The Rohde & Schwarz SM300 Vector Signal Generator for Analog/Digital Modulations is a favorably priced signal generator for applications in the 9 kHz to 3 GHz frequency range. The instrument features a broad scope of functions, outstanding technical characteristics and compact design. The analog modulation modes AM, FM, φM and pulse modulation can be set on the Rohde & Schwarz SM300. The built-in I/Q modulator adds vector modulation capabilities to the  Rohde & SchwarzSM300. Digitally modulated signals can thus be generated, as required in mobile radio, for example. The ̧SM300 offers an immense range of applications – whether on the lab bench, in service or as a flexible measuring instrument in automatic production systems.

• Vector Modulation:
  • High I/Q bandwidth (DC to 40 MHz) for WLAN measurements in accordance with IEEE 802.11b and IEEE 802.11g
  • Generation of WCDMA test signals for measuring ACLR, EVM and code domain power
    • ACLR WCDMA 3GPP FDD (test model 1, 64 DPCHs)
    • Offset 5 MHz: typ. 54 dB
    • Offset 10 MHz: typ. 55 dB
    • Composite EVM (test model 1, 64 DPCHs): typ. 3.3 %
  • Generation of GSM signals for measuring phase error
  • Phase error: typ. 1.2° rms
• EMC (Electromagnetic Compliance)
  • Provision of signal generator control level in 20 Hz to 3.0 GHz frequency range
  • AM, pulse modulation modes
  • Internal pulse generator
  • EN61000-4-3/6 standards; MIL-STD-461E, ISO 11451 and ISO 11452, each up to 3 GHz
• High signal quality
  • The RF characteristics of the ̧SM300 set new standards in the lower price segment. With a frequency range from 9 kHz to 3 GHz, it is suitable for diverse applications. Its low wideband and single-sideband phase noise make the Rohde & Schwarz SM300 the ideal tool for use in labs, test sets at colleges and universities, in service and at production sites.
• Built-in I/Q modulator:
  • The Rohde & Schwarz SM300 is equipped with an I/Q modulator. Together with a baseband source such as the Rohde & Schwarz AM300, it can thus generate complexly modulated signals. Applications in mobile radio are also possible, for example for GSM, 3GPP or IEEE 802.11b and IEEE 802.11g.
• Wide variety of analog modulation modes:
  • The Rohde & Schwarz SM300 can handle all common modulation modes, i.e. AM, FM, φM, pulse. It is used for generating interference signals in EMC applications, e.g. automobile industry, military or avionics
• Frequency sweep, level sweep:
  • The R&S SM300 makes it possible to sweep the internal LF generator as well as the RF frequency and the RF level in user-selectable steps.

• Frequency range: RF: 9 kHz to 3 GHz, LF: 20 Hz to 80 kHz
• Frequency resolution: 0.1 Hz
• Frequency setting time: <10 ms
• Modulation modes: AM/FM/φM/pulse/IQ
• Level resolution:0.1 dB
• Level uncertainty: <1 dB (for levels >–120 dBm)
• Level range: –127 dBm to +13 dBm
• Level setting time: <200 ms
• Single-sideband (SSB) phase noise:<–95 dBc (1 Hz) (at f = 1 GHz,∆f = 20 kHz)
• Internal modulation generator: 20 Hz to 80 kHz
