7. Set the 8566A/B controls as follows:
Reference level ...................................................... +10dBm
Center frequency ................................................. 10.7MHz
Span ..............................................................................0Hz
Resolution bandwidth ........................................... 300kHz
Video bandwidth .................................................... 300kHz
Sweep time ....................................................................5.5s
Trigger .......................................................................Single
8. On the 8566A/B, press
SHIFT, (trace A blank) to set detector to
SAMPLE mode.
9.On the 8564EC or 8565EC spectrum analyzer, pressPRESET
and set the controls as follows:

STATE on the 8564EC or 8565EC spectrum analyzer. The IF
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 Figure 9-8 on page 458. If the
signatures do not closely resemble each other, a more detailed view
of the signature may show the failed hardware.
