General description
The Frequency shift shifts the original signal in the frequency domain by the given amount of Herzes. With the frequency lock switch, an automatic frequency scanning mode can be activated. In the scanning, the user can give the target frequency and scanning area. SkySweeper automatically tracks the most powerful frequency component in the scanning area, and then calculates the necessary amount of the frequency shift, so that the output signal frequency peak is in the given target frequency. This is especially useful in tracking sinusoid signals.
Configuration
Pressing the 'Config' button opens the following configuration dialog.
Parameters
Frequency trackingThis switch activates the frequency tracking function. In the frequency-tracking mode the frequency shift value is automatically calculated in real time.
Target frequency
The Target frequency tells the frequency where the frequency with most power in scanning area is shifted. This parameter is active only in the frequency-tracking mode.
Scanning area
This is an area where the frequencies are scanned. The frequency shift is automatically calculated so that the frequency with most power will be in the target frequency in the block’s output. This parameter is active only in the frequency-tracking mode.
Update interval
The Update interval is the interval between automatic frequency shift estimations. This parameter is active only in the frequency-tracking mode.
