Modules characteristics
The Keysight DAQ970A 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 DAQ970A's internal DMM connections

are accessible only through the DAQM900A, DAQM901A,
DAQM902A, and DAQM908A 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 DAQM905A RF Multiplexer uses SMB
connectors. A standard set of (10) BNC-to-SMB adapter cables is
provided with each RF module for convenient BNC connections.
