Q Switch
- Fischer Lines 24
- BNC Outputs 8
- Bandwidth >5 MHz
- Isolation Soft-grounded
- Control USB, LAN
- Chaining QDAC-II, cables
Q Switch is Quantum Machines’ software-controlled breakout box, connecting any of 24 Fischer lines to their fixed output or a shared BNC connector for monitoring and control.
It replaces manual cable swapping between experiment setups with a single programmable interface, so a full measurement sequence can be pre-programmed and run from a script rather than rewired by hand between runs. Built-in soft-grounding through 1 MΩ resistors protects signal lines during power disruptions, and the box connects to QDAC-II and the fridge wiring through two low-noise Fischer cables for a combined routing and voltage-source stack.
Overview
Q Switch is Quantum Machines’ software-controlled signal routing box, connecting any of 24 Fischer lines to their fixed output or to a shared BNC connector for monitoring. It replaces manual cable swapping between setups with a single programmable interface, so experiment sequences run without a hand on the bench.
Specifications
- 24 Fischer inputs, 24 fixed Fischer outputs, 8 configurable BNC outputs
- Bandwidth: greater than 5 MHz, measured BNC input to Fischer output
- Signal integrity: ultra-low noise, minimal crosstalk, twisted-pair wiring
- Soft-grounding through 1 MΩ resistors, with automatic grounding on power loss
- Control: USB and LAN interfaces, SCPI commands via Python
- Connects to QDAC-II and dilution refrigerator wiring via two 24-channel Fischer cables
Additional Information
- Not an all-to-all switch matrix; input lines route to their own output only
- Integrates measurement sequences directly into experiment scripts
- Enables off-hour, unattended experiments and shared standardized scripts across a lab
- Fischer lines twisted in pairs (1-2, 3-4, and so on) for noise immunity
- Made by Quantum Machines, available in India exclusively through Globetek
