Selects the Receive Frequency in MHz.
Selects the Digital test pattern - TIA. Choices are: Standard Tone
Test Pattern (framed 1011) and Standard Interface Test Pattern
(CCITT V.52).
Selects the digital modulation type of the incoming signal on which
BER is to be calculated.
Allows the user to adjust the number of test repetitions. A selection of
Yes will cause the radio to calculate BER on a continuous basis
indefinitely and update the results on this screen after each
integration time. A selection of No will cause the BER test to execute
only one sample and then update the display.
NOTE: When Continuous Operation = Yes, all fields will be grayed
out while the test is in progress. They will be enabled when
the test is complete, or if the STOP button is pressed.
When Continuous Operation = No, a wait cursor will be
displayed while the test is in progress and return to normal
when the test is done.
