Radio Alignment Procedures
33
Test Pattern:
This field selects the Digital test pattern — TIA. Choices are: Standard Tone Test
Pattern (framed 1011) and Standard Interface Test Pattern (CCITT V.52).
Modulation Type:
This field represents the digital modulation type of the incoming signal on which
BER is to be calculated.
Continuous Operation:
This field allows the user to make the BER test repeat indefinitely. A selection of
Yes will cause the radio to calculate BER on a continuous basis and update the
results on this screen after each integration time. A selection of No will cause the
BER test to execute for only one sample of the integration time and then update
the display.
Audio:
This field allows the user to select the audio output during a test. Selecting Internal
will cause the radio's built-in speaker to unmute to any signals at the desired
frequency which are present during the test. Selecting External will route the same
signal to the radio's accessory connector audio output. Selecting Mute will disable
the audio output.
Integration Time:
This field represents the amount of time over which the Bit Error Rate is to be
calculated. The range is from 0.360 to 91.8 seconds in increments of 0.360
seconds.
NOTE: When Continuous Operation = Yes, all fields will be grayed out
while test is in progress. They will be enabled when the STOP
button is pressed.
