Rohde & Schwarz URE2-C3

ROHDE & SCHWARZ URE2-C3 

RMS Voltmeter DC - 25MHz IEEE bus, digital readout,
scaleable analog readout URE2 is a broadband RMS voltmeter featuring extremely
high accuracy and speed. A patented rectifier circuit allows measurement of
signals with a crest factor of up to 7 and frequencies of up to 25 MHz.
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.

OPTION C3: Three years of
depot calibration coverage based on the R&S recommended calibration
interval - includes test data. The first calibration is included with product
delivery with 2 additional depot calibration(s).

Fields of application

• Level measurements in audio range
  
• Interference measurements on
  switch-mode power supplies
• Measurement of extremely fast
  dialling 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 autocalibration 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
