Input test signal
Input test signal connections can be made using the DAQM901A multiplexer
module to interface to the output sources (see “Recommended Test Equipment”
on page 36). Shielded, twisted-pair, PTFE interconnect cables of minimum length
are recommended between the calibrator and the DAQM901A multiplexer module
channels to reduce settling and noise errors.
– HI and LO should be a twisted pair (Channel 302).
– HI-Sense and LO-Sense should be a twisted pair (Channel 312).
– AMPS and LO for DC/AC current should be a twisted pair (Channel 321).
All test cable shields should be tied to Input LO and ground referenced at the
calibrator's output terminals. This configuration is recommended for noise
reduction and settling time performance during calibration.
