Modules specifications
The Keysight 34970A/34972A accuracy specifications
already include the switching offset and reference junction
errors shown below. These errors are listed separately
for determining system error with external measurement
devices.
Up to three modules, in any combination, can be inserted
into a single mainframe. The 34970A/34972A’s internal

DMM connections are accessible only through the 34901A,
34902A, and 34908A low-frequency multiplexers.
On-module screw terminals accept wire sizes from
16 gage to 22 gage. Twenty-gage wire is recommended for
high channel count applications. The 34905A and 34906A
RF Multiplexers use SMB connectors. A standard set of
(10) BNC-to-SMB adapter cables is provided with each
RF module for convenient BNC connections.
