pulse_source_timing (on
page 13-116)
PGU, PMU. Sets the pulse period, pulse width, rise time, fall time, and delay time.
pulse_step_linear (on
page 13-118)
PGU, PMU. Configures the pulse stepping type.
pulse_sweep_linear (on
page 13-120)
PGU, PMU. Configures the pulse sweeping type.
