Controlling Measurement Samples

Varying the Voltage or Current Sampling Rate

You can vary both the number of data points in a measurement sample, as well as the time between samples. This is illustrated in Figure 3-5.

SENS:SWE:TINT <time>

SENS:SWE:POIN <# of points>

TRIG:ACQ:COUN:CURR <# of sweeps>

Figure 3-5. Sense Commands Used to Vary the Sampling Rate

At *RST, the output voltage or current sampling rate is 15.6 microseconds. This means that it takes about

32 milliseconds to fill up 2048 data points in the data buffer. You can vary this data sampling rate with:

SENSe:SWEep:TINTerval <sample_period>

SENSe:SWEep:POINts <points>

For example, to set the time interval to 46.8 microseconds per sample with 1500 samples, use SENSe:SWEep:TINTerval 46.8E-6;POINts 1500.

Multiple Measurements (Agilent 66312A, 66332A Only)

The instrument also has the ability to set up several acquisition triggers in succession and average the results from each acquisition in the returned measurement. To set up the trigger system for a number of sequential aquisitions use:

TRIGger:ACQuire:COUNt:CURRent <number> or

TRIGger:ACQuire:COUNt:VOLTage <number>

With this setup, the instrument performs each acquisition sequentially, storing the digitized readings in the internal measurement buffer. It is only necessary to initialize the measurement once at the start; after each completed aquisition the instrument will wait for the next valid trigger condition to start another. The results returned by MEASure or FETCh will be the average of the total data acquired.

NOTE: The total number of data points cannot exceed 4096. This means that the product of the trigger count multiplied by the sweep points cannot exceed 4096; otherwise an error will occur.
