The IF bandwidth setting selects the bandwidth of the receivers. The IF bandwidth value can be selected from the following series: 1 Hz, 1.5 Hz, 2 Hz, 3 Hz, 5 Hz, 7 Hz, 10 Hz, 15 Hz, 20 Hz ... 200 kHz, 300 kHz.
Narrowing the IF bandwidth increases the signal-to-noise ratio and extends the dynamic range of measurements. Narrowing the IF bandwidth by 10 will nominally extend the dynamic range by 10 dB. Narrowing the IF bandwidth also increases the measurement time.
Setting IF bandwidth
The IF bandwidth is set for each channel independently.
