Re: Low-noise cables SC-22 and SC-181-1

Thanks for sending the cable mechanical specs.

But I was asking for the transfer impedance and not the cable characteristic impedance.

Low-noise cables SC-22 and SC-181-1

Hello,

I was looking into any measurements or quoted values for noise shielding in the SC-22 and SC-181-1 cables, but couldn't find anything.

Could you please let me know what's the transfer impedance of this cables?

Thanks in advance

6221: External trigger of sweep

I would like some advice about whether it is possible, and what's the easiest way to implement the following setup: - Have source (6221) to initiate sweep after a remote trigger (either on trigger link or SOT) event generated by 3rd party circuit; - Execute all steps in the sweep without interruptio...

Re: 6221 driver problem

Another strange behavior I'm getting, happens in most the AC waveform setting, e.g. in the Labview "KE6221-- Set Sine Wave Params.vi": Everything works, except when I try to set the amplitude of the sine wave to some value <=500nA. In this case the value that is considered by the source is 1uA, and ...

Re: 6221 driver problem

Hi, I'm having the same problem. But I'm pretty sure that my computer uses a '.' as decimal separator, and SCPI commands being sent to source contain '.' as well. I've tried everything, even sending the exact SCPI commands that Labview is generating through Keithley Communicator command line. But ca...
