The IF bandwidth setting selects the bandwidth of the receivers. The IF bandwidth value takes value from the following series: 1 Hz, 1.5 Hz, 2 Hz, 3 Hz, 5 Hz, 7 Hz, 10 Hz, 15 Hz, 20 Hz ... 1 MHz, 2 MHz. The maximum IF bandwidth value depends on Analyzer model (See corresponding datasheet).
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 increases the measurement time.
The IF bandwidth is set for each channel independently. The channel to which the function is applied must be preselected as active (See Selection of Active Trace/Channel).

IF bandwidth can be set using the mouse (See IF Bandwidth Setting). |
