4.8 Basic Measurement
Basic measurements include, input signal frequency and amplitude display, marked by a frequency marker. Follow these four
simple steps below to implement input signal measurement.
Basic:
1. Setting center frequency;
2. Setting span and resolution bandwidth;
3. Activate marker;
4. Setting amplitude;
For example, to measure a 100MHz -20dBM signal, you must turn on the spectrum analyzer and ensure it is warmed up for
30 minutes to ensure measurement accuracy.
1. Equipment connection:
Connect the output terminal of signal generator to the RF Input 50Ω terminal of spectrum analyzer. Set the parameters as
follows:
Frequency 100 MHz
Amplitude -20 dBm
2. Setting parameters:
1) Press [Preset] to restore the analyzer to its factory-defined state. The Spectrum analyzer will display the spectrum from
9kHz to the maximum span width. The signal generated will display as a vertical line at 100MHz. Refer to Figure 4-8
