• IEC bus (IEEE488)

Additional features of URE3

• Peak-value measurement (positive, negative, peak-to-peak)
  without tilts and overshoots
• Fast RMS measurement even of very low-frequency signals
• Frequency measurement up to 30 MHz
• Ultra high measurement accuracy through automatic frequency response correction
• In/out option: dual-channel analog output, ready output, trigger input, TTL frequency counter input

RMS/Peak Voltmeter URE3 further enhances the range of applications due to its greater frequency range and higher accuracy, built-in frequency counter and additional peak-responding rectifier.

Fields of application

• Level measurements in audio range
• Interference measurements on switch-mode power supplies
• Measurement of extremely fast dialing signals and detection of simultaneously transmitted supply voltages in radiotelephony
• Automatic quality control of audio and video tapes
• High-frequency measurements in digital magnetic storage and optical data storage
• Peak weighting in video measurements (sync signals)
• Secondary calibration standard

Measurement accuracy

A patented rectifier circuit with microprocessor-controlled auto calibration makes for the outstanding measurement characteristics of URE2 and URE3. In order to further enhance the accuracy, correction factors are determined for each instrument and measurement range and stored in a nonvolatile memory.
 
A zero function allows noise voltages and the inherent noise to be compensated for, the measurement accuracy being thus increased in particular at low levels.

The measured frequency value is used by URE3 for an internal frequency response correction. This method increases the accuracy mainly at the higher frequencies. Distortion-free measurement of signals is ensured by:

· high input impedance

· low input capacitance

· highpass and lowpass filters that can be switched in to suppress hum or high-frequency noise voltages
