DPS-100D Digital RF Power Measurement System


The DPS-100D Digital RF Power Measurement System includes a precision directional coupler ordered by EIA line size, and DPS-100D Digital RF power meter electronics package with onboard backlit LCD display. This system is suitable for measuring analog or digital RF signals with accuracy within +/- 5% of reading. Use the DPS-100D as a stand alone power monitor/antenna protection system or use more than one DPS-100D to create a monitor system for master antenna applications or for complete RF facility site monitoring. The DPS-100D is part of a larger family of site monitoring products available from Broadcast Devices, Inc.




Simultaneous Forward/Reflected Power Indication, Onboard Backlit LCD Display with proprietary 3 strike protection system for sustained high VSWR conditions, Onboard Web Server for remote interrogation of parameters, Transmission Line Surface Temperature Indication – Second Temperature Sensor input available* - Transmission Line , Pressure indication**Phantom Powered RS-485 Communications bus for easy interconnection of other sensors using industry standard category 5 cabling or SWP series supervisory chassis available from BDI - Operate standalone or part of a larger system with up to 255 additional DPS-100D sensors Analog 0-5 VDC scaled outputs of power indication for remote control input, 8 Programmable General Purpose inputs for interlock lock out tag out status, remote reset etc.


  • 2 – Form C programmable relays for interlock and alarm indication
  • * Second temperature indication requires the use of BDI P/N TMP-100 temperature sensor
  • ** Requires use of the BDI P/N PSW-100 pressure sensor and requires a suitable gas termination such as the ERI gas barrier assemblies. These gas barrier assemblies are available in many line sizes including 1-5/8”, 3-1/8”, 4-1/6”, 6-1/8”, 8-3/16” and 9” EIA transmission line sizes.
