The plot below shows the following signal data:
Center frequency (CF) : 84.0 MHz
Frequency span:
Start frequency :
End frequency:
Step bandwidth:
In this example, one step represents a bandwidth of 31.25KHz.
Center frequency (CF)
Press the CENTER FREQ. soft key to make the center display readout appear in the
reverse contrast. Enter a desired frequency via the numeric keys followed by the MHz key.
This becomes the center frequency.
Frequency span (SPAN)
Press the FUNC key, then press the STEP key to reverse the contrast of the SPAN
numeric display. Enter the frequency span over which you wish to monitor, using the
numeric keys followed by the KHz key or the MHz key to confirm the entry. The display
step will be automatically calculated but the value is not displayed on the LCD.
