Equipment involved

• Test Receiver• Antenna• LISN• Current Clamp• Absorbing Clamp• Probe set

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

Antennas

• HL562• HF 906• 3160-09

Antenna (HL562)

• HL562– Wide frequency range (30 to 3

000 MHz)– Selectable polarization plane – Gain increase at high frequenc

ies– Polarization linear– Nominal impedance 50 ohm– VSWR typ. <2Max. – RF connector N female

Antenna (HF906)

• Broadband directional antenna– Frequency range1 to 18 GHz– The gain increases with the frequency.– The use of an N connector female– Wide frequency range (1 to 18 GHz)– High gain (7 to 14dB)– Nominal impedance50 – VSWR<1.5 (typ.)
