The VSG60A 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 VSG60A 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 VSG60A 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.
