Used blonder tongue digital/ analog analyzer btpda-4
The BTPDA 2 and 4 are professional quality analyzers for measuring analog and digital signals (64 QAM, 256 QAM, OFDM, 8 or 16 VSB). Both instruments have an operating frequency range from 5 to 870 MHz, which supports measurements on off-air channels (2-69), CATV channels (2-135) and sub band channels (T7-T14).
