3.1 Measuring a Sine Signal
The most basic task of an analyzer is measuring the frequency and amplitude of a
signal. In the example below, we use a generator (such as RIGOL DG3101A) to
output a sine signal at 100 MHz and -10 dBm and we will use this as the signal to
measure.
Procedures:
1. Device attachment
Connect the output terminal of the generator to the RF INPUT 50Ω terminal on
the front panel of the analyzer.
2. Use Marker to measure
(1) Reset the analyzer
－Press Preset
(2) Set the parameters
－Press FREQ
－Press Center Freq and enter 100 MHz.
－Press SPAN
－Press Span and enter 10 MHz.
(3) User the marker
－Press Marker
A marker is activated.
－Press Peak
The peak is identified by a marker, and the frequency and amplitude of this
signal are displayed at the top right of the grid.
3. Measurement result
The frequency and amplitude of the signal under measure is 100 MHz and -10.05
dBm, see figure below.
