To all I will add a little to what previous emc-pstc denizens have said about the 34970A. I use this unit extensively for production, HALT and safety testing. This unit can be ordered (recommended) with the DMM option. This will make the unit similar to the 34401 DMM, my favorite 6.5 digit meter. It is good-to-go out of the box w/supplied software.
I would attempt to avoid using the serial port; you will eventually want to control several instruments, and GPIB is currently the only practical/robust solution for this...(at least until something like USB/1394 is on everything). I have used many ISA/PCI bus-based data acquisition boards, and have had "more than one problem" with these solutions; and always return to discrete instruments. I also prefer to use instruments that have embedded SCPI. Also, calibration of "I/O cards" can be problematic. I am not certain that you can demonstrate tracibility of these "cards" from one computing platform to another; and all of the agencies I deal with accept data from the 34970, but some tend to doubt data from these "I/O cards." Avoid writing a lot of user interface code. It will only detract from the primary purpose of evaluating the UUT and test documentation. If using a Win-tel box, consider using COM/ActiveX to glue and stream data between the device driver and Word/Access/Excel/Etc. Let other people do the "Grunt" coding, you are doing compliance engineering. Most data acquisition tasks are already "built into" MS Office or Lotus SmartSuite. -----Original Message----- From: richwo...@tycoint.com [mailto:richwo...@tycoint.com] Sent: Monday, May 06, 2002 11:14 AM To: emc-p...@majordomo.ieee.org Subject: Thermal Testing Do any of you monitor and record component temperatures during safety testing using PCs and data capture I/O cards?
