The Signal Generator R&S^® SM300 offers all the features required of a general purpose signal generator: wide frequency range, large variety of modulation functions and high reliability - at an extremely attractive price.

The fields of application of the R&S^® SM300 are virtually unlimited in development, servicing or production where it is used as a flexible signal source in automatic test systems.

The built-in I/Q modulator is ideal for generating digitally modulated signals. An external two-channel arbitrary waveform generator (e.g. R&S^® AMIQ) serves as a modulation source.

 The SM300 is a favourably 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, jM and pulse modulation can be set on the ¸SM300.

The built-in I/Q modulator adds vector modulation capabilities to the ¸SM300. 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.

A clear structure simplifies navigation within the menus.

The high-contrast TFT colour display with 320 × 240 pixel resolution allows traces to be read even at odd angles or when the incidence of light is unfavourable.

• Generation of precise test signals for the following applications:
• lab, service, production and quality assurance
• Provision of digitally modulated signals in the 9 kHz to 3 GHz
• frequency range (e.g. with the ¸AM300 as an external baseband signal source)
• Signal generation and modulation (AM, pulse) for EMC measurements of components (EMS)
• Functionality testing of components in production
• Semi-automatic measurements by pressing a button to retrieve stored settings

• 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

• 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

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 ¸SM300 the ideal tool for use in labs, test sets at colleges and universities, in service and at production sites.

The SM300 is equipped with an I/Q modulator. Together with a baseband source such as the ¸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.

The SM300 can handle all common modulation modes, i.e. AM, FM, jM, pulse. It is used for generating interference signals in EMC applications, e.g. automobile industry, military or avionics.

The USB host interface links the instruments to the PC world. The bus ensures high data transmission rates at low cost. Other peripherals (e.g. printers) can be addressed via another USB interface.

Identical housing

All instruments based on the Family 300 concept have an almost identical “face”, a 5.4-inch VGA TFT display, front-panel control elements, protective guards and a handle that can be adjusted to different positions. Only the connectors on the front and rear panel vary depending on the instrument type.

If the protective guards and the handle are removed, the ¸SM300 can be installed in a 19-inch rack.

All instruments are similarly operated. Most operations are menu-controlled so that no device-specific keys
