4.11 - Signal Processing
4.11.1 - Auto Noise Floor
determines the average level of the noise floor over time and adjusts the position of the RF display wave downwards to position the baseline two divisions from the base of the plot.
4.11.2 - Smooth Noise Floor
uses advanced DSP techniques to adjust the display of the spectrum and waterfall noise floor to make it easier to see signals, and to reduce disruption by impulse signals such as lightning static.
The result is less complexity in the waterfall at low signal levels, and more distinct visualizations of stronger receivable signals in both the RF spectrum display and the waterfall display.
4.11.3 - Low Pass Filter
You turn on the low pass filter with . You adjust the low pass filter frequency with Lpf.
Low pass filtering is useful when there is a lot of hiss, or you think you're hearing too much pre-emphasis.
