The SCXI-1127,SCXI-1128 and SCXI-1129 have the capability to route analog signals to their rear connector. If you want to share these signals among several modules, you need to use the high-voltage analog bus (HVAB) adapter (like the SCXI-1357 and SCXI-1358). With this adapter and with an HV8-BAN4, you can route these signals to one of NI DMMs, like the NI 4060 or NI 4070.
Now if you are not using one of NI DMMs and you want to know how to connect an external instrument to the HV8 connector, I would strongly recommend that you contact NI support for more information at
