I.3.2 DIVERSITY/RX2 RECEIVER MEASUREMENT
To begin the test make sure the E4438C signal generator is outputting the proper wave form into the RX2 port on the
transceiver. Next, issue the following commands in XtermW:
STOP
SCHED,DEL,ALL
DSP_MODE,IDLE
DSP_MODE,TEST
L1_TEST,SET,RXPATH,D
L1_TEST,SET,RXENABLE,3,ON
L1_TEST,SET,RXFREQ,value,3
DSP_CMD,SET,BER,RAW
L1_TEST,START,RX
DSP_CMD,BAC,2
SCHED,I,6,L1_TEST,GET,ERRCOUNTS,3,3
where:
value
equals the desired frequency of operation.
Once observation of radio performance is complete, turn off transmit operations by typing:
L1_TEST,STOP
I.3.3 ALTERNATE/TX-RX RECEIVER MEASUREMENT
To begin the test, make sure the E4438C signal generator is outputting the proper wave form into the TXRX port on the
transceiver. Next, issue the following commands in XtermW:
STOP
SCHED,DEL,ALL
DSP_MODE,IDLE
DSP_MODE,TEST
L1_TEST,SET,RXPATH,P
L1_TEST,SET,RXENABLE,3,ON
L1_TEST,SET,RXFREQ,value,3
DSP_CMD,SET,BER,RAW
L1_TEST,START,RX
