Decreasing The Time Delay; Using Stepped Sweep Mode - Agilent Technologies 8719D User Manual

can be used to check the data. The disadvantage of the stepped-frequency mode is that it is
slower than sweeping.

Decreasing the Time Delay

The other way to reduce AF' is by decreasing the time delay, AT. Since AT is a property of
the device that is being measured, it cannot literally be decreased. However, what can be
decreased is the difference in delay times between the paths to the R sampler and the B
sampler. These times can be equalized by adding a length of cable to the R channel which has
approximately the same delay as the device under test.
This length of cable can be inserted between the R CHANNEL IN and OUT connectors on the
front panel of the analyzer. The delay of this cable must be less than 5~s.
