C) Continuous Transmission Test
Note:
In the continuous transmission test, the “All 0’s Data” in
ASIC should be used.
Statuses of the CH, spread code, AGC and data are displayed on the LCD
respectively
C: Channel, S: Spread code setting (6 is 600 kHz setting, 3 is 300 kHz
setting, 2 is 200 kHz setting, 1 is 100 kHz setting, 0 is 0 (no spread) and
N is Normal), A: AGC setting (7 is maximum, 0 is OFF), D: Internal data
setting (0 is “All 0’s”, 1 is “All 1’s”, U is “Counts up” and D is “Counts
down”).
Specified Values: -27.5 to -23.5 dBV
