VSG200 20 GHz Vector Signal Generator

The VSG200 is a 20 GHz vector signal generator with 40 MHz of real-time streaming bandwidth. It offers the performance and versatility of an enterprise-grade vector signal generator to a broad range of users. It is a high-performance test and measurement device capable of generating any signal type.


The VSG200 features a low phase noise, agile local oscillator with 200 µs switch time, enabling frequency hopping spread spectrum testing. A dual 14-bit DAC runs at 2x or 3x the I/Q symbol rate using digital oversampling to provide a flat, clean baseband; and a digitally adjustable internal VCTCXO ensures frequency errors are kept to a minimum over temperature, or an external 10 MHz input may be used for zero ppm frequency error. A trigger output is also available to synchronize your VSG200 with other test equipment.

Available modulation types

LTE, 802.11a/n/ac/ax, Bluetooth LE, Custom OFDM, 16/64/256/1024-QAM, 2/4/8/16-PSK, 2/4/8/16-FSK, ASK, GMSK, AWGN channels, Ramp/Chirp, Stepped sweep, Multi-tone, Pulse, FM, AM, CW, Arbitrary/Custom.

Digital modulation impairments

Custom channel response, AWGN, Sample rate error, frequency and level offset, I/Q offset, spectrum inversion.

Other features

Use the API to continuously stream custom I/Q data to the VSG200 at arbitrary sample rates up to 51.2 MSPS. Use the external trigger output to synchronize multiple instruments for complex measurement setups. Take advantage of the 10MHz timebase input to ensure frequency coordination between all lab equipment.
