Solution
Attach the sleeve antenna M401 to MSA538, and the signal of the wireless module under communication can be measured.
- The duration of transmission can be measured by the dual view analysis of “Power vs time” and “Spectrogram”.
In a example below;
Down link:23.2 ms | Up link:24.8 ms | Interval:2.0 ms
- The measurement of frequency variation of GFSK signal can be performed by switching the main screen to “Frequency vs time”.
In a example below;
Transition frequency : +/-40 kHz | Symbol rate : 9600 bps
