3 - Programming the DC Source

This results in a data acquisition time of 32 milliseconds. Adding a command processing overhead of about 20 milliseconds results in a total measurement time of about 50 milliseconds per measurement sample.

Ripple rejection is a function of the number of cycles of the ripple frequency contained in the acquisition window. More cycles in the aquisition window results in better ripple rejection. If you increase the time interval for each measurement to 45 microseconds for example, this results in 5.53 cycles in the acquisition window at 60 Hz, for a ripple rejection of about 70 dB.

Note that the speed of the measurement can be increased by reducing the number of sample points. For example, the commands

SENSe:SWEep:TINTerval 15E-6

SENSe:SWEep:POINts 1024

speeds up the acquisition period to 16 milliseconds; however, the tradeoff is reduced measurement accuracy.

RMS Measurements (Agilent 66312A, 66332A Only)

To read the rms content of a voltage or current waveform, use:

MEASure:VOLTage:ACDC? or

MEASure:CURRent:ACDC?

This returns the total rms measurement, including the dc portion.

Making rms measurements on ac waveforms for which a non-integral number of cycles of data has been acquired may result in measurement errors due to the last partial cycle of acquired data. The instrument reduces this error by using a Hanning window function when making the measurement.

Minimum and Maximum Measurements (Agilent 66312A, 66332A Only)

To measure the maximum or minimum voltage or current of a pulse or ac waveform, use:

MEASure:VOLTage:MAXimum?

MEASure:VOLTage:MINimum?

MEASure:CURRent:MAXimum?

MEASure:CURRent:MINimum?

Current Ranges

The dc source has two current measurement ranges. The command that controls the ranges is:

SENSe:CURRent:RANGe MIN MAX

When the range is set to MIN, the maximum current that can be measured is 20 milliamperes.

Returning Measurement Data From the Data Buffer (Agilent 66312A, 66332A Only)

The MEASure and FETCh queries can also return all data values of the instantaneous voltage or current buffer. The commands are:

MEASure:ARRay:CURRent?

MEASure:ARRay:VOLTage?
