3.13 Measuring the TOI Distortion
DSA1030/DSA1030-TG that has installed the Advanced Measurement Kit option can
measure the TOI distortion. In the example below, we use generator 1 (such as
RIGOL DG3101A) to output a sine signal with 100 MHz and -10 dBm and generator 2
(such as RIGOL DG3121A) to output a sine signal with 100.2 MHz and -10 dBm as
the signal under measure.
Method 1: (Use marker function to measure)
Procedures:
1. Device attachment
Connect the output terminals of generators 1 & 2 to the RF INPUT 50Ω terminal
on the front panel of the analyzer through a power combiner.
2. Measure frequency and amplitude
(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 1 MHz.
(3) Use marker function to measure
－Press Peak
Execute the peak searching and activate a marker.
－Press Marker
－Press Delta
－Press Peak
－Press Next Peak
Read the value measured by the marker.
3. Measurement result
The result displays in the upper right corner of the screen, see figure below.
