Does the Model 3501 Type C SuperMUTT replace the Model 3101 or 3102 Connection Exercisers?
No. The functions are much different.
The 3501 is an active device emulator.
- The 3501 is primarily a device emulator, not a multiplexor; the extra Type C connector on the front panel is for PD source and sink testing, not for USB testing.
- The 3501 can emulate a PD source or sink by supplying up to 100W (with optional high-power supply) or 60W (with the standard power supply)
- The 3501 includes USB SuperSpeed gen1 device emulation.
The 3101/3102 are device multiplexers -- they switch external devices and connect them to the unit under test. They have no ability to generate USB or PD traffic.
Some Microsoft tests for Windows originally used the 3101/3102 for testing host PD functionality. Once the 3501 was ready, those tests were converted to use the 3501. However some USB tests (such as unplug/replug tests) may continue to use the 3101. Contact Microsoft for more information on Windows tests requirements.
