Modules specifi cations
The Agilent 34970A/34972A accuracy specifications already
include the switching offset and reference junction errors
shown below. These errors are listed separately for deter-
mining 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.
