Hi All,

I need to characterise 25 zener diodes and so I want to automate / semi-automate the process. 
I would like to wire up my diodes to the 34901A plugin channels. Is it possible to then connect
an external instrument in this case a KE2400 to the 34970A such that when initiated the 34970A
will connect via its internal MUX to diode 1 and allow the KE2400 to force a current sweep and
record the voltages then when the sweeps finished switch across to diode 2 and repeat the process
then to diode 3 etc etc. I know I need to write some control test software and triggers etc but I'm
just trying to find out if I can actually connect an external SMU to the 34970A DAQ and it to
function as I need it to ?

I'm surprised that no instrument manufacturing company doesn't have an instrument all in one that 
has the combined functionality of an SMU & Datalogger (with multiple inputs). I have searched for such 
an instrument but cant find one.

Any help or advice would be greatly appreciated

Thanks in advance
