41 | * BEWARE! "T1-T2" looks like a range, and is probably not a good | |
42 | * channel name. Using it in sigrok-cli -C specs is troublesome. Use | |
43 | * "delta" instead? -- But OTOH channels are not selected by the | |
44 | * software. Instead received packets just reflect the one channel | |
45 | * that manually was selected by the user via the device's buttons. | |
46 | * So the name is not a blocker, and it matches the labels on the | |
47 | * device and in the manual. So we can get away with it. | |
