About dBm

For over 20 years, dBm has been delivering the state-of-the-art and best-in-class RF link impairment emulation solutions for satellite and non-terrestrial wireless markets. Our link emulation products have the largest worldwide install base spread across 6 continents, have been used in virtually every major satellite system developed since the early 1990s, and are trusted by most major commercial satellite providers, ground station manufacturers and all branches of the US Department of Defense.

The dBm Advanced Channel Emulator (ACE) is the most advanced non-terrestrial RF channel emulation solution to date. The emulated impairments include delay, signal Doppler, attenuation, phase offset, AWGN, frequency hopping, payload and multipath fading. The instrument can house up to four 600 MHz instantaneous bandwidth channels. Impairment emulation can be set to fixed values in Static mode, or continuously changed in real time in Dynamic mode without any phase discontinuities.

Advanced Channel Emulator (ACE) Client is a comprehensive application that enables the remote control of all ACE functions, graphically displays impairment file contents, and provides wizards for creating custom profiles for payload impairments. The ACE Client also enables signal capture, which generates both time and frequency domain plots of the excitation signal, and the output signal after the application of impairments.

dBm’s latest satellite orbit modeling software generates link parameter files formatted specifically for the Advanced Channel Emulator. The new SATGEN offers an enhanced graphical user interface, which easily identifies when transceivers are within the line of sight communication. The transceivers can be programmed to move along a defined path with variable velocity.

dBm’s ACE plug-in for Ansys Systems Tool Kit (STK)⁽ᵀᴹ⁾ provides a control interface between STK and the Advanced Channel Emulator (ACE). Data parameters generated by STK are automatically implemented in the emulator hardware in real time. When operated in dynamic mode, STK is synchronized with the ACE and the dynamic channel parameters are graphically displayed in the STK control interface. The UI Plugin extends the STK⁽ᵀᴹ⁾ Desktop Application’s user interface by adding a custom toolbar, menu, and control window.

Total Quality Management and reliability are at the forefront of our designs and our commitment to quality does not end with the sale of a product. We offer calibration services for every product we produce. Our laboratory is ANSI/NCSL Z540.3 compliant with traceability to the National Institute of Standards and Technology (NIST). All measurement equipment used for final test is maintained on a calibration schedule, and calibrations are performed by independent certified laboratories.

dBm takes extreme pride in the quality and performance of our products. In the unlikely event that your system needs to be repaired, our engineering and quality assurance teams are here to help. We fully support our currently existing product line, in addition to the legacy instrumentation.
