ELVA-1 has updated its DPM series of microwave and millimeter-wave power meters with a new touchscreen-based control and display unit, designed to simplify operation and improve usability in laboratory and development environments. The update introduces a revised user interface while retaining the underlying measurement architecture.
The DPM series supports power measurements from 10 MHz to 220 GHz, covering multiple frequency bands with high sensitivity and a dynamic range of up to 50 dB. These instruments are intended for use in mm-wave test setups, telecommunications and radar research, and other applications requiring accurate power evaluation.
Measured power is displayed in milliwatts, microwatts, or dBm, together with the user-defined signal frequency. Automatic zeroing, sensor identification, and calibration data stored within each sensor reduce setup effort and minimize configuration errors. The modular architecture allows the control unit and sensor heads to be used flexibly in both bench-top and portable measurement scenarios.
User Interface Update
The revised control/display unit enables direct interaction through a touchscreen. Measurement functions are arranged to provide clear separation between frequency entry, power readout, and system controls, allowing parameter changes without interrupting active measurements. Frequency values can be adjusted using on-screen arrows, a numeric keypad, or an encoder-style input. The active digit is visually highlighted to support precise tuning during setup and testing.
Measurement Display
A real-time graphical view shows recently acquired power values, with new samples added continuously. This allows users to observe signal trends and variations during alignment or measurement procedures. Display settings such as reference level, vertical range, update speed, and autoscaling can be configured. Auto scale operation automatically adjusts the display to accommodate changing signal levels.
Data Storage and Export
Measurement results can be saved as single values or continuous datasets in a tab-separated text format. Stored data is accessible through the built-in web interface, enabling straightforward transfer to external systems for analysis or documentation.
They are commonly used in mm-wave test benches, telecommunications and radar research, and scientific measurement systems where reliable power evaluation is required.
