3-4 WARNINGS
The system provides warnings for the following
operating conditions, which are considered
detrimental to the proper functioning of the
analyzer:
RF Overload
(Input level to monitor too great for accurate
measurement)
Recalibrate
(Indicates that the unit's internal temperature
has changed more than 10º C from where it was
last self-calibrated. This may affect the
accuracy of the generator output level, monitor
input level below +20 dBm, and modulation
level. Refer to paragraph 3-8.3 for further
information.
RF Overtemperature
(Excessive power to RF load)
Optional Battery Pack Voltage Low
If any of these conditions exist:
A warning will be displayed on the warning
line of the LCD for RF overload, recalibrate,
and low battery voltage.
A continuous audible warning tone along with
an overwrite of the screen with a warning
message will be presented for RF overtemper-
ature (figure 3-3). This condition may occur
when the intermittent power rating of the 125
watt internal load is exceeded. Both the display
and the warning tone remain on and all opera-
tor input is ignored until the condition is corre-
cted. The Analyzer then resumes normal oper-
ation.
CAUTION
Remove RF power immediately to correct
the RF overtemperature condition. Oth-
erwise damage to the unit may occur.
