4-Way RF Amplifier Module
Note: Shunts are available with both red and black tops. Use red to indicate that
power is applied to that port. Use black to indicate that input power is not
applied.

Voltage Check Procedure
Always check both AC and DC voltages during initial setup of the 1.2 GHz GS7000
Node.
Node.
Follow these steps to check AC and DC voltages.
1 Use a true-rms DVM to check for 45 to 90 V AC input voltage at the AC test point
1 Use a true-rms DVM to check for 45 to 90 V AC input voltage at the AC test point
on the power supply module.
