3-8 Sweep Frequency
Operation
The signal generator can generate broad (full range) and narrow band
sweeps across the frequency range of the instrument. The MG369XB
has four sweep frequency modes—analog sweep, step sweep, manual
sweep, and list sweep. Descriptions and operating instructions for the
analog sweep frequency mode begins on this page. Step sweep fre

Sweep, Step Sweep, Manual Sweep, and List Sweep frequency mode
menu maps (Chapter 4, Figures 4-3, through 4-6) to follow the menu
sequences.
Analog Sweep
Mode
In analog sweep frequency mode, the MG369XB's
output frequency is swept between selected start
and stop frequencies. Sweep width can be set from
1 MHz to the full frequency range of the signal gen

erator. Sweep time can be set for any time in the
range of 30 ms to 99 sec. The lower frequency limit
for analog sweeps is 10 MHz (500 MHz with Op-
tion 4).
When the sweep width of the analog sweep is
>100 MHz, the sweep is phase-lock corrected at both
the start and stop frequencies and at each band
switch point. When the sweep width is £100 MHz,
only the center frequency is phase-lock corrected.
