USB 3.0 Connection Exerciser
The MCCIŽ USB 3.0 Connection Exerciser Model 2101 is a tool that automatically connects and disconnects a USB 2.0 or 3.0 host and device under software control, without requiring that an operator physically manipulate a cable. The microcontroller and the high frequency relays within the Model 2101 can either be operated with a pre-programmed connection pattern or can be controlled real-time through an auxiliary USB port using a Control PC. The Model 2101 Connection Exerciser is a useful tool for finding software defects in host drivers and embedded Host Controller Drivers (HCD). Use it to find and analyze USB 3.0 connection problems in a well controlled and repeatable manner.
- An impedance controlled, low loss USB data path. The Exerciser is transparent when in the connected state
- Data relays are rated to 7 Ghz
- VBUS and Data signals are connected and disconnected in the same sequence as if done manually
- The ground connection is never broken
- Connection time can be controlled down to 10 ms
- Device Under Test (DUT) VBUS is optionally configurable for flow-thru or buffered operation
- Control PC needs no drivers. Native HID drivers are all that is required
- The 2101 can be powered from any of these three sources:
- External 5 V power supply
- Control PC VBUS connection
- Host Under Test (HUT) VBUS power supply (optional)
- The 2101 can also be used for testing low speed, full speed, and hi-speed devices and hosts
