NATIONAL STANDARD OF THE UNIT OF POWER OF ELECTROMAGNETIC OSCILLATIONS (37.5 – 178.4 GHz)
|
|
|
|
PURPOSE
Reproducing, maintaining, and transferring the value of the unit of power of electromagnetic oscillations in the frequency range from 37.5 to 178.4 GHz. This standard is included in the State Register of National Measurement Standards of the Republic of Belarus (NS RB 69-25).
APPLICATION
Research, adjustment, verification, and calibration of absorbed and transmitted power meters in the super-high-frequency range used in infocommunications, radioelectronics, radar systems, and instrument engineering.
DESCRIPTION
The standard enables automated measurements of the power unit in waveguide paths in four subranges:
- from 37.5 to 53.57 GHz
- from 53.57 to 78.33 GHz
- from 78.33 to 118.1 GHz
- from 118.1 to 178.4 GHz
The principle of operation of the standard is based on the method of substituting microwave power with direct-current power.
THE STANDARD INCLUDES
- sets of calibration devices, signal generators, and absorption power meters in four frequency subranges;
- a PC with specialized software.
