Re: Simultaneous control of multiple instruments over VISA (

Hello, thank you for replies. I have spent some more hours trying to correctly set up the communication and I finally get it work both with single GPIB-USB + GPIB cable between instrument and also with two separate GPIB-USB controllers. The bad thing is that I was unable to exactly define the source...

Re: 4200-MTRX Ultra low noise triax specification

Dear Dale, thank you for you answers. In order to find particular LEMO connectors for our cabling system, I would need standard mechanical specifications of both the SC-22 and SC-181 low-noise triax cables: Ø center conductor (mm), material Ø 1st dielectric (mm), material Ø 1st shield (mm), material...

Re: 4200-MTRX Ultra low noise triax specification

Dear Dale, thank you very much for your valuable answer. I have few more questions: 1) Is there any detailed technical specification of the ultra low-noise cables SC-181 (el. parameters, mech. parameteres)? I didn't find any available info about this cable on Keithley website. I would need to know d...

Re: 4200-MTRX Ultra low noise triax specification

Thank you for your response Andrea. I wonder why this manual is not directly accesible from the product site ( http://www.keithley.com/products/accessories/cables/?mn=4200-MTRX-3 ) - there is just a general selector guide for cables without any technical details. Looking at the manual, I still missi...

4200-MTRX Ultra low noise triax specification

Hello, I am looking for a custom made cabling solution for low-noise triax with higher density of connectors. The standard TRB connectors used in most Keithley triax cable assemblies are unsuitable for this purpose, as they are bulky and difficult to manipulate in limited space. The only triax cable...

Re: 6430 + LabTracer 2.9

Thanks for your advice Dale, but I need a step-voltage measuring profile, not sweep. I measure time series (number of current samples) at each constant voltage step in the defined range (start V, stop V) and the problem here is with the outer loop setting for several repetitions of the whole measure...
