SGS100A-B106V ATE vector signal generator, 80MHz – 6GHz, with integrated I/Q modulator

The SGS100A is an RF source designed to meet the requirements of automated test systems, the B106V model is a 6GHz vector signal generator with an integrated I/Q modulator.
Features:

• Enables high throughput due to very short frequency and level setting times of typ. 280 µs via PCIe/Ethernet interface
• Closed ALC loop for CW and I/Q modes for highest level repeatability
• Cost-efficient and compact frequency extension to 40GHz with the SGU100A upconverter

An important characteristic for the signal quality of RF signal generators is SSB phase noise. This value is important for CW applications, for example when searching for a pure local oscillator, and also for digital modulations. SSB phase noise directly influences the error vector magnitude (EVM) of digital signals, a parameter that is significant for advanced OFDM-based systems such as LTE. For interference and intermodulation tests, very low non-harmonics are an indispensable characteristic for the test source. The SGS100A is ahead of the game here as well, offering excellent values otherwise seen only with high-end instruments. At an output frequency lower than 1,5 GHz, it achieves < –76 dBc (offset > 10 kHz).
Specifications:

• CW frequency range: 1MHz to 6GHz
• IQ frequency range: 80MHz to 6GHz
• Specified level range: –120 dBm to +15 dBm peak envelope power (PEP) with option B26
• SSB phase noise: –133 dBc (meas., 20 kHz carrier offset, f = 1 GHz, 1 Hz measurement bandwidth)
