Tek TDS340A is a successor to TDS320 and TDS340 DSOs. 340A added a real time calendar clock and 3.5" floppy disc storage that its predecessors lacked. It is identical to TDS 360 & 380 except for having only 100MHz bandwidth. Build quality looks rather fluffy inside, but amazingly their quality enabled them to last 20 years. They are not very repairable except for replacing their Li battery backed NVRAM, which after 20 years needs to be replaced, lest amnesia set in. This is not an end-user's task, and procedure's cost rivals that of scope itself, but it needs to be done if scope is to have a chance to last still longer.
