Description: BROADBAND RF WATT METER
Information:
                                    This manual provides the physical and functional description and
operating theory necessary for effective use of the Telewave
Model
44L1/L1P Broadband Radio Frequency (RF) Wattmeter. Its features
include:
• Displays five power ranges
• Measures 1 to 500 watts
• Does not require inserts
• Does not require band switching
• Fully operable in freezing conditions
• Provides 5 watts full scale range
• Interchangeable connectors (QC)
• Lighweight, rugged and easy to carry
• -40 dB RF sampling port (Model 44L1P)

2.02 The instrument integrates two broadband directional
couplers for measuring incident and reflected power,
ranging, calibration and display. The wide coverage and
dynamic range of this instrument eliminates any inserts or
band switching. A 20 uA taut band meter movement is used to
display the measured power, providing the
measurement accuracy necessary to tune low power portable
transmitters.

2.03 A convenient, easy to read, voltage standing wave ratio
(VSWR) chart is provided on the rear of the instrument for
determining VSWR from the measured incident and reflected
power levels. The instrument is designed for rugged field
use and is housed in a diecast metal case with a leather
carrying strap. The measurement circuits
in the wattmeter are driven directly by the current
developed in the coupler, making it unnecessary to supply AC
power or batteries. A carrying case (Model TC44) is
available as an option. The Model
44L1/L1P is ideally suited for mobile, marine, and aircraft
applications as well as base stations.
