Automated Performance Tests
INSERT LOSS R->XX
and
INSERT LOSS T->XX
Measures worst-case insertion loss between the test set’s
REFLECTION port or TRANSMISSION port and port XX
when the test set is switched to port XX. Tests the specified
performance of “Insertion Loss,” listed in Table 8-2 in
Chapter 8, “Specifications.”
Steps:
2
•Set specified frequency for test set.
•Perform transmission Enhanced Response calibration with
two test cables (using short, open, load and through). The
calibration reference plane should be between the two
cables.
•Measure insertion loss from each
port XX to test set’s REFLECTION port or
TRANSMISSION port.
•If spec is 16 dB, trace must be above −16 dB.
