The Model 44A RF wattmeter is a compact, versatile, bi-directional
power measuring instrument used for direct measurement of forward and
reflected power in a coaxial line under any load conditions. Due to the
wide band capability and dynamic range, this instrument does not require
the use of any inserts or bandswitching and covers a power range of 1
to 500 watts. A leather carrying strap is provided to facilitate
portability.
The 20µA taut band meter movement is shock-mounted
in a rugged DIECAST case making this instrument ideal for mobile radio
installation in aircraft or ground vehicles as well as base stations.
The meter movement can be turned off for rough handling when not in use.
The
Model 44AP provides a BNC female RF sampling port with an output 40 dB
below the transmission line level. It allows for injecting an input
signal into the unit under test or can be used for frequency measurement
and spectrum analysis without affecting the operation of the meter.
OPERATION
This instrument has
built-in precision directional detectors which sample forward and
reverse CW power flow in a specially engineered section of transmission
line. The sampled current is scaled to drive the 20µA taut band meter.
Forward and reflected power can be directly measured by rotating the
FWD-REV switch. VSWR is easily determined by comparing these
measurements and using the convenient chart on the back of the
instrument.
Five power scales are provided. The 500 watt scale
will test most high powered transmitters, while the 5 watt scale makes
it simple to tune low powered portable radios. The excellent stability
of this unit and the ability to switch it from one power range to
another to check the calibration eliminates the need for a secondary
standard to verify calibration.
