11.Simultaneously press
on the 8564EC or 8565EC spectrum analyzer. The IF
STATE
signature is displayed on the 8566A/B display. It may be necessary to
experiment with different time intervals between initiating the
sweep on the 8566A/B and initiating the current IF state adjustment
on the 8564EC or 8565EC spectrum analyzer.
12.Compare the IF signature to the signature of a properly operating
spectrum analyzer illustrated in
signatures do not closely resemble each other, a more detailed view
of the signature may show the failed hardware.
