This report presents the transmitter spectrum mask measurements conducted on the Tait TMCN0B radio, adhering to FCC and RSS standards. The tests were performed by TELTEST Laboratories, with report number 4402. The primary specification guiding these measurements is FCC 47 CFR 2.1049 (c), complemented by ANSI C63.26.5.7.3 and RSS-119 5.5.
The measurement procedure involved setting up the equipment as per Annex A. For analogue measurements, the EUT was modulated using a 2500 Hz tone, ensuring the input level was 16 dB above the level producing 50% deviation. Data measurements utilized an internally generated pseudo-random bit sequence at appropriate Baud rates. The spectrum analyser was used to measure the occupied bandwidth, with specific bandwidth settings noted in the recorded plots.
The report includes detailed results in the form of plots, illustrating the emission masks for various channel frequencies and modulation types, including Analogue, FFSK, and Digital Voice/Data. The channel spacing configurations tested were 12.5 kHz, 20 kHz, and 25 kHz. Data speeds for Digital Voice/Data and FFSK were also recorded. The uncertainty of measurement is ±0.65dB. The limit clauses are FCC 47 CFR 90.210 and RSS-119 5.5. The FCC ID for the device is CASTMCNOB, and the IC is 737A-TMCNOB.
