Marker Operation
The swept signal generator has ve frequency markers that can
be used as xed frequency \landmarks," or as variable frequency
pointers on a CRT display.To view the marker features of the swept
signal generator on a CRT, connect the swept signal generator as
shown in Figure 1-8.
Refer to menu map 3, MARKER.

The swept signal generator is sweeping from 3 to 7 GHz, with a
100 ms sweep speed. A frequency marker is set at 4 GHz, which
causes an intensied dot to app ear on the CRT. To obtain an
amplitude spike at that frequency, select
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
Ampl Markers . Notice
that you can set the amplitude of the spike with the rotary knob or
entry keys. To return to the intensied dot representation, select

Ampl Markers (asterisk o ).
Caution
Amplitude markers increase the output power at the marker
frequency. Provide protection to devices that could b e damaged.
