Measuring CW Signals
A basic task for spectrum analyzers is to measure the level and frequency of sinewave
signals. The following examples illustrate an effective way of performing these mea-
surements.
A signal generator, e.g. R&S SMBV provides the signal source.
Test setup
Connect the RF output of the signal generator to the RF input of the R&S Spectrum
Rider.
Signal generator settings:
●
Frequency: 500 MHz
●
Level: -25 dBm
Measuring the level
1. Press [PRESET] key.
The R&S Spectrum Rider is reset to its default state.
After the preset, the R&S Spectrum Rider displays the frequency spectrum over its
full frequency span.
At 500 MHz, the generator signal is displayed as a vertical line. To analyze the
generator signal at 500 MHz in more detail, reduce the frequency span.
2. Select the "Center" softkey at the "Parameter view".
The R&S Spectrum Rider opens an entry box to define the center frequency.
3. Enter a center frequency of 500 MHz.
The signal is now in the center of the display.
4. Select the "Span" softkey at the "Parameter view".
The R&S Spectrum Rider opens an entry box to specify the span.
5. Enter a span of 20 MHz.
The R&S Spectrum Rider now displays the generator signal with a higher resolu-
tion.
