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.
