Operating Instructions
Use and
Function of
Controls
The Model 8135 is a passive electronic device and therefore
has no controls to operate.
Initial
Adjustment
No adjustments or setting are required.
Start Up
Connect the Model 8135 TERMALINE Load to the trans-
mitting equipment under test with 50 ohm coaxial cable
such as RG213/U or equal, and a Male N type plug
(UG-21E/U or equal) which mates with the RF Input con-
nector of the load. After the transmitter has been connected
to the load, proceed according to the transmitter manufac-
turer’s instructions. When reconnecting the antenna, it may
become necessary to readjust the transmitter due to possi-
ble differences in VSWR.
Normal
Operation
Being a passive device, the Model 8135 will function without
an operator in attendance provided its stated performance
limits are not exceeded. WARNING
When power is in the upper range of the load’s capacity, the
radiator will become hot - care should be used in touching
the equipment.
CAUTION
Do not operate this equipment continuously
above the rated 150 W.
Operation
Under
Abnormal
Conditions
The Model 8135 can be subjected to moderate overloads for
short periods of time, providing a sufficient amount of time
is allowed between intervals for adequate cooling. An exam-
ple would be 250 watts for a maximum of 5 minutes, allow-
ing at least a 20 minute interval for cooling between power
applications.
Sutdown
Procedures
There is no way to turn off the Model 8135; power must be
shut off at the RF source instead.
