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.
