The Telewave 44D digital wattmeter is similar in size and look to its predecessor the 44A (analog wattmeter), but this compact and versatile instrument has many more capabilities. The meter is connected inline and is able to test the power output of a transmitter and the health of the antenna. It can measure signals modulated with a variety of analog and digital schemes including: CW, AM, FM, P25-1&2, DMR/d-PMR, IDAS/NXDN, D-Star, Fusion, Tetra, PTC, and more.

Feature highlights include:

  • Broadband frequency coverage from 88 MHz to 1 GHz
  • Dynamic forward power range from 1 to 500 watts
  • Measurement accuracy of ±6% (no band “elements” or lookup tables)
  • Simultaneous display of forward and reverse power (selectable display in watts or dBm)
  • Selectable display of average or peak power
  • Real-time calculation of VSWR or Return Loss (selectable in the display)
  • Real-time calculation of Crest Factor

The metal case provides ingress protection equivalent to IP54 while also shielding against the occasional short drop or bump as the meter is moved around the work site. The display screen has an adjustable brightness backlight and is easy to read in any ambient light level. The bi-directional RF sampling port provides 50 dB of isolation between the transmission line and any connected signal injection or monitoring test equipment.
