The R&S®ESR is an EMI test receiver for the frequency range from 10Hz to 7GHz and complies with the CISPR 16-1-1 standard. It can also be used for diagnostic measurements during development and for use with precompliance measurements to prepare products for certification testing.
The ESR7 measures electromagnetic disturbances from 10Hz to 7GHz, it uses either conventional stepped frequency scan or an FFT-based time domain scan, a method that significantly speeds up measurements. The ESR7 is also a full featured, signal and spectrum analyser for lab applications.
The ESR7 comes with functions such as IF analysis for displaying the spectrum around disturbance signals, or spectrogram display in the analyser mode, to help users analyse disturbance signals. The instrument can simultaneously display up to six different traces on its 8.4" touchscreen for fast effective result analysis.
