Select Channel 0
7. Set the Signal Generator to the Channel 0 carrier frequency, with a 1000Hz modulation
signal, a deviation of ±1.5 kHz and a RF level of -90dBm.
The RSSI barchart display should now be (typically) well above a reading of 20 - if so,
jump to step 9.
8. If the RSSI is not visible or is very low, Manual Tuning may be required. To do this, adjust
the four Filter sliders (1-4) in combination for the maximum RSSI reading or for the best
sinad reading. Proceed to step 9 when an RSSI of better than 20 is achieved.
Note: For optimum results, the sliders should be adjusted to be approximately in line.

Select Auto Align.
The front end will be tuned automatically.

Verify that the receiver sensitivity is better than -117.5dBm for 12dB sinad. (Sensitivity is
typically -120dBm).
