1. Set the CMD60 to MODULE TEST.
2. Send batch file “H”.
3. Confidence check of Power (NTP): must be +20 to +25 dBm.
4. Confidence check of Frequency Offset: must be 0 ± 40 kHz.
5. Confidence check of Deviation of B field Data Type 01010101: must be 207 to 270 kHz.
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 Power (NTP): must be +20 to +25 dBm.
6. Press MODULATION.
7. Set Data Type to “Fig.36”.
8. Check the Frequency Drift: must be 0 ± 45 kHz/ms.
9. Check the Frequency Offset: must be 0 ± 40 kHz.
10. Send batch file “WREE 00 51 nm” 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 202 to 280 kHz.
11. Check the Deviation (Max. ± B Field) with Data Type “Fig.36”: must be 280 to 370 kHz.
12. Press MENU UP.
13. Press POWER RAMP
14. Check the Burst fits mask.
15. Press MENU UP.
16. Press BER.
17. Note the Sensitivity (reduce the RF LEVEL for a BER of approx. 1000ppm) : RF LEVEL must be < – 90 dBm.
18. Press MENU UP.
19. Press BEARER RELEASE.
