This test mode allows the power supply to be tested with a special test jig. In this mode, Helix
Under Voltage Fault, Helix Voltage Detected in Standby, and TWT Thermal Fault are masked in
the Transmit state. This test mode may only be selected from the Local panel while the CHPA is
in the Standby state. If the CHPA prime power is lost while HVPS TEST=YES, the CHPA will
power up with no Beam Select and HVPS TEST=NO.
Lines 3 and 4 will appear as follows:
H V P S T E S T M O D E
H V P S T E S T : N O
To select this test mode, press either arrow key to select YES on Line 4. In this test mode, any
meter may be selected. All other CHPA features and controls (aside from the STANDBY and
TRANSMIT button) will be inactive. If a fault occurs, the HVPS TEST will be turned off.
