Oscope Normal mode used as a storage scope?

[stanleystan]

How can you use an Oscopes normal trigger mode like an storage scope?

You can use the external trigger on normal trigger mode? the O scope will capture and save one time period of the waveform?

In normal mode where is the external trigger event start at?

On Storage Scopes, there will be an indicators "T" to let you know where the External trigger event started. So you can measure with the cursors from the Letter T to the positive or negative edge you want to measure and get a time duration

What type of time duration measurement is this called when you're measuring from the External trigger event to the a negative transition or the next pulse leading edge or falling edge?

Can you do this using the Normal trigger mode?

On all decent scopes there is an inbuilt delay between the trigger circuitry and the display which is delayed by a long piece of coax, quite often wrapped around the tube. This is so the signal comes in starts the sweep and 50nS later the signal appears on the screen, so you can actually see the edge that caused the trigger to fire.
On storage scopes, the display is played out from a memory and the T marker is just a timing reference inserted later.
