TEST INFORMATION
Tuning procedures
T
1. Turn on the signal generator (f
2. Tune first C50 (multiplier tank circuit), second C11 (RF stage input) to obtain a peak IF voltage at pin FA.
T
1. Make sure that pin DEMO1 is short circuited to ground.
2. Turn on ASK modulation and check that data is appearing on the DATA output pin and proceed with the AC tests.
T
1. Make sure that pins DEMO1 and DEMO2 are connected by the LC tank circuit.
2. Turn on FSK modulation ( f = 10 kHz; RF input level = 103 dBm).
3. Tune C61 (or L60) (phase shifter LC tank circuit) to obtain a peak LF voltage at pin CPC.
4. Check that data is appearing on pin DATA and proceed with the AC tests.
