401-1000 MHz Select for measuring frequencies between 401 and 1000 MHz CAUTION: The Frequency Range is a mandatory parameter setting. The 44D-LXE may not be able to accurately measure the power of a signal if the range is not set correctly. -
Page 13: Specifications
Telewave.io 44D-LXE User Manual Specifications If the 44D-LXE is reading a signal that is outside the range of these specifications, the 44D-LXE will indicate “---” dBm or “0.0” Watts as the measurement. The 44D-LXE is only certified for use on 50 Ω coax-style cables. -

Calibration must be done at Telewave.io, contact Telewave.io sales for a quote. Before each 44D-LXE is calibrated, it will be inspected. A report will be provided detailing any issues found (including a battery health test report.) Any deficiencies found will be repaired (warranty for free, non-warranty if customer authorized) and then the 44D-LXE will be calibrated. -
Page 16: Storage
The 44D-LXE can be stored for long periods in a climate-controlled (cool & dry) environment with no damage. It is recommended to store the 44D-LXE in the TC44-R Case, or it can be wrapped in a cloth and placed into a box or other container. -
Page 17: Appendix: Connecting The 44D-Lxe To The Circuit
When calculating the length of the “Primary” (sometimes called a “Launch”) or “Secondary” cable, subtract 3 inches (7.6 cm) from the length of the cable to allow for the insertion of the 44D-LXE. It is suggested to have one or two test cables built for each band that needs to be tested. For example, a cable built to 159 MHz would cover 144 MHz to 174 MHz. -
Page 18: Lxe Connection Diagram
In this example, the final cut length for the cable would be 19.0 cm (7.5”) If a cable is required after the 44D-LXE to reach back to the feed line, that cable should be built to the same specifications as the “Primary” or “Launch” cable. -
Page 19: Appendix: Rf Sample Port Isolation
The Sample Port is passive and has a usable bandwidth from 30 to 960 MHz. The active components of the 44D-LXE have a narrower bandwidth of 118 to 960 MHz. The isolation provided by the sample port is consistent at 50 dB +/- 2 dB from 200 MHz up to 960 MHz (the highest frequency supported by the 44D-LXE.)
