Application
Because the SM300 of R&S has numerous function, so it is the ideal instrument in different applying, word of example exactly the number and imitate are wireless communication or EMC.
Accurate test signal generates in following applying:
Lab, service, production and quality assure
* arrives in 9KHz 3GHz frequency paragraph inside provide digital modulation signal (for example, use R&SAMIQ to regard signal of exterior base band as the source)
The EMC that * is yuan of parts of an apparatus is measured (EMS) generation signal and modulation (AM, pulse)
* production is medium the function of yuan of parts of an apparatus checks
The setting that * calls memory through key-press will come true semi-automatic measure
Vector signature is made
Bandwidth of * tall IQ, the W-LAN that applies to IEEE 802.11b and regulation of IEEE 802.11g place measures generation WCDMA to check signal, with will measure ACLR, EVM and code region power
*ACLR WCDMA3GPP FDD (64 DPCH channel)
Deviate 5 MHz: - 54 DBc Typ.
Deviate 10 MHz: - 55 DBc Typ.
Synthesize EVM (64 DPCH channel) : 3.3% Typ.
* generates GSM signal, use at measuring phasic error phasic error: 1.2°rms model is worth
EMC
* makes 20 Hz control n to what signal source provides inside the frequency limits of 3 GHz
*AM, pulse moves patternmaking style
* in-house clock
*EN61000-4-36 standard; MIL-STD-461E, ISO 11451, with ISO 11452, avery kind of can achieve 3 GH
Believe number quality high
The radio frequency character of R&SSM300 established new standard in the instrument of low price. Its low broadband and unilateral take phasic noise to make R&S SM300 makes application at the lab, the test device of institute and university, serve and manufacture the ideal tool of the spot.
Use at the in-house IQ modulator of base band signal
In-house IQ modulator expanded the application of R&S SM300 wireless communication domain, make thereby use at GSM, 3GPP or IEEE802.11b, the modulation of vector of base band signal of G becomes a possibility.
Imitate moves the diversity of patternmaking type
R&SSM300 can handle mode of all imitate modulation: AMFMΨM pulse modulation, it can use generation to disturb signal, for example auto industry, military affairs, aviation, or commerce is measured.
Frequency scanning, n scanning
R&SSM300 can undertake the scanning of source of in-house low frequency, still can enter with the pace of user make choice of undertake radio frequency frequency and n scan.
