Just one of those things that you forget about unless you need it. I purchased a Tektronix 475 last year and the trigger has always been a bit "fiddly". I just took a look at the front panel and noticed that the hold-off wasn't in its "cal" position. When I was in USAF electronics we really needed that feature, NO storage scopes back then.
Excellent!, i knew what holdoff was, but i never really understand when to use it, i never thought that when you zoom in, your trigger will start working again for signals outside the screen, and cause that. thank you!
"...you don't ever use it and you wonder why is there" That's absolutely right. I learned something new today even though I have been using oscilloscope for 40 years. Thank you! Perfect little tidbit at a Friday night.
What I did not know is that zooming in/out may effect the trigger point. I wonder if that is true of all scopes/makes/models? I would have thought that the trigger point that was originally programmed would have remained the same, regardless of zooming... Maybe you have to initiate the hold function (of Run/Hold) to zoom in/out, without the trigger changing?
@@frankowalker4662 it's been a while since I've used an analog scope but if I remember correctly it was in one of those inner knobs somewhere in the trigger section, but I've never used a Phillips or fnirsi scope.
@@Gengh13 My Hitachi dual trace analog probebly does have it, it's just there are so many knobs and switches on it. Most with muli-function if you pull out the knob, or push it in and turn it, or turn it till it clicks then pull it out. LOL. The Fnirsi is a cheap Chinese dual trace with a terrible touch screen that gets laggy about 1GHz. But it's small, portable and rechargeable.

Thank you!
great video , i would like to see more videos on digital oscillosope features
Good information and the application of it. Thank you. More, please.
Thank youuuu.
Good to know....
facepalm, facepalm, facepalm (remembers all the times I struggled) FACEPALM *FACEPALM*
Very nice! Can't wait give it a try.
Wow thanks for that!!! pls do more videos like this on simple-but-rarely-fully-understood oscilloscope features and functions!

In analog world, monostable multivibrators take place.

Useful info. I don't think my scope has that function though.
Holdoff? As far as I know most scopes have it, even analog ones. That's a basic feature.
@@Gengh13 I can't find it on my Hitachi 1980's analog or my Fnirsi digital scopes. Unless it has another name. (which I doubt)

@@frankowalker4662might be called "trigger delay" or something to that effect.
