Key Descriptions
This function is automatically deactivated when the
spectrum analyzer is set to zero span, with a sweep
time less than 30 ms. It is automatically reactivated
when either the spectrum analyzer is set to a span
greater than 0 Hz, or the sweep time is set greater than
or equal to 30 ms with a resolution bandwidth greater
than or equal to 300 Hz. When reactivated, several
sweeps may need to be taken before automatic
adjustment is completed. When reactivated after being
inactive for several minutes, the delay between sweeps
will be longer than usual as the spectrum analyzer does
a complete IF adjustment as quickly as possible. The IF
adjust is also temporarily deactivated while waiting for
an EXTERNAL or VIDEO trigger event.
When
IF ADJ ON OFF is off, an A appears in the special
functions area at the left side of the display screen.
Front-panel key access: CAL
INTENSTY Changes the intensity of the display on E-series
instruments. Press INTENSTY, then use the data keys,
the step keys, or the knob to adjust the intensity. The
intensity ranges from 1 to 255; the current value
appears in the active function block. When
INTENSTY is
pressed,
STORE INTEN appears on the menu. Press
STORE INTEN to store the new intensity value in
nonvolatile memory. EC-series instruments do not
require adjustment and are not adjustable.
For indoor use, keep the intensity around 80. For
outdoor use, increase the intensity as necessary,
keeping in mind that excessive brightness shortens the
life of the CRT.
Front-panel key access:

INTERNAL MIXER Displays the internal mixer softkey menu with signal
identification and preselector peaking. When using
external mixers, this softkey returns the spectrum
analyzer to its internal mixing mode.

NOTE The INTERNAL MIXER softkey and its lower-level softkeys are not
available with an 8560E/EC Option 002. However, the
INTERNAL MIXER
softkey is available with a standard 8560E/EC; its softkey menus are
not.
