Question 1: I understand that the standard warranty on these devices is 12 months. How is this time interval measured? In reviewing the invoices and packing lists from parts purchased thru distributors I find no record of unit serial numbers. Indeed, this is not a surprise as the serial number and manufacturing date code only appear electronically from reading out the unit. This leads, however, to a scenario where there can be an appreciable time interval between manufacture and then a delay thru distribution before delivery. From reading out received units I note a period of 3-4 months between manufacturing date code and the delivery date. Does the warranty then "tick off'" while the unit is on a distributors shelf or is there a mechanism to set the warranty start time at delivery from distribution?
Question 2: Does Analog offer an extended warranty (presumably for some fee) for this part?
