3.7 Verify RF Output
If you want to verify RF output levels, connect a power meter to J4
before you power-up the amplifier. Proceed as follows:
a. Verify that the amplifier output is terminated with a RF
Load capable of dissipating full rated output.
b. Verify that no RF drive is applied to the amplifier input.
c. Verify that the amplifier is in the STANDBY state (amplifier
Yellow STBY LED lighted), Remote Control Unit STANDBY
LED lighted, and display reads. “
REMOTE STANDBY
”.
NOTE: Pressing TRANSMIT in the REMOTE mode is equivalent to
setting the amplifier HV ON/OFF switch to ON in the LOCAL mode.
d. Press TRANSMIT.
The TRANSMIT LED will blink while the amplifier goes
through the Beam On Sequence (BONS). The display will
read “
REMOTE BEAM ON SEQ
”.
When BONS is complete, the TRANSMIT LED will stop
blinking and remain lighted (Green). The display will read
“
REMOTE RF OUT 0W”.
e. Starting at –40 dBm, slowly increase RF drive until rated
output power is achieved. Shut off RF input.
f. Press STANDBY.
The amplifier should go to the STANDBY mode.
