For the Schnupp asymmetry measurement, one of the patch panel connectors on ISC R1 (by the PSL) is now wired to another patch panel connector on ISC R3 (by HAM6). The wiring is as follows:

• Existing patch cable: ISC R1 #11-4 → ISC C4 #2-4
• New 1 m cable: ISC C4 #2-4 → ISC C4 #5-6
• Existing patch cable: ISC C4 #5-6 → ISC R3 #15-6.

Initially, all these ports were labeled as "spare" and most of them were terminated.

The connector on ISC R1 will be driven by an rf signal from an IOT2R PD. The connector on ISC R3 will go into a spectrum analyzer.
