Tester of communication line pilot signals

This distributed test system consists of 6 stations interconnected by a modem link to the central control room. Each station tests the received and transmitted pilot signal on communication analog lines as well as the 220V AC supply network. The level of the pilot signals is obtained by calculating the FFT from the measured data spectrum. In the control room, the actual value of the pilot signals is always available in numerical and graphic form from all stations. The software is custom-made prepared in the TestPoint graphical environment.

Properties:

• testing of communication lines,
• distributed system, distance of individual stations from 10 to 80 km,
• custom software.

Measured units:

Unit	No. of channels	Resolution	Accuracy	Sampling
Pilot signal transmitted (FFT analysis)	6×4	0.5 dB	0,05%	300 kHz
The pilot signal received (FFT analysis)	6×4	0.5 dB	0,05%	300 kHz
Measurement of 220V / 50Hz network	6×1	5V AC	2%
