R&S®TS8996 RSE Test System
Fully automatic emission measurements on wireless communication equipment
Specified spurious emission measurements
The relevant standards stipulate a wide variety of measurements in a very wide frequency range, all of which can be covered with TS8996 e.g.
- Frequency range 30 MHz to 18 (40) GHz
- Measurements according to standards ETSI EN 301489,FCC part 15
- Conducted spurious emission measurements from 100 kHz to 12.75 GHz on antenna connector of DUT
- Measurement of spurious emissions from radiocommunication equipment
For some radiocommunication systems (eg short-range devices), higher frequency limits (eg 40 GHz) are already stipulated for spurious emission measurements. TS8996 can be easily adopted accordingly to accommodate the customer requirements.
Spurious emission measurements differ from EMI measurements to EN55022 mainly in that bandwidths matching the useful signal have to be set on the receiver instead of the typical EMC bandwidths (eg 200 Hz, 9 kHz, 120 kHz). It should also be noted that EMC bandwidths are referred to the 6 dB points of the IF filters, whereas the bandwidths for spurious emission measurements are referred to the 3 dB points. In spurious emission measurements, the peak detector takes the place of the quasipeak detector. All these differences make it necessary that for spurious emission measurements a spectrum analyzer or test receiver with spectrum analyzer functionality be used rather than a pure EMC test receiver.
