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.

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 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

 Q-peak
 Average detectors
