Once the JetWave™ system is powered up, monitor the “System Available” status discrete. Make

sure that the discrete state agrees with the discrete output in the GUI. Refer to Figure 6-11.

6.4 Cable Calibration

The Modman will not transmit until it has been calibrated, with the transmit cable calibration. After the AES

is physically installed and connected, the Modman will automatically initiate cable calibration during

start-up.

Cable calibration initiates automatically during the initial system commissioning process or after Modman

or KRFU replacement. Cable calibration must be initiated using a GUI commanded test after Tx IF cable

manipulation, connector re-seating and cable replacement.

The transmit cable calibration calibrates the terminal to allow accurate control of transmitter power, taking

into account IF output loss, cable loss, and KRFU (BUC) performance. During calibration, the power amp

of the BUC is disabled.

When calibration is completed successfully, the ACM proceeds to its configured mode of operation as if

it had been restarted. When commissioning is not completed successfully, either due to an error condition

or a user cancellation, the ACM enters an inactive state.

Cable Calibration is available through the GUI Commanded Test - Calibrate Transmit Cable. The Cable

Calibration procedure only takes

up to 15 minutes to perform.

To maintain a fully optimized Jetwave system, it is recommended to perform a single cable calibration in

the 20 year service life, at around 8,000 to 12,000 hours of operation. This optimization will minimize

minor effects of device aging in the transmit chain, and can be performed conveniently using the GUI to
