TRANSCEIVER OPERATIONS
By rotating the Mult i 1 knob, choose the band which you want to adjust - marked with the green
rectangle.
By rotating the Mult i 2 knob set the required level for each band.
Note:
(
Equalizer tuning could be performed with the help of the mouse, by dragging the equalizer
slider up and down.
(
Also equalizer tuning could be performed with the help of the transceiver's
touch-screen
panel, by dragging the equalizer slider up and down with your finger. пальца руки.
7.21 DSP Functions
MB1 transceiver has several Digital Signal Processing functions for improving received signals.
The list of the available DSP functions:
·
NR - Noise reduction.
Adaptive filter for the noise-like crosstalks, allows to clear the signal from the crosstalks.
·
NB1 - First Noise Blanker .
Noise Blanker with approximation - algorithm 1.
·
NB2 - Second Noise Blanker.
Noise Blanker with approximation - algorithm 2.
Note:
(
The NB1 and NB2 algorithms are different. Try each of them to reach the best impulse
interference reduction.
NB1 and NB2 Noise Blankers can also be used simultaneously.
(
NB1 and NB2 thresholds could be adjusted in the software settings (more details in
) or with the knobs on the front panel of the transceiver
(w ill be available in the new
software releases ).
·
ANF - Automatic Notch Filter.
Adaptive reject filter for the periodic signals/crosstalks - narrowband, carrier, CW and other
signals.
Note:
(
If there are no interference, ANF could slightly affect the reception quality of the desired
signal. Disable ANF , if you don't need it.
