Re: First dual delay sweep?


Hey Chris,

that's interesting. The TekWiki page <> for
7B85 has a link to this 1976 TekScope issue
<>, which looks
to call it out as the first timebase that will directly read delta
time between two delays. There's mention of DM40 and DM43, which allow
reading delay time and zeroing, so indirectly reading delta time.

Is the 2465 the first Tek scope to provide a (calibrated) dual delay?
Surely there are ways to do the same with the 7K mainframes and suitable
horizontal plugins?
The 7B85 delaying timebase can certainly do this in a 4-bay 7K
mainframe, and according to Tekwiki they date from 1976 which somewhat
predates the 24xx series.
