TEST INFORMATION
Tuning procedure for AC tests

3.
4.
Turn on the signal generator (f
i
= 433.92 MHz; no modulation; RF input level =
60 dBm).
Tune C6 (RF stage input) to obtain a peak voltage on test point A (see Fig.11).
Turn on modulation (f
i
= 433.92 MHz; f
mod
= 250 Hz square wave;
f = 25 kHz; RF input level =
60 dBm).
Check that data is appearing on the data output (pin 11) and proceed with the AC tests.
AC test conditions

The reference signal level P
ref
for the following tests is defined as the minimum input level in dBm to give a
BER
≤

(e.g. 15 bit errors per second for 500 bits/s).
Test signals
Table 3
P
1
is the maximum available power from signal generator 1 at the input of the test board; P
2
is the maximum available
power from signal generator 2 at the input of the test board.
