Reception Mode has total (4) four modes for demodulation when

receiving.

Wide-FM

Wide Frequency Modulation

Wide FM RBW (Resolution Bandwidth) 180 kHz

Narrow-FM

Narrow Frequency Modulation

Narrow RBW (Resolution Bandwidth) 12.5 kHz

Amplitude Modulation

SSB /AM RBW (Resolution Bandwidth) 2.4 kHz

SSB

Single Side Band Modulation

SSB /AM RBW (Resolution Bandwidth) 2.4 kHz

The Wide FM mode is ordinary used to interpret a large signal of

bandwidth; the Narrow FM mode is used to interpret a narrow Bandwidth

Signal. AM and SSB can be used irrespective of Bandwidth.

Push
