66xxA: Calibration Certificates
Criteria have been established to determine which products get or do not get a calibration from the factory. A product with a product number does not automatically qualify for a calibration certificate.

FAQ 2008-09-22

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 2006-10-21

Can I use Keysight Electronic Loads in series and in parallel?
Keysight electronic loads ARE designed to be operated in parallel for more current, but NOT in series for more voltage.

FAQ 2006-04-11

Ca Keysight power supplies be programmed from 0 to full output voltage using a 0 to 10V signal source?
Yes, many Keysight power supplies feature remote voltage programming or analog programming capability. However, there is a potential danger in analog programming any power supply, especially a high voltage supply...

FAQ 2006-04-11

What are the units used when setting the current slew rate in the electronic loads from the front panel and over the GPIB?
For the N3300A series electronic loads, all slew rate entries from the front panel or over the GPIB are done in the units of amperes per second (A/s).

FAQ 2006-04-11

How do I get my N3300/01A to output a negative going trigger pulse?
The trigger out of the N3300/01A electronic load mainframes is a positive pulse. Many electronic instruments require a negative pulse for a trigger in signal. The workaround is to use the digital port functionality of the electronic load. The d...
