Introduction
The rules of order within the frequency range of 2GHz RF voltmeter test method is JJG 279-1981
"WFG-1B high-frequency micro-volt meter", JJG 308-1983 "UHF millivoltmeter" and JJG 319-1983 "UHF
Microvolt table "revision. These three test procedures have been implemented for 20 years. With the radio measurement technology continues
Development, radio voltage measurement mode has also been greatly improved and changed. In particular digital voltmeter has gradually
Replace the low-frequency electronic voltmeter measuring, electronic voltmeter low frequency range has also been extended to the ultra-high frequency band.
Thus, the old regulations on certain technical requirements for the practical requirements of today has been incompatible. Prepared on the basis of this Regulation
JJF1002-2010 "national verification procedures writing rules" and JJF1059 "Evaluation and Expression of Uncertainty in Measurement"
carry out. In the revision, extension of the original protocol of the frequency range and voltage range, has been adapted to the current actual RF voltmeter
Verification requirements.
RF voltage meter testing procedures
1 Scope
The order applies to frequencies within the range of 2GHz, the voltage measurement range of RF power 300μV ~ 100V
Pressure gauge (hereinafter referred to as voltmeter) initial verification, use and subsequent verification check.
2 Overview
RF voltmeter is an important measurement of radio instruments. Usually by the detector, dividers, amplifiers and indicators
constitute. After the detector RF signal detector, DC amplifier for DC signal detection after amplification, and then by the finger
Indicator indicating voltage values measured. Widely used in measuring radio and working conditions of electronic circuits or components. Xu
Multi-parameter measuring instrument basis.
3 metering performance requirements
3.1 voltage basic error
Voltage basic error. ± 3% (100kHz).
3.2 Additional frequency error
Additional frequency error.
± 3% (100kHz ~ 50MHz, ≥10mV);
± 5% (20kHz ~ 200MHz, ≥3mV);
± 15% (20kHz ~ 1GHz, ≥3mV);
± 20% (10kHz ~ 2GHz, ≥1mV).
When the test subject to be seized equipment technical indicators.
4 General technical requirements
4.1 Visual inspection
Voltmeter should have a factory, instrument name, instrument model, serial number and power requirements. Control voltmeter
Knob, key switch, input and output ports should be clearly marked.
4.2 Functional Check
Before being energized there should be no prejudice to the subject voltmeter readings and affect the normal mechanical damage, control knobs and buttons should
To work properly, the display to show, all kinds of signs should be clear and complete; pointer instrument gauge needles should bend,
Header mechanical zero can be adjusted freely and so on.
4.3 energizing check
After being seized voltmeter energized preheated pointer instrument should be able to adjust the electrical zero and from school. Added signal table
Head should be indicative and not jammed and jumping phenomenon.
