3-3 Initial Start-Up and Operating Procedures
To perform the initial start-up, proceed as follows:
• Double check to ensure that all input and output cables are properly connected.
C
AUTION
Before applying power, make sure that the input and output of the amplifiers are prop-
erly terminated at 50 ohms. Do not operate the amplifier without a load attached. Re-
fer to Table 1-1 for input power requirements. Excessive input power may damage
the MCPA.
N
OTE
The output coaxial cable between the amplifier and the antenna must be 50 ohm co-
axial cable. Use of any other cable will distort the output.
• Place the power ON/OFF switch on the MHUI front panel in the “ON” position.
• Allow the amplifiers to warm up for at least 5 minutes before taking power readings.
• Refer to Appendix A for the power setting procedure.
