SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
eNfusion™ HSD-128 High-speed Data Terminal
(c) Operational Verification Tests – Multi-Channel
The operational verification test procedures provided in this section are specific
to Multi-Channel HSD systems and confirm basic system operation.
All verification tests require using the HSD Maintenance Port Utility Program.
1. Verify valid receive (Rx) signals:
With the system powered up, activate Report 23. Confirm that the receive
C/No signal value is greater than 50 dB/Hz as shown in the example below.
2. Verify valid transmit (Tx) signals:
Activate Report 78.
Place a call on the first channel of the Multi-Channel HSD system.
Confirm that the EIRP/Watts values are similar to the examples provided
in
Figure 4–45 and Figure 4–46.
Repeat step b. and c. for each channel installed on the system.
3. Verify Multi-Channel Operation:
Activate Report 78.
Place calls on each channel of the Multi-Channel HSD system.
Confirm that the EIRP values are similar to the examples provided in
Figure 4–47.
