Two Tone Test:
Used to test the two-tone IMD of the transmitter. To run the test, enter the two tone frequencies in the
Freq #1 and Freq #2 controls. Enter the Power to be sent to the front panel Drive control. Make
sure you have a dummy load connected. Click the Start button to begin transmitting a side-tone signal
using the parameters entered. Manually adjust the Power control on this tab to set the tones to 6dB
below PEP using a spectrum analyzer. Click the Start button again to stop the test and read the Power
value thus found. A single sweep function on a spectrum analyzer is an excellent tool to capture the
output for analysis.
Audio Balance Test
Use this test to ensure that the Powered Speaker/Line Out cable is getting both output channels. The
test will send a tone to each speaker and prompt to see if you hear audio in that one speaker. If you
hear no audio or audio in both channels during this test, then either the connector is not properly
seated or you may have a problem with the cable going to the Powered Speaker/Line out jack on the
Back Panel.
