9. Verifying RF Output
To verify that you have established the correct RF output for the RF OUT
port, follow these steps.
a. Connect an RF OUT port on the modulator to a spectrum analyzer.
b. Verify the output level for the frequency and the channel using a
spectrum analyzer.
c. Repeat steps a and b for the remaining RF OUT port connections.
10. Verifying Audio and Video on a DHCT
After sessions are defined on the DNCS, verify that audio and video are
performing properly on a local Digital Home Communications Terminal
(DHCT).
Quick Reference Guide
Rack Mount Brackets
Use the following diagram to assist you with the installation of the modulator using the supplied notched rack mount brackets.
CAUTION: Take care to install the notched rack mount brackets as shown in the following picture. Inverting the brackets will block
airflow, which will cause the unit to overheat and damage the unit.
