Directional Wattmeters

The high-precision THRULINE Model 43 wattmeter inserts between the transmitter and load and measures forward or reflected power in coaxial transmission lines under any load condition. Optional plug-in elements determine the power rating and frequency range. Simply rotate the element to read forward or reflected power. The model is a shock-mounted meter with 25, 50 and 100 scales, permitting full-scale power reading from 100 mW to 10,000 W with the appropriate element installed. It has type N connectors and a frequency range of 450 Khz – 2.7 Ghz, depending on the element.

The THRULINE Model APM-16 average reading meter was designed for measuring digital and complex waveforms used in PCS, cellular and other digitally encoded services. It enables precise average power readings for both digital and analog systems. The model has a frequency range of 2 Mhz – 2.3 Ghz and a power range from less than 1 W to 1000 W with the appropriate element installed.
