3. Transfer SCLK (TP148) to the frequency counter.
4. Send batch file “SETFREQ nn” to set the clock frequency. The
default value of nn is 80. Increase the value to increase the
frequency and vice-versa. The clock frequency must be 3,456 kHz
( ± 0.007 kHz).
14.4. QUICK Tx CHECK
1. Set the CMD60 to MODULE TEST.
2. Send batch file “H”.
3. Confidence check of Power (NTP): it must be +20 to +25 dBm.
4. Confidence check of Frequency Offset: it must be 0 ± 40 kHz.
5. Confidence check of Deviation of B field Data Type 01010101: it
must be 207 to 270 kHz.
14.5. LOOPBACK TEST
1. Set the CMD60 to MANUAL TEST.
2. Set the CMD60 TRAFFIC CARRIER to 5.
3. Send batch file “TESTMODE”.
4. On the CMD60, press “SETUP CONNECT”.
5. Check the Power (NTP): It must be +20 to +25 dBm.
6. Press MODULATION.
7. Set Data Type to “Fig.31”.
8. Check the Frequency Drift: it must be 0 ± 45 kHz/ms.
9. Check the Frequency Offset: it must be 0 ± 40 kHz.
10. Send batch file
ì
WREE 00 16 nmî to adjust the Deviation (Max. B
Field) with Data Type: 01010101. Increase the value nm to
increase the Deviation and vice-versa. The least significant digit
(m) of the value must be 1 (i.e. only the values 31, 41, 51, 61 etc.
are allowed). The Deviation must be 207 to 270 kHz.
11. Check the Deviation (Max. ± B Field) with Data Type “Fig.31”: it
must be 202 to 404 kHz.
12. Press MENU UP.
