[time-nuts] Multiple Voltage monitoring

[Mark Sims]

Tektronix TM5003 or TM5006 power supply mainframe.  DM5010,  DM5110,  or DM5120 meter.  SI5020 input scanner. 

In place of the meters/scanner you could use the MI5010 multifunction interface with the 50M10 A/D card and a 50M40 or 50M41 relay scanner.  Even better use an analog switch on the 50M70 development board or controlled by a 50M30 parallel I/O board.

With a little shopping on Ebay you should be able to configure the system for around $300.

Another possibility is a HP3457A meter with the relay card (or your own analog switch).

All of these systems would measure the voltages sequentially,  not simultaneously.   

I have seen some other HP meters with GPIB sell for under $50.  You could just chain a bunch of them on the GPIB bus.
