3. Receiver Tests
3.1. Rx: Standard-A & Micro-B Gen 2
See TD.1.8, and TD.1.10 in the CTS.
Standard-A and Micro-B Gen 1 Rx Tests require USB 3.0 or 3.1 fixtures.
As of January 2017, there is no official short channel fixture for Standard-A and Micro-B Rx testing.
Use a third party Gen1 short channel fixture.

4. CC Jumpers
Only use one jumper.
Place a jumper on CC1 if SMAs are connected to Tx1/Rx1.
Place a jumper on CC2 if SMAs are connected to Tx2/Rx2.
When using the Full Breakout, connect CC to Vbus for devices, or connect CC to GND for hosts.

5. SigTest Templates
Please refer to the USB-IF website for the SigTest installers. There is one version for Gen1 and a different
version for Gen2 testing. The SSC Profile test (both Gen1 & Gen2) must be performed with the Gen2
version.
