Product Description

This section describes the system components, how to install them, and a brief functional check. For specific power, cooling, and other setup requirements for each component, refer to the manuals for that component.

The Tektronix 27120A EMI Measurement System provides the necessary components to perform precertification and postcertification EMI testing. The EMI measurement system minimizes both EMC laboratory testing cost and testing cycle time prior to applying for final certification. The EMI measurement system is also useful for conducting postcompliance measurements. Postcompliance measurements help to ensure continued compliance with certification standards.

The EMI measurement system includes the following components. For more detailed descriptions of their roles in the system, see the EMI Measurement System Components discussion on page 9.

H Tektronix EMC120 Precompliance Test Software controls testing on the EMI

measurement system. The EMI test software runs under MicrosoftR WindowsR 3.1 or Windows 95R.

H Tektronix 2712 Option 12 Spectrum Analyzer acquires and analyzes the

frequency spectrum of signals present at the RF input.

H Tektronix 2706 RF Stepping Preselector provides a series of bandpass filters

covering successive frequency ranges for the signal input.

H Biconical Antenna provides reception of radiated RF signals over the

frequency range of 20 to 300 MHz.

H Log Periodic Antenna provides reception of radiated RF signals over the

frequency range of 200 to 1000 MHz.

H Non-conductive Tripod provides a sturdy, non-conductive mounting for the

antenna.

H Coaxial Cable provides a flexible 50 W connection between the antenna and

the RF preselector.

H Transient Limiter prevents damage to the sensitive RF input circuitry of the

spectrum analyzer.

H Line IMpedance Stabilization Network couples the conducted emissions

from the equipment under test to the input of the spectrum analyzer.
