I have recently received an old 70's era Tektronix 465b dual trace oscilloscope. Unfortunately I have close to no clue how to use it.

I understand the concept of triggering but this scope has two triggers, named trigger A and trigger B(DLY). Is trigger A for channel 1 and trigger B(DLY) for channel 2?

Some insight would be greatly appreciated as the manual is nearly useless in describing this.

    \$\begingroup\$ This is a very fine scope. Learn to use it, take care of it and find out how to repair it if it breaks. It will serve you well in electronics. \$\endgroup\$ – John Honniball Nov 14 '14 at 15:30

    \$\begingroup\$ As @JohnHonniball says, that's a good solid scope, and it can be more trustworthy than a digital oscilloscope (no aliasing, for example). Also, unlike some slightly newer scopes from Tek, it's pretty repairable if you have the service manual. \$\endgroup\$ – Spehro Pefhany Nov 14 '14 at 16:32

The 465B has two time base, A and B. The B time base is called delayed time base and can be used to zoom on a portion of a signal to see it in greater details. You can also trigger on this zoomed signal by using the trigger B (and the "DLY" is for "delayed" or "delay").

You can watch some videos from w2aew on youtube here. He has differents tutorials on Tektronix oscilloscopes.

In Tek's Triggering Fundamentals, page. 12, it gives explanation about "Delaying triggering" and "AB.Sequence.Triggering". And i think you may need this old guy's service manual: http://bama.edebris.com/manuals/tek/465b.
