High-speed Signal Processing with Low Latency Feedback System
for Quantum Bit Evaluation

Evaluation systems for quantum technology require signal generation for Qubit control, readout signal generation, post-signal processing of signals read, etc. Control based on the results of signal processing using a digitizer and feedback within coherence time and readout signal variability are becoming essential.
The M3000 series processes signals at high speed. Using the optional programmable FPGA DSP capabilities with the Hard Virtual Instrumentation (HVI) provide real-time technology that reduces the decision execution time from the digitizer to AWG to x100 ns.

· Provides time control with 1ns resolution using M3202A 1 GSa/s Arbitrary Waveform Generator
· Determines the next action based on the result of signal processing at the digitizer and executes sequence control to AWG with minimum delay time within the coherence time
· Executes accurate, multimodule synchronization and timing control with built-in sequencer technology (HVI technology)
· When combined with the M9383A PXIe microwave vector signal generator, the entire system can be built in PXIe. A PXI Network Analyzer can also be added for resonant frequency search
