Features
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.
Ergonomic user interface
Operation is menu-guided so that even untrained users will quickly obtain correct results.
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.
Applications
Its broad scope of functions makes the SM300 the ideal instrument for diverse use, e.g. in digital and analog mobile radio or for EMC applications.
- 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
Vector modulation
EMC
-
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 ¸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 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.
Wide variety of analog modulation modes
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.
Frequency sweep, level sweep
The ¸SM300 makes it possible to sweep the internal LF generator as well as
the RF frequency and the RF level in user-selectable steps.
USB interfaces
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.
Owing to their slim design, two instruments of the Family 300 can be placed next to each other.
Uniform operating concept
All instruments are similarly operated. Most operations are menu-controlled so that no device-specific keys
are required. Only the four unit keys for entry confirmation are configured separately.
