When ordering a replacement PCB, use the information in the listed spares drawing to
select the correct assembly (see
page 25,
Interconnection diagrams and listed spares
drawings
).
CAUTION
If this PCB is replaced, ensure that the replacement PCB has the same (or
later) PCB version as the original, that is 07-02029-vv.
NOTE
All input signals for measuring Tx voltages are –10 dBv two-tone signals
from the 0208 test set (or equivalent), unless stated otherwise. This signal
level provides maximum ALC and therefore maximum output power for
taking the measurement.
NOTE
All input signals for measuring Rx voltages are –10 dBm from the RF
signal generator at ±1 kHz from SCF.
