Test receiver (ESIB26)• Test Receiver ESIB26
– EMI test receivers with the large dynamic range required for EMI measurements in conformance with standards.
– ESIB26 (20 Hz to 26.5 GHz) – Frequency range
Input 1: 20 Hz to 26.5 GHzInput 2: 20 Hz to 1 GHz
– Preamplifier with 20 dB gain in conjunction with preselector switch-selectable – Resolution bandwidths
200 Hz, 9 kHz, 120 kHz to CISPR 16-1– Programming
• limit lines• correction factors
– Parallel detectors• Peak (PK)• average (AV)• quasi-peak (QP) • RMS (max.4)

Test reciever (ESPI)• ESPI
– Frequency range 9 kHz to 3 GHz – Fitted with the optional preselector/preamplifier, ESPI models feature
an excellent dynamic range and are therefore able to perform precise interference measurements with pulse repetition frequencies (PRF) from 10 Hz to CISPR 16-1.
– The combination of test receiver and spectrum analyzer – Preselection / 20 dB preamplifier (option) – EMI bandwidths 200 Hz / 9 kHz / 120 kHz / 1 MHz – Programming limit lines and correction factors – Detector
