Rohde & Schwarz URE3 RMS/Peak Voltmeter

The Rohde Schwarz URE3 is a fast high accuracy bench voltmeter for true RMS and peak voltage measurement. It builds on the earlier URE2 with a greater frequency range, higher accuracy, a built in frequency counter, and an additional peak responding rectifier. It suits R&D labs, production test, and calibration work where precise AC measurements matter

Key Features

True RMS measurement: for both AC and AC+DC signals
Peak-value measurement: positive, negative, and peak to peak
Wide frequency coverage: from 0.02 Hz up to 30 MHz with a built in frequency counter
Autocalibrating rectifier: a patented rectifier circuit with microprocessor controlled autocalibration with correction factors stored for each instrument and range
Automatic frequency response correction: the measured frequency is used to correct the frequency response internally
Zero function: compensates for noise voltages and inherent noise improving accuracy at low levels
Fast readings: more than 30 measurements per second
Filters and displays: highpass and lowpass filters plus digital and analog displays
Analysis tools: relative measurements and maxima/minima
Connectivity: IEC/IEEE bus control of all functions with an optional IN/OUT interface offering dual channel analog output, ready output, trigger input, and a TTL frequency counter input

Typical Applications

Level measurements in the audio range
Interference measurements on switch mode power supplies
Measuring very fast dialling signals and detecting superimposed supply voltages in radiotelephony
Automatic quality control of audio and video tapes
High frequency measurements in digital magnetic and optical data storage
Peak weighting of video sync signals
Use as a secondary calibration standard

Why Choose It

The Rohde Schwarz URE3 combines true RMS accuracy, peak detection, and frequency measurement in one instrument replacing several separate meters on the bench. Its autocalibration and frequency response correction make it dependable for demanding measurements, and the IEEE bus makes it easy to integrate into automated test systems.
