3.8 Measuring the Channel Power
DSA1030/DSA1030-TG that has installed the Advanced Measurement Kit option can
measure the channel power. In the example below, we use a generator (such as
RIGOL DG3101A) to output a sine signal with 100 MHz and -10 dBm as the signal
under 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. Measure the channel power
(1) Reset the analyzer
－Press Preset
(2) Set the parameters
－Press FREQ
－Press Center Freq and enter 100 MHz.
－Press Meas
－Press Meas Fctn and enter the lower menu.
－Press Chan Pwr
(3) Modify the channel power settings
－Press Meas Setup
－Press Integ BW and enter 1 MHz.
－Press CH Pwr Span and enter 2 MHz.
3. Measurement result
The measurement results shown in the lower window are -9.61 dBm (channel
power) and -69.61 dBm/Hz (power spectral density), see figure below.
