Microwave radiation and leakage meter
1 Scope
This procedure is applied for the first time in the operating frequency range of 915MHz ~ 18GHz microwave radiation leakage and measuring instrument
Test, test and subsequent use of checks.
2 Overview
Microwave radiation and leakage meter is used to measure radiation and microwave equipment microwave energy leaking to the space instruments.
Microwave probe of the electromagnetic field sensitive element, can be directly converted microwave signal into a DC signal, the indicator value.
3 metering performance requirements
Frequency range. 915MHz ~ 18GHz;
Power density measurement range. (0 ~ 3) mW/cm2;
Power density measurement maximum permissible error. ± 2.75dB.
4 General technical requirements
It should be the subject instrument manufacturer, instrument name, instrument model, serial number and power requirements information. Microwave radiation
And leakage measurement instrument control buttons, key switch, input and output ports should be clearly marked, and having a metering device
A manufacturing license logo.
There should be no prejudice to the subject instrument readings and affect the normal mechanical damage, control knobs and buttons should be able to work properly
For the display to show, all kinds of signs should be clear and complete; pointer instrument gauge needles should bend, mechanical meter
Zero can be adjusted freely.
5 control of measuring instruments
Controls include initial verification of measuring instruments, verification and subsequent use of checks.
5.1 verification Conditions
5.1.1 Environmental conditions
1) Ambient temperature. (23 ± 5) ℃.
2) Relative Humidity. 20% to 80%.
3) Power supply voltage and frequency. (220 ± 11) V, (50 ± 1) Hz.
4) The laboratory shall be no severe impact and vibration measurements of electromagnetic interference.
5.1.2 The test equipment
5.1.2.1 power density means the overall requirements of the standard
Frequency range. 915MHz ~ 18GHz;
