Hi, I need to connect my 2470 SMU to an existing probing setup that uses conventional triaxial connectors (i.e. are used with Keithley 4200 if that helps). However, the 2470 uses Keithley's proprietary (seemingly) TRX-1100V High Voltage Connectors (TRX-1100V HV CONN). 
Has anyone been able to connect both type of triaxial together? I know one can purchase the TRX-1100V HV Triax Cable, but the datasheet seems to indicate that both ends of the cable have TRX-1100V HV CONN, which does not really help in this case.

Many thanks in advance for the help!

The HV triax at rear of 2470 is deliberately different so that “conventional” triax cables from max 200V products cannot connect.

The TRX-1100V-x cable is required for the HV triax on rear panel of 2470.

Maybe what is unexpected:  The male triax connector on this cable is also compatible with “conventional” sized female triax barrels, feed through, etc.  However, do keep in mind the 1100V rating.
There are various TRX-1100V-xxx accessories.  Also our legacy 237-xxx accessories are also rated for 1100v and are compatible with the HV triax cable.

I advise you to consider the voltage rating of the probing setup and use 1100V components throughout.
