FAQ: What is the output response time of the Keysight N8900-series power supplies when programming a dropout pulse?

The following diagram illustrates the response time for a dropout pulse from 90 % to 10 % of full-scale into a resistive load. Note that this waveform only illustrates the analog response. Programming response time, which is typically 25 ms, must be added to the analog response time.

The dropout (down-programming and up-programming) response time of the N8900-series is documented in the User’s Guide. Seehttp://literature.cdn.keysight.com/litweb/pdf/N8900-90901.pdf

Be aware that the down-programing time (falltime) with an open circuit can be as long as 30/40 seconds for the highest-rated current models, and as long as 10 seconds for all other models.
