Programming Examples - 3Controlling Measurement SamplesVarying the Sampling RateYou can vary both the number of data points in a measurement sample, as well as the time betweensamples. You can also specify a delay from the trigger to the start of the measurement. This is illustratedin the following figure.SENS:SWE:TINT SENS:SWE:POIN TRIG:SEQ2:COUN Trigger1 Trigger2 Trigger4Trigger3SENS:SWE:OFFS Figure 3-2. Sense Commands Used to Vary the Sampling RateAt power-on, the input voltage and current sampling rate is 10 microseconds. This means that, notaccounting for the command processing overhead, it takes about 41 milliseconds to fill up 4096 datapoints in the data buffer. You can vary this data sampling rate with:SENSe:SWEep:TINTerval SENSe:SWEep:POINts For example, to set the time interval to 50 microseconds per sample with 500 samples, use:SENSe:SWEep:TINTerval 50E-6;POINts 500.Measurement DelayYou can delay the start of a measurement in relation to the trigger. This is useful if you do not want tostart taking measurements at the beginning of an input transient or list step during the time that the inputvoltage or current is still slewing or settling into its programmed value. To offset the measurement fromthe beginning of the input transient or list step, use:SENSe:SWEep:OFFSet 10E-3In this example, the measurement occurs 10 milliseconds after the start of the trigger. The offset can beset to a negative value, but this number cannot exceed the TRIGger:DELay value.Multiple MeasurementsThe electronic load also has the ability to set up several acquisition triggers in succession andconcatenate the results from each acquisition in the measurement buffer. This is useful for makingmeasurements from lists. To set up the trigger system for a number of sequential acquisitions use:TRIGger:SEQuence2:COUNt 37
