66xxA and E36xxA: P-P Voltage Noise Versus RMS Noise
Both Vp-p and Vrms are measures for the unwanted AC components of a DC power supply output. Peak-to-peak noise is measured from the maximum positive point on the waveform to the most negative voltage point.

FAQ 2008-09-22

Why doesn't my System Power Supply accept commands over the GPIB?
If you are getting either error 11 or error 113 when you try to send GPIB commands to your system supply, it may be that you are using the wrong command language.

FAQ 2008-07-29

Do I need to order option 054 (High Speed Test Extensions) for the N6751A, N6752A, and N6754A High Performance DC Power Modules, when I plan on usi...
Option 054 is not required when the DC Power Module will be used in a DC Power Analyzer.

FAQ 2007-11-04

How can I offset the voltage drop caused by long cable lengths from my dc power supply to the device under test (DUT)?
Normally, Keysight power supplies are delivered configured to deliver their full specs at the output terminals. In some application, where long lead lengths to the DUT are unavoidable, the regulation of the power supply at the DUT can be significan...

FAQ 2007-06-01

How do I clear non-volatile memory locations for security purposes?
For Keysight Model 66000A, each module has 5 states where data can be saved (0 to 4). State 'zero' is the wake-up state. To clear all states, save ZERO into each state.
