# What is the bandwidth of QSwitch?

The bandwidth is significantly larger than the QDAC-II bandwidth. Measured from a BNC input through a 3m Fischer output cable, the bandwidth is larger 5 MHz. Please note that the overall bandwidth in an experimental setup will most likely be limited by the impedance match of the in-series connected devices.
