Option 100 Fault Location and SRL 8-9
Key Reference
Alphabetical Key Reference
Softkey in the fault location menu. Available only when
is selected. When this softkey is pressed, you will be
prompted to enter a new center frequency. You can retain the current
center frequency if you wish by just pressing . The analyzer
will select the proper frequency span for your measurement.
The center frequency should be set within the operating frequency
bandwidth of the transmission line being tested. The center
frequency can only be set to a value which will not result in the
source going beyond its frequency limits.
See “Start/Stop Distance and Frequency Span Explanation” on
page 1-5 for an explanation of how the analyzer determines the
frequency span.
Access Keys:
Softkey in the connector model menu. This softkey is available only
while in SRL measurement mode.
The connectors used to interface to the cable under test are not ideal
and can have some mismatch. This effect can usually be canceled out
by entering a small value of capacitance using the
softkey. The typical value of compensating capacitance (if needed) is
−0.1 pF.
Access Keys:
or
(You must already be
in SRL measurement mode to access the connector
model menu via the key.)
