Performance Testing
6.6.1
Bit Error Rate
This section describes the Bit Error Rate (BER) test of the radio’s receiver at a desired frequency
(see
).
6.6.1.1 Bit Error Rate Fields
Set up the R2670 Communication Analyzer as follows:
1. Connect the RF Input port of the radio under test to the RF IN/OUT port of the R2670 Service
Monitor.
2. Set up the R2670 Service Monitor:
- In the Display Zone, select PROJ 25 STD mode and set the meter to RF DISPLAY.
- In the RF Zone, configure the analyzer as follows:
- In the Audio Zone, select the 1011 Hz PAT code and set the deviation to “PROJ25Dev:
2.83 kHz ~”.
The bit error rate screen contains the following fields:
•
Rx Frequency
:
This field selects the Receive Frequency directly in MHz.
•
Test Pattern
:
This field selects the Digital test pattern to be received by the radio. Choices are: Standard Tone
Test Pattern (Framed 1011), F2 1031, Standard Interface Test Pattern (CCITT V.52) and Phase
2 Digital (1031 Hz) Test Pattern.
•
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 the option to repeat the BER test 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.
NOTE:
There will be
no audio
option available for APX 1000 when performing a Bit Error Rate
Test.
