Can you tell me, on the measurement menu, for rise time, fall time and pulse width, can you set the reference point? By default the mid reference points are usually 50%, but in my uses, for Fall Time, I set it at 10% and 90% and the mid reference points both at 10% (or 90% depending on the perspective). This is how you measure the values of an ultrasonic pulser. I can see on a flyer that you can measure pulse widths, fall time and rise times, but I don't know if you can set the reference measurement points for those readings.
The default and only reference points that are mentioned in the manual are 10 and 90% but they apply in the reverse for fall times as stated in the manual on P127.
In a screenshot below I have just one auto measure for fall time, the waveform inverted and the measurement gate activated FYI. The waveform is just the probe Cal

I think the tricky measurement is the pulse width at reference points other that 50%, as in the example I attached.

Here's a pretty low level signal contrived from an AWG to in some way represent daveyk's example a few posts back.
It has a small negative DC offset so AC coupling was needed to display it correctly. High and low peaks are both negative values.
The falling edge measurements are more accurate at faster timebases or with multiple edges shown on the display.
Stats, Fall time and negative

The MIN, btw, which does not matter for the example is often -350 to -400volts. Being very narrow pulses and generated from the discharge of typically a 1000pf 1kv orange drop or mica cap, there's no "oomf" behind it.

Typical widths might be 110ns. What I don't see is if can display the width at 10% down from the top. In your example, we can not see the right side of the "pulse" going back up to the baseline.

I agree but looking through the op manual I didn't see a mid reference level setting for pulse with. They talk about pulse width being measured at 50%, but don't show a way to change that.
Even so, $380, wow.

You can set the angle of a triangle waveform, to turn it into a sawtooth, I did that yesterday in the 1032x

Not easy when using automated data collection software. You need to be able to tell it to send you the pulse width with the mid references set to 10%.
