Message 1 of And for the NULL modem. Message 17 of I have installed the driver of NI for Labview version 5. The current address is displayed momentarily on the front panel when you turn on the power supply. Problems with the driver for the HP EA.

They both don’t work and as they are quite new, I am pretty sure they are not broken.

You need to make sure that you set the current value up high enough that the power supply does not go into limiting mode. Most Active Software Boards: Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

So I began taking a closer look at labvieew driver in Highlight Execution mode and started decoupling all the stuffs which made problems: During my research online, I have found out that prolific chips have kind of a bad reputation.

After I switched this setting on the device, I was able to set labvie via RS Most Active Software Boards: Furthermore, both agilent machines are DTE. The attached vi shows proper use of error wires. Everything worked the same.


Message 6 of If we cannot see “what you did wrong”, we are unable to tell you how to fix it. So my first fault were the front panel settings, and my second one was a e3631x NULL modem.

I guess the 8-ball is working fine today. Do you have the correct combination of NULL modem, gender changer and cable?

If you are actually sending and receiving commands to the power supply, then what you have must be a NULL modem. Hull Law Labvieq Diagram.

Agilent E363X Series Power Supply

Message 1 hhp 5. The BK precision one has its own converter and for the other 2 I use this converter: Sorry, I am quite new to the world of online communities, and have made a blunder by crossposting.

Agilent Technologies controllers generally use address “21”. The text commands mean nothing to me and I can’t take the time to check each command. If the BK precision should work, what could be the problem then?

Instrument Control (GPIB, Serial, VISA, IVI)

I prefered to writed my own driver using the GPIB commands. Here is the way it is done with my drivers.


Message 9 of It’s part of a program to create a voltage vs current graph. After that I had to remove the error queries from the Configure Output and the Configure Current Limit as well, which made these work too. Message 10 of As a precaution, you want to set your limits according to your test needs so as not to apply too much voltage to a circuit or allow too much current to flow in the event of a short circuit.

Message 20 of Without me doing anything, instead of going to 0, the output is shutting off. If the unit is in constant current mode, altering the voltage will not have any effect on the output voltage. That made the initialize sub VI run.
