The UHFQA-DIG Digitizer is an option for the UHFQA Quantum Analyzer that extends the capability of the standard oscilloscope with digitizer features.
With its 12-bit physical resolution and 1.8 GSa/s sampling rate, the UHFQA-DIG is comparable to commercial standalone dual-channel, high-resolution digitizers. It enables simultaneous visualization of time-domain (digitizer) and frequency-domain (lock-in) traces in the same window. As the response of the analog input is flat at 600 MHz, sampling inside the Nyquist zone can take place at even higher frequency. The sample transfer rate of 7 MSa/s to the host computer ensures smooth transfer of large numbers of shots or long-time continuous digitizing at a reduced sample rate. Further, the option is fully integrated into the LabOne user interface.
