| RESPONSE TIMES: |
Remote Command
Processing Time: |
Typically <50ms between receiving the command terminator for a step voltage change at the instrument and the output voltage beginning to change. |
| Power Supply: |
An internal time constant, T, (typically 22ms) governs the settling time of a step voltage increase. |
| NOTE: Settling time to within 1% of the step change = 4.6T, to 0.1% = 6.9T, to 0.01% = 9.2T; for example, after a 10V step the output will be within 1 digit (10mV = 0.1%) of its new value in typically 150ms. For load current of 1 Amp or more, settling times for downward steps will be very similar; however, response times will be longer at low loads |
