Step function of Fluke PM28xx

[SvenC]

Hi,

I have a technical question about the Fluke PM2813 programmable power supply. I use this device in a test environment that is controlled by a computer via the GPIB bus.

Here it is: What do I have to do if I want one of the outputs of the Fluke to ramp up from 0 to 5V and I want to hold the voltage on the other outputs constant during this ramping. The problem is when I use the step function to ramp up one channel, the other channels also change.

I know I can read the output of the other two channels and copy that value to the necessary memory locations before ramping but that way takes about 11 seconds before all GPIB commands are processed and the actual stepping begins. That way to long...

Is there another way to accomplis
h this in a much shorter time?


Thanks,
Sven Callewaert

Hi Sven,

I'm not familiar with this particular instrument, but seems like something you should be able to find in the documentation for the instrument.

Are yo using an instrument driver?. What programming enviroment (CVI, LabVIEW)?
