Used Rohde & Schwarz ESMI EMI Test Receiver, 20Hz to 26.5Ghz

Product Highlights

The ESMI is a 26.5 GHz receiver from Rohde & Schwarz. Engineers use electromagnetic interference (EMI) receivers during compliance regulation testing. An EMI receiver is a device that can measure several different characteristics of radio signals as well as calibrate radiofrequency (RF) attenuators and signal generators.

• Frequency range: 20 Hz to 26.5 GHz, up to 110 GHz with external mixers
• Resolution: 1Hz
• Frequency Scale: selectable LIN/LOG
• Frequency span: 10 Hz to 2/5 .2/26 .5 GHz
• RF attenuation switchable in wide range and small steps
• Refined preselection
• Very large frequency range for EMI measurements
• Low-noise preamplifier with wide dynamic range
• High-level mixer for IF conversion
• Additional filters ahead of IF preamplifier to avoid overloading due to broadband interference in IF section
• Highly linear envelope detector with dynamic range of 70 dBm in addition to 110 dB logarithmic convertor in analyzer path
• Five parallel detectors for peak, minimum, quasi-peak, average and RMS weighting
• DC logarithmic convertor with dynamic range of 70 dB
• Overload detectors at the mixers and in the test channel to avoid incorrect measurements
