Description
Set the CHPA RF output power.
Set the attenuator setting. If the entry in dB
CHPA is in ALC RF Power mode, a direct
attenuator setting will cause the CHPA to
return to Open Loop RF Power mode.
Set the RF Power mode. ALC (Automatic
Loop Control) RF Power mode will hold the
RF output power to the specified output
power within the range of the attenuator and
the RF output capabilities of the CHPA. If
ALC mode is chosen, ALC is displayed on
Line 1 of the display. If ALC mode is chosen
while the unit is in Standby, the attenuator
will be set to maximum attenuation. Open
Loop sets the RF output to the requested RF
power level, after which no further control is
exercised.
Inhibit RF.
All RF readings (meters, alarm/fault trip
settings, RF Out setting) are affected by this
setting. When an RF setting/meter is 0 W,
the dB display should change to indicate 0
W. If RF Display = dBm or dBW, the user
will enter 0 W by first pressing the decimal
point button and then 0 followed by ENTER.
If Yes is selected, the RF Monitor board
cannot enter Peak Detect mode.
