The Power Sensor is designed for conversion of the built-in detector output voltage into digital signal proportional to the input power.


The Power Meter consists of the diode power sensor and the Indicator Unit or a personal computer with a virtual panel.

Using a diode Power Sensor instead of a conventional thermal converter provides inertia less power conversion system, which allows to integrate the instrument into automated systems.

Possibility of reliable low level power measurement allows to design microwave frequency paths with low level operating signals levels thanks to using low-barrier diodes.

Power Sensor is based on 0.01 to 26.5 GHz frequency range coaxial detector set and

18 GHz to 178 GHz waveguide detector set.


Frequency range: 0.02–17.85 GHz

Input power range: from –50 dBm to +20 dBm

Basic power measurement accuracy: not more than ±5 %

Complementary measurement error at ambient temperature change not more than ±1 %

The Instrument is powered from a PC USB-port

Dimensions: 130х40х30 mm

Weight: 150 g

The Institute of Electronic Measurements KVARZ can develop and manufacture power meters in accordance with customer’s requirements in the following frequency ranges:

0.02–18 GHz; 0.01–26.5 GHz;

18–26 GHz; 26–40 GHz;

40–60 GHz; 50–75 GHz; 75–110 GHz;

110–170 GHz

The Instrument input power range may be also extended up to 1 and 10 V.
