6 – Making Enhanced Front Panel Measurements

The following figure illustrates the enhanced measurement capabilities of Agilent Models 66311B/D and 66309B/D for measuring output waveforms. These include peak (max), minimum, high level, and low level measurements as illustrated in the following figure. Rms and dc voltages are calculated from the number of points in the measurement window.

V or A MAX

46.8 microsecond sampling rate

V or A HIGH

NOTE:

V or A LOW

V or A MIN

Measurement samples may not

coincide with the actual maximum

or minimum point of the waveform.

Figure 5-5. Default Front Panel Measurement Parameters

All models except the Agilent 66111A have two current measurement ranges that can be selected in the Input menu. A high current range is available for measuring output currents of up to 7 amperes. A low current range is available for improved resolution when measuring output currents below 20 milliamperes. The low current measurement range is accurate to 0.1% of the reading ±2.5 microamperes. When the current Range is set to AUTO, the unit automatically selects the range with the best measurement resolution.

NOTE: In the LOW current measurement range, the current detector is fixed at DC. With the current detector in dc, accurate current measurements cannot be made on waveforms with frequency contents over 1 kilohertz.
