Introduction TS9975 system consist of hardware and software controlled by a computer via with a IEEE bus interface. Used for all EMI measurements of conducted and radiated interference. Computer IEEE bus interface Software (EMC32) TS9975 LISN/ current clamp/ absorbing clamp/ probes Antenna Test receiver Conducted emission Radiated emission

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 GHz Input 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 –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  MaxPeak  Q-peak  Average detectors

Antennas HL562 HF
