Driver Functions
agb1500_setSample
period Pulse period (in seconds). 0.005 to 5.0 s. 0.1 ms resolution.
• period ≥ width +2 msec (for width ≤ 100 ms)
• period ≥ width +10 msec (for width > 100 ms)
If you set period=0, the B1500 automatically sets the pulse
period to 5 msec (for width ≤ 3 ms), width +2 msec (for 3 ms <
width ≤ 100 ms), or width +10 msec (for width > 100 ms).
comp Compliance value (in V or A). It must be voltage for the current
sweep source, or current for the voltage sweep source.
Compliance polarity is automatically set to the same polarity as
the output value, regardless of the specified comp polarity. The
compliance polarity is positive if the output value is 0.
agb1500_setSample
This function sets the timing parameters of the sampling measurement.
To set the synchronous constant voltage/current source for the sampling
measurement, execute the agb1500_addSampleSyncIv function. To set the linear or
logarithmic sampling mode, execute the agb1500_setSampleMode function. To set
the automatic measurement abort function and the post measurement output value,
execute the agb1500_stopMode function. To define the measurement channels and
start the measurement, execute the agb1500_sampleIv function.
Syntax ViStatus _VI_FUNC agb1500_setSample(ViSession vi, ViReal64 bias_hold,
ViReal64 base_hold, ViReal64 interval, ViInt32 point);
Parameters vi Instrument handle returned from agb1500_init( ).
bias_hold 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.
|bias_hold| will be the time since the sampling start until the
bias value output.
-0.09 to -0.0001 s, resolution 0.0001 s.
base_hold Hold time of the base value output until the bias value output.
Numeric expression. in seconds. 0 (initial setting) to 655.35 s,
resolution 0.01 s.
