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.
