The DPM-xx is a single-channel average power meter intended for mm-wave power measurements within 0.01 GHz to 220 GHz band. DPM-xx Power Meter measures absolute power in milliWatts / microWatts or dBm and it also displays set signal frequency in GHz. Easy-to-use operation is ensured by automatic zeroing, automatic recognition of connected sensor and calculation factor table stored in memory for an every sensor.
Compact unit case combined with precise and reliable measurement, plus inexpensive pricing makes DPM-xx Power Meter very attractive to researchers and scientists working in mm-wave labs.
ZBD-series Zero-Biased Detectors (http://www.elva-1.spb.ru/products/microwave/zero-based-detectors.html) are used as power sensors. To cover 0.01 GHz to 220 GHz band, there are a coaxial (0.01-26.5 GHz) and a series of 9 waveguide power sensors (26.5-220 GHz), each of them covering Ka, Q, U, V, E, W, F, D, G sub-band.
Based on Schottky Barrier Diode, the power sensors provide high sensitivity, fast measurement speed, and quicker response to changes of input power. To extend the dynamic range of diode power sensors above their square law region, the correction factor is used. The amplitude and frequency curves for each of individually calibrated power sensor shipped with DPM-xx Power Meter are stored in its EEPROM. The typical curves for amplitude and frequency transfer characteristics for W-band are shown below.
Measured average power will be displayed on 2-line LCD screen with measuring rate of 10 times per second (or faster). For input signals with more than 10mW power, the optional power dividers must be used.
The powermeter has RS-232 port that allows PC controlling and measurement data exchange with the PC. An optional GRIB interface is also available. Upon request you can be provided with a modification of the DPM-xx power meter, that includes two independent measuring channels.

unit can work with different sensors. In other words you can have only one
display unit and set of power sensors for different frequency bands, and
they will work all together. Please mind because ELVA-1 DPM Powermeter is
single-channel powermeter, only one sensor can be used at each moment of
In case you did't entered the valid actual signal frequency when measuring
mm-wave power, the max error will be ±1.5dB for Ka, Q, U, V bands, ±2.0dB
for E, W bands, and ±2.5dB for F and D bands, based on flatness of calibration
Note. In case you did't entered the valid actual signal frequency when measuring mm-wave power, the max error will be ±1.5dB for Ka, Q, U, V bands, ±2.0dB for E, W bands, and ±2.5dB for F and D bands, based on flatness of calibration curves.
