Signal generator has high spectral purity

Rohde and Schwarz has launched a moderately priced signal generator that delivers ultra-pure analogue signals - the SMC100A.

Although it is the smallest instrument in its class, the SMC100A still generates signals of extremely high spectral purity.

All important functions such as AM/FM/fM and pulse modulation are integrated, so no additional options are required.

The SMC100A is suitable for service applications, field use and university labs.

In addition, its short frequency- and level-setting times of <5 ms ensure efficiency in production applications.

The SMC100A is available from 9kHz to 1.1GHz or 3.2GHz.

Compared with other instruments of its class, the compact signal generator (1/2 x 19in, 2HU) has excellent values for single-sideband phase noise (typ - 111 dBc, f = 1GHz, 20kHz offset, 1Hz measurement bandwidth) and broadband noise (typ - 148 dBc).

As a result, users have the opportunity to work with spectrally pure signals in this instrument class.

In addition, test results are not affected by the measuring instrument.

The analogue AM, FM, fM and pulse modulation modes are available as standard.

The frequency range up to maximum 3.2GHz covers applications in the 2.54GHz ISM band as well as EMC requirements.

The high output power of typically greater than +17dBm allows measurements on DUTs that require a high input level.

Attenuation caused by external components such as cables, filters or matching networks can be easily compensated.

In many cases, this eliminates the need for external amplifiers.

The SMC100A is a flexible general-purpose instrument that also achieves top performance in its class when it comes to level accuracy (<0.9dB), as well as frequency- and level-setting times (<5 ms).

For example, if CW signals or signals with analogue modulation are required in the production of keyless entry systems, RFID chips or amateur radios, the SMC100A is the ideal instrument.
