Example:
Separating Two Signals
The two signals have a level of -30 dBm each at a frequency spacing of 30 kHz
Table 3-5: Signal generator settings (e.g. R&S SMU)
Level Frequency
Signal generator 1 -30 dBm 128,00 MHz
Signal generator 2 -30 dBm 128,03 MHz
1. Set the signal analyzer to the default state by pressing the [PRESET] key.
The R&S ESR is set to its default state.
2. Select "Spectrum" mode.
3. Set the center frequency to 128.015 MHz and the frequency span to 300 kHz.
a) Press the [FREQ] key and enter 128.015 MHz.
b) Press the [SPAN] key and enter 300 kHz.
4. Set the resolution bandwidth to 30 kHz and the video bandwidth to 1 kHz.
a) Press the [BW] key
b) Press the "Res BW Manual" softkey and enter 30 kHz.
c) Press the "Video BW Manual" softkey and enter 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.
