GMW-25

4.3

Analog Remote Interface Faults

If the unit is connected to a test fixture, such as ENI’s UTF-10, two
more faults can be detected. One is indicator driven (also known as a
“Hard Fault”) and the other appears on the display (also known as a
“Soft Fault”).

4.3.1

RF OVERHEAT (Hard Fault)

This fault occurs when the RF temperature is above the limit. The RF
OVERHEAT lamp will light up on the front panel of the test fixture.

4.3.2

MAX POWER (Soft Fault)

This fault occurs when the maximum power limit has been reached.
The message will appear on the digital readout of the test fixture.
