Keithley2400 -- how to increase the source voltage for 1mV in remote command?

[Ian]

Hi, Folks,

I am using HPVee to programe a Keithley2400 digital source meter. I
want to set a remote command to increment the output voltage for 1mV.
The command should be ":SOUR:VOLT:???? 1mV". What should the ???? part
be? Does someone know it? I couldn't find it in the manuel.

Thanks in advance.

Hi Ian,

First of all : The K2400-SMU has to be set in Voltage range of 21V - or lower
( in 21V- range the programming resolution is 0.5 mV / / in 210V-range the prog. resol. is 5 mV !!)

Format string for numbers is in this case %.4e;
( engeneering format )

The requested GPIB - string has to be
:SOUR:VOLT 1.0015E+0;
for e.g. 1.0015 Volt

Hope this helps
Regards
wha

And if Ian didn't have the bad luck to be programming in VEE instead of LabVIEW, then he'd have a driver to do all the settings for him. Also, he was looking for a command to increment the output. Though it's been a while since I used the instrument, I don't think there is such a command - only the command to set it as wha describes. If you need to increment and aren't keeping track of the output setting in the program, query the instrument for it's current setting and add whatever you want to it, and use the SOUR:VOLT command to change it.

Thanks folks,
I will try what wha pointed out. However, I figured out a way to
incremen
t it by indicating the buttons that I want to push, therefore
it is like physically pushing the buttons. The buttons are numbered in
the menual. It's kind of stupid but, hey, it works for the moment.
Talk soon.
