Environ-
mental
Require-
ments
These wattmeters should be operated in a dust and vibra-
tion free environment. The ambient temperature range
should remain between -40°C and +45°C (-40°F and
+113°F) for proper operation. Allow at least 6 inches (150
mm) of clearance around the units to permit unimpeded
access of natural air convection currents for adequate
heat dissipation.
Items
Furnished
These models consist of a load with a line section/voltme-
ter assembly RF input. The meter assembly is connected
to the voltmeter through a dc cable assembly. This in-
struction book, part number 920-6730B is the only other
item furnished with these models.
Optional
Items
The models 6734B030, 6736-030A, and 6737-030A are
equipped with a special low frequency line section P/N
6734-034. This line section can also be ordered as an op-
tion to convert the models 6734B, 6736A, or 6737A to the
low frequency (-030) version.
Items
Required
A matching connector to the wattmeter is needed on the
coaxial transmission line. Water cooled Models 6737A and
6737-030A must also have a conveniently located water
supply and a drain.
Only simple tools such as screwdrivers will be necessary
for disassembly of this equipment. A resistance bridge or
ohmmeter with an accuracy of at least ± 1% at 50 ohms
is useful for checking the resistance value of the RF sec-
tion assembly.
