test signal 1;
−
P1 = −30 dBm
(minimum Pmax)
BER ≤ 3 × 10−2
(e.g. 7.5 bit errors per second for 250 bits/s)
test signal 1;
P1 = Pref + 10 dB
test signal 3;
P1 = −50 dBm
test signal 3;
P1 = −50 dBm
−
test signal 3;
P11 = −70 dBm;
P12 = −38 dBm
(minimum P1dB)
−
check that the first 10 bits are correct; error counting is
started 10 ms after VCC is switched on
test
IP3 = P1 + 1⁄2 × IM3 (dB);
signal 2; minimum value: IP3mix ≥ −20 dBm
P2 = P1
test
IP3 = P1 + 1⁄2 × IM3 (dB);
signal 2; minimum value: IP3IF ≥ −38 dBm
P2 = P1
−
no spurious radiation (25 MHz to 1 GHz) with level
higher than −60 dBm (maximum Pspur)
−
(Po1 + 70 dB) − [Po2 + 38 dB (minimum P1dB)] ≤ 1 dB,
where Po1 is the output power for test signal with P11
and Po2 is the output power for test signal with P12
Notes
1. The supply voltage VCC of the test circuit alternates between ‘on’ (100 ms) and ‘off’ (100 ms); see Fig.3.
2. Differential probe of spectrum analyser connected to pins MOP and MON.
3. Probe of spectrum analyser connected to pin LIN.
4. Spectrum analyser connected to the input of the test board.
5. Probe of spectrum analyser connected to either pin MOP or pin MON.
