The recommended test equipment set-up for the initial checks is shown in
Figure 8.3 on page 134
The operation of the CTU is described in the TBA0STU/TBA0STP
Calibration and Test Unit Operation Manual (MBA-00013-xx).
Important
Ensure that the reciter is configured and calibrated cor-
rectly, and is of the same frequency band as the PA under
test.
When using a desktop power supply to power a 12V PA,
ensure the supply leads are of a suitable gauge to prevent
excess voltage drop. The recommended gauge is 8AWG or
8mm².
Note
If the reciter is fitted with a TaitNet RS-232 system interface
board, connect the PC directly to the reciter (refer to
on page 73).
Note
If the reciter is fitted with a TaitNet Ethernet system interface
board, and the PC is connected to the control panel, run the Serv-
ice Kit and connect to the base station, then power up the base sta-
tion. Refer to TN-1142-AN for full Ethernet connection details.
