3.8 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:
1. Verify that the amplifier output is terminated with a RF Load capable of dissipating full
rated output.
2. Verify that no RF drive is applied to the amplifier input.
3. 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.
4. 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”.
5. Starting at –40 dBm, slowly increase RF drive until rated output power is achieved. Shut
off RF input.
6. Press
STANDBY.
The amplifier should go to the STANDBY mode.
