Also applicable to other audio equipment such as audio recorder, DVD, VCD manufacturers and research units.

FM demodulation module.

's special test designed for FM radio transmitter module, can be used for the operation of the FM broadcast transmitter monitoring, can also be used for FM radio transmitter index test and ensure the normal operation of FM broadcast transmitter is indispensable and broadcast equipment.

It has a digital tuning frequency.

There are three sub-systems: frequency synthesizer RF preselector, baseband demodulator, stereo decoder to guarantee the minimum distortion demodulation index.

No need for Bessel zero correction.

It is easy to use, direct output demodulation baseband signal.

The accurate baseband demodulation, PLL stereo channel decoding, linear phase filter, provides a comprehensive and convenient test for monitoring system level and performance detection.
