If you want to try a copy shoot me an email. If it works out, I'll see if John wants to include it in the standard toolkit distribution. You will need to download GPIB tool kit from the KE5FX.COM web site, run the tool kit configuration program (PROLOGIX.EXE) to setup it up for your interface (it works with Prologix and NI compatible interfaces), copy my HP3458.EXE program to the GPIBKIT directory and run it. Check the comments at the start of HP3458.CPP for some info. Run HP3458.EXE without any command line arguments for program usage help.

[volt-nuts] 732A and Prologix received
I received my Fluke 732A today. Just powered it up but it needs new batteries. Any suggestions for sources (I haven't opened up the unit yet - I want to make sure it works before doing that). Also received the ProLogix USB-GPIB adapter. I plan on using Mark Sims' CAL ran data dumper program to get the CAL data from my 3458A. Should be a busy weekend.

[volt-nuts] 732A drift
I hope someone can help with a strange anomaly on either my 3458A or the 732A. The 732A 10V output as measured on my 3458A seems relatively stable over time (it bounces around about +/-1 uV but is it the 732 or the 3458?). However, the 1.000 VDC output drifts downward at a rate around 1-2 uV per second as soon as I plug the 3458A into the 732 output. If I remove the 3458A and connect it back up after a few 10s of seconds, the reading goes back to what it started at and then drifts downward again. The 1.018V output also drifts downward but at a much slower rate and not as much. Now the question is: is it the 732 or the 3458A? I tried to see it on my Agilent 34401A DMM but it really doesn't have the resolution, but I do seem to see it on the 1.000VDC output. If it is the 732A, what would cause it to drift downward like that? Since the 3458A has an input impedance of 10Gohm on the 1 and 10 V ranges, I wouldn't think the 732 would even see the difference of whether the 3458A is connected of not, but it clearly makes a difference as to how long its connected and how long it's been disconnected. Any one have any conjectures? Also, what will turn on the In Cal light? What does it mean if it doesn't come on?
