Warm-up time For standard mainframe operation, plug-in specifications are valid after a one-
hour warm-up period. For operation with the module extender, specifications
are valid after a
two-hour warm up period (with the extender installed in
the mainframe and the plug-in installed in the extender bay).
Trigger to signal
delay The displayed timebase values will not be correct when operating a plug-in
with the module extender. The characteristic delays below must be added to
the displayed value to obtain the correct approximate delay from the trigger
signal.
Trigger sensitivity The extra length of trigger cable in the module extender results in additional
loss at high frequencies. This loss must be considered when calculating trigger
sensitivity.
A trigger input is provided at the mainframe end of the Agilent 11898A mod-
ule extender module extender. Triggering at the mainframe is recommended
for applications requiring the highest sensitivity, and for the enhanced trigger
option (Option 100) of the mainframe at frequencies greater than 2.5 GHz.
