URE2 Shown
|
| |
| 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.
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
