MUNICH – Rohde & Schwarz in Munich is introducing the R&S SMA100B analog signal generator with a frequency range to 20 GHz for defense, aerospace, RF semiconductor, and wireless communications test and measurement applications.
The device delivers signals with low phase noise and high output power with low harmonics. Engineers no longer need to compromise between output power and a spurious free dynamic range, company officials say.
A 6 GHz instrument generates to 38 dBm RF output power, and a 20 GHz instrument generates to 32 dBm in the microwave frequency range. Harmonics are low across the frequency range; above 6 GHz they are even lower than 70 dBc at 18 dBm output power. Nonharmonics are below 110 dBc at an output signal of 1 GHz.
The R&S SMA100B can simultaneously provide a second, independently configurable, pure, and synchronized clock signal to a frequency of 6 GHz. As a result, users can characterize A/D converters with one analog signal generator.
The low wideband phase noise of the clock synthesizer output signal (100 MHz, -175 dBc/Hz, 30 MHz offset) makes it possible to measure the signal-to-noise ratio of modern A/D converters.
The R&S SMA100B also is suitable for a clock source when characterizing D/A converters. The generator?s low phase noise produces minimal signal jitter that does not influence the measurement results for the D/A converters.
