Agb1500_Setsamplemode - Agilent Technologies B1500A User Manual

Syntax
Parameters
3. Another bias_hold seconds later, the measurement channels start measurement
for the first sampling point. The measurement channels perform the
measurement in series by the order set to the agb1500_sampleIv function.
4. After that, the following operation is repeated with the specified time interval.
• Measurement channels start measurement if they are ready to measure.
• Measurement channels keep the condition if they are busy.
This operation is repeated until the number of measurement result data reaches
to the specified point of measurement data.
For the linear sampling with interval < 2 ms, if the total measurement time runs
over the specified time interval × point, the sampling measurement will be
stopped even if the number of measurement result data is less than the specified
point.
For the log sampling, the B1500A holds only the data that can be plotted on the
log scale in the same distance as close as possible. Only the held data is counted
in the number of measurement result data.
5. The sampling measurement is completed. And the agb1500_addSampleSyncIv
output channel forces the base or bias value specified by the agb1500_stopMode
function. The agb1500_force output channel keeps its output.
The index data and the time data returned with the measurement data will be as
shown in the following formula. However, long measurement or busy status may
cause unexpected time data.
time data = t + bias_hold + ( index data -1) × interval
Where, t is the time of the sampling measurement time origin, and is the time when
the output value is changed from base to bias.

agb1500_setSampleMode

This function sets the sampling mode, linear or logarithmic. For the logarithmic
sampling, this function also specify the number of measurement data to be returned.
If you do not execute this function, the last sampling mode is effective. Initialization
such as the agb1500_reset function sets the linear sampling mode.
ViStatus _VI_FUNC agb1500_setSampleMode(ViSession vi, ViInt32 mode);
