1. Select [PRESET] to reset the instrument.
2. Set the center frequency to
128.015
MHz
.
3. Set the frequency span to
300
kHz
.
4. Set the resolution bandwidth to
30
kHz
and the video bandwidth to
1
kHz
.
Note:
Larger video bandwidths. The video bandwidth is set to 1
kHz in order to
make the level drop in the center of the two signals clearly visible. At larger video
bandwidths, the video voltage that results from envelope detection is not suffi-
ciently suppressed. This produces additional voltages, which are visible in the
trace, in the transition area between the two signals.
