N O T E
To ensure traceability, use the 81610CC Reference Cable for
calibration measurements. Do
not
use the 81610CC Reference Cable
for measurements on a Device Under Test. Instead, use a measurement
patchcord.
C A U T I O N
It is important to maintain the quality of the straight connector end of
the 81610CC Reference Cable.
Never
add another connector to the
straight end of the 81610CC Reference Cable, since a physical
connection is made. When the straight end of the 81610CC Reference
Cable is connected to the 81634B Power Sensor module, no physical
connection is made so there should be no degradation of connector
quality.
