@michal Thanks for writing in, and glad to hear you’ve been satisfied with using your MSO so far! Thanks for all the feedback as well!

> How to manually set single shot durations.

Single shot durations (Pre-Trigger and Post-Trigger) are currently set via adjusting the horizontal zoom level only. You bring up a great point with regards to recording a fixed single shot length while staying zoomed into your signal!

I’ll mention this feedback to the team here. It would be convenient to set Pre-Trigger length and Post-Trigger length via a fixed numerical value (not affected by zoom).

For setting the buffer lengh, this could also benefit via a fixed numerical value configurable under Single Shot Settings. As a workaround to setting the exact buffer length you’d like, you can specify the horizontal range via numerical input by clicking the bottom-right like in the image below (Setting a 1s range results in a Buffer Length of 1GS in the example image below).

Do you mean when the waveform is clipped like in the image below (red lines at the top and bottom)?

So long as your input signal is within the Max Input Voltage specifications in our [Logic MSO datasheet](https://downloads.saleae.com/specs/logic_mso_data_sheet.pdf) (see below), waveform clipping is safe and you may zoom in and out as you please.

(PS I’m looking into your other questions, but wanted to provide my replies above in the meantime)
