Controling Agilent N6702a Power Supply

[KiloLima]

Greetings,

I am a newbie to using Autoit but figured I would post the question on this forum. I am currently using a Agilent N6702a power supply that I would like to control using Autoit to enable and disable voltage/current on various test products. I was able to use Visa.au3 and Visa.dll and was successful with making a USB connection to the device my problem is I am looking for a sample script on how I could turn on and off voltage/current settings  on a specific channel on the power supply and maybe even try and set multiple staggered voltage settings across a range to test a range of voltages (18Vdc thru 28Vdc).

Thanks in advance for any info

For doing that you need to obtain documentation for the SCPI interface of that specific Agilent device. A 2-second googling turned up this: http://cp.literature.agilent.com/litweb/pdf/5969-2937.pdf#page=16&zoom=auto,70,720

Note that this is only a list of SCPI commands. As they say: "For complete details on the SCPI (Standard Commands for Programmable Instruments) commands, refer to the Programmer’s Reference Help file included on the Agilent N6700 Product Reference CD. This CD-ROM is shipped along with your instrument."

Another 2-second googling found it: http://www.keysight.com/main/editorial.jspx?cc=FR&lc=fre&ckey=781505&nid=-35714.384346.00&id=781505

Very nice programmable power supply BTW. Have fun!

Thanks, I have a scenario that I would like to program and just have not found any good example. I am using a application called "Auto-it" and would like to set the power supply to 18VDC @ 5 amps and run at that voltage for 30 minutes, then increase the voltage to 36VDC @ 5 amps and run for 30 minutes and then return back down to 18VDC  and continue to loop that.

Any good examples?

Thanks Keith

You'll have to first learn AutoIt basics. Use a global While loop with two inner while loops, each performing a dummy but visible action (e.g. ConsoleWrite('I'm doing step X') and then waiting for 30 minutes. Once the skeleton of your app works as intended, replace the dummy action by the required sequence of SCPI commands.
