3.10 Measuring the Emission Bandwidth
DSA1030/DSA1030-TG that has installed the Advanced Measurement Kit option can
measure the emission bandwidth. 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 emission bandwidth
(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 EBW
(3) Modify the emission bandwidth settings
－Press Meas Setup
－Press EBW Span and enter 2 MHz.
－Press X dB and enter -3 dB.
－Press BW
－Press RBW and enter 300 kHz.
3. Measurement result
The measurement result shown in the lower window is 303.33 kHz, see figure
below.
