I got an oscilloscope with this function and of course the first result I get while searching a video on how to use it, is from you. Concise and pretty informative as usual. Even when my scope is a different brand and model I had no problem using this feature after watching your explanation. Thanks. Seriously, I've learned so much from your channel. Thanks a lot for sharing your videos with us all.
I like that 485! My very first scope was a 531 used by bell labs in 1961. $600 was a lot of money back then! The delayed feature of newer Tektronix scopes paved the way for Tek to be the engineers favorite!. HP was a tough rival as time progressed. 73's Gary Grove
I am going through all your videos. Just got 3 485b scopes in broken shape. Trying to get one good one out of them! Thank you for answering folks questions in such a exact manner.
Wow. That is really awesome. I've had my Tek475 for two years now, and I hadn't bothered to learn how to use B (DLY'D) triggering until now. Thanks for showing me how to use that. The 485 looks like it has a few more bells and whistles!
Ok! I will be sure to check those videos out. Also, I would like to say I really like the ways in which you use the XY mode on your oscilloscopes, particularly the Lissajous patterns video.
Very interesting Alan. My 475 is somewhat different in the controls of the delayed time base. I have a Mix display which may be in place of the Alt control on your 485. No trace separation control either. I am just learning about scopes in general and this has shed some light on the delayed TB function. Thanks, Dave
Yes, the early 400 series used Mix instead of Alt. In MIX mode, the delayed timebase works on the same trace - the sweep speed is adjusted mid-sweep, at a position determined by the Delay control (basically where the Intensified portion begins in my video).
I just got a 2465CTS, I was trying to analyze noise on a waveform, I'm familiar with the delayed sweep on a 475, but I could not figure out how get the 2465 to do it. I scanned an online used manual index and didn't see it. Your tutorial came to the rescue. Thanks.
@w2aew thanks for the response! That makes sense. Your videos are very clear and concise, I'd love to see more practical applications esp. with the analog scope (I have a 2465A and an old HP54112d). From your response, I take it - you worked at Tektronix before? If so, in what capacity? I admire people like you who share valuable knowledge.
It's because the delays of the two signals inside of the signal generator aren't properly matched. The gate pulse is delayed too much with respect to the sinewave source.
@w2aew Awesome! Tek went thru some tough times years ago but it looks like they're back with nice products. Between HP and Tek, they've always set the standard for everyone else. I noticed that using delta T on my 2465A does not allow me to swipe the other edge of the gated RF WF, it does allow me to use the delta knob for the gate. Is that how it's supposed to be? I'd like to see more real-world basic apps for scopes and func gens for HAM circuits. Thx!
Thank you for your very educational videos. I have a tek cfg280 func gen. I preset the 280 to generate sine at 400khz and feed a gated 3khz square wave (from another func gen) to the 280 to basically get a similar signal that you have. However, I notice that the 280's counter readout shows approx. 200khz - can you explain why this is so? thx very much.
@w2aew I've watched you Charc. RF video but not able to do the same on delta T in my 2465A. ch1=gated RF, ch2=square wave. What happens is (ie.) before delta T is turned on, I have my delay hi-lited on the falling edge of the gated RF WF, when delta T is turned on, I expect to see that *other* hi-lite on the rising edge of the same WF but instead it appears on the gate source WF which is on ch2. So, I have a delay hi-lited on each WF (ch1 and ch2). I'm not sure if it's expctd for 2465A
@w2aew Hi Mr. Wolke, I posted a video response. In it, I show how it behaves on the 2465A and what I did to independently mark the rise/fall edges of the WF simultaneously for both CH1 and 2. Thanks for your guidance.
Yes I do - many of them! Here is one that is a recording of a presentation I gave at a local radio club: ua-cam.com/video/KYEMPm0c9kY/v-deo.html And here is a playlist with many beginner/tutorial videos on oscilloscopes: ua-cam.com/play/PL746BF38BC2E068E0.html
+w2aew I guessed that from your "delayed timebase frequency measurement video" on the 465B. I don't really like the Mix, they were right to change that :-) Thanks.
I would like to wish this video a happy 11th birthday!

fantastic video without overcomplicating a simple yet valuable oscilloscope function
Wow. That is really awesome. I've had my Tek475 for two years now, and I hadn't bothered to learn how to use B (DLY'D) triggering until now.
Thanks for showing me how to use that.
The 485 looks like it has a few more bells and whistles!
I'm glad you liked it. There are several more tips and tricks on the 465/475 series that you'll find in other videos on my channel. Enjoy!
Ok! I will be sure to check those videos out.
Also, I would like to say I really like the ways in which you use the XY mode on your oscilloscopes, particularly the Lissajous patterns video.
Wow that was so much easier than the reading the manual. Thanks.
Glad to see that this video that I made 7 years ago using my phone as a video recorder is still helping people!
Cool instructional video! I haven't used a scope in a few years and intend to start up again soon. This is great help!

465 here ... "Thank You Nurse! "
oh my gosh. I finally get it. thank you so much!
@w2aew thanks for the response! That makes sense. Your videos are very clear and concise, I'd love to see more practical applications esp. with the analog scope (I have a 2465A and an old HP54112d). From your response, I take it - you worked at Tektronix before? If so, in what capacity? I admire people like you who share valuable knowledge.
I have an old Hitachi V65F. If it can do this, I'll be shocked. It has similar controls that I apparently have had no clue on how to use for 30 years.
@w2aew I have the 465M. I could really use the trace separation, the mixed button is pretty much useless.
Hello Allen - I saw on 2:50 that the sine wave is appearing before the gate pulse that supposes to start that sine - how is that possible?
It's because the delays of the two signals inside of the signal generator aren't properly matched. The gate pulse is delayed too much with respect to the sinewave source.

Ole Tekz R00l!
Very interesting but recording volume too low
Sorry - it was one of the first videos I ever did, about 7 years ago, using a cell phone to record it. Glad it's still interesting though.
have you any vlogs for beginners
Yes I do - many of them!
Here is one that is a recording of a presentation I gave at a local radio club:
ua-cam.com/video/KYEMPm0c9kY/v-deo.html
And here is a playlist with many beginner/tutorial videos on oscilloscopes:

Is that "ALT" function specific to the 485? It's pretty cool to be able to see both timebases at the same time.
+fabts4 No, many of the better analog scopes with dual timebases give you this capability.
+w2aew So, is there something I missed on my 465 or is it not one of the better scopes?
+fabts4 The 465 has a Mixed mode only, unfortunately. The 465B has ALT.
+w2aew I guessed that from your "delayed timebase frequency measurement video" on the 465B. I don't really like the Mix, they were right to change that :-)
Thanks.
I wish my tek 465 had that mixed feature
nice!!
Zoom.
Exactly - it's how we did "zoom" before digital scopes.
You are the best.
