Testing The Chpa Via Computer Control - CPI 0102324500rR Manual

CHPA S
ERIES
d. Once the CHPA is in the Transmit state, the High RF Fault will be detected and steps a
through c will occur two more times before the CHPA latches into the Fault state.
e. Once the CHPA is latched into the Fault state, the FAULT LED will flash.
9. Adjust the attenuator setting to the setting noted in step 6.
10. Press the CANCEL pushbutton and adjust the unit RF power. The FAULT LED will go off.
The CHPA will then transition to the Standby state and the STANDBY LED will light.
11. If no options are to be tested, switch off the main power to the CHPA, remove the RF Input
and Output test loads, and make the normal RF Input and RF Output connections.
This completes the initial power-on and checkout procedure. If the CHPA is to be computer
controlled, use the following procedure. Also, check any optional equipment at this time such
as the Remote control panel and/or integral linearizer.
THE CHPA IS NOW READY FOR NORMAL OPERATION. (Refer to Chapter 5 for normal
operating procedures.)

Testing the CHPA via Computer Control

If the CHPA is to be controlled by a computer, perform the following steps:
1. Verify that the customer computer contains the software to drive the CHPA.
2. Verify that the customer computer is connected to the serial Computer Interface (CIF)
connector located on the CHPA back panel.
3. Verify that the CHPA is powered on and in Standby as indicated by the STANDBY LED
being lit.
4. Verify that the CHPA CIF serial port parameters have been set to match the computer
system to be used. These parameters are listed in Table 4-5. (Refer to "Setting the Serial Port
Parameters" for procedure.)
5. Press the LCL/RMT pushbutton until CIF shows in the upper left corner of the display.
(This indicates that the computer can now control the CHPA.)
6. Perform tests at the computer to confirm that it not only has complete control of the CHPA
but that it has complete monitoring capabilities of all of the metering available on the CHPA
front panel.
7. If no options are to be tested, switch off the main power to the CHPA, remove the RF Input
and Output test loads, and make the normal RF Input and RF Output connections.
