Measurement accuracy
A patented rectifier circuit with microprocessor-controlled autocalibration makes for the outstanding measurement characteristics of R&S®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 R&S®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
