MARKER
Active markers are normally displayed as intensified dots on a CRT
display. With
Amp1
Markers selected, active markers are displayed
as amplitude spikes (an abrupt discontinuity in the sweep trace).
The marker amplitude can be varied. The swept signal generator
displays:
-->
AMPLITUDE MARKER SIZE:
XXXX
dB.
Where XXXX
represents an amplitude value. Use the rotary knob, the step keys,
or the numerical entry keys with the dB(m) terminator key to
set the desired value. If a small change is required, the left and
right arrow keys can be used to underline the digit to be changed.
Select
Amp1
Maskers again to return to the normal intensified dot
representation. See “Specifications” for the range of acceptable
amplitude values. An asterisk next to the key label indicates this
feature is active.

Description
This softkey (Option 002 only) scales the amplitude modulation
exponentially. Amplitude modulation lets the RF output of the
swept signal generator be continuously and exponentially varied at
a rate determined by the AM input or at a rate set by softkey for
internal AM. See “Specifications” for the AM characteristics, input
range, and damage level. An asterisk next to the key label indicates
that this feature is active.
