R&S FSQ
Measuring Harmonics of Sinusoidal Signals
2. Recouple the video bandwidth to the resolution bandwidth.
➢
Press the
VIDEO BW AUTO
softkey.
3. Reduce the noise by averaging the curve.
➢
Press the
TRACE
key.
➢
Press the
AVERAGE
softkey.
The noise component of the trace will be smoothed by averaging 10 successive traces.
4. Switch off trace averaging.
➢
Press the
CLEAR/WRITE
softkey.
5. Reduce the noise by reducing the measurement bandwidth.
The noise is reduced in proportion to the bandwidth by reducing the resolution bandwidth,
i.e. reducing the resolution bandwidth by a factor of 10 also reduces the noise by a factor
of 10 (which corresponds to 10 dB). The amplitude of sinusoidal signals is not affected by
reducing the resolution bandwidth.
6. Set the resolution bandwidth to 10 kHz.
➢
Press the
BW
key.
➢
Press the
RES BW MANUAL
softkey and enter
10 kHz
.
The noise decreases by approx. 25 dB with respect to the previous setting. Since the
video bandwidth is coupled to the resolution bandwidth, it is reduced to 1 kHz in
proportion to the resolution bandwidth. This causes the sweep time to increase to 60
seconds.
7. Reset the resolution bandwidth (couple it to the span)
➢
Press the
RES BW AUTO
softkey.
