capability. The wide range assures flexibility in coupling medium power amplifier s to oscilloscopes,
voltmeters, power meters, spectrum analyzers and other measuring instruments. The dual directional
design allows the user to monitor both forward and reflected power, a much needed characteristic in
RF susceptibility testing for amplifier overdrive protection, field control and load protection. Low
insertion loss allows efficient coupling to the load.

The Model DC7144A is uniquely suited for use with our “S” series microwave power amplifiers, other
amplifiers operating within this frequency and power range, and our PM2002 power meter.
