Signal generator

20 July 2011 Test & Measurement

The R&S SGS100A, a new signal generator from Rohde & Schwarz, enables production lines to work faster and more cost-effectively. Although much more compact than previous RF sources, it delivers the same performance as high-end conventional instruments.

The new SGS100A signal generator from Rohde & Schwarz covers the frequency range up to 12,75 GHz and has been optimised for use in automated test systems. It fits in just one-half the width of a 19” rack and requires a single height unit. It offers typical frequency and level setting times of 280 μs for high production test throughput.

The instrument provides an output level of typically +22 dBm as standard and has an electronic step attenuator covering the entire frequency range. Its low non-harmonics of –76 dBc up to 1,5 GHz make it a desirable signal source for converter tests.

The SGS100A is available in two models: the CW version generates frequencies up to 12,75 GHz and can be used as a local oscillator as well as for interference testing against mobile radio standards. The vector signal generator version with integrated I/Q modulator offers a maximum frequency of 6 GHz and covers the most important frequency bands for digital communications standards. RF signals from multiple units can optionally be phase-locked to support beam forming applications for the aerospace and defence industry.
