Setting vertical scale in FM vs Time in zero Span – SOLVED

[Gary]

UPDATE: Forget it! Figured it out. You have to first right-click on the display, select “Enable Zoom”, then click and drag on the display itself to set both the time and amplitude zoom feature.
——————————
In previous versions of Spike, it was possible to set the vertical scale of the FM vs Time display while in zero span. I can’t figure out how (or even if) to do it in the current version (3.3.0). I’ve noticed that you can move the center line up and down by click-&-drag, but that doesn’t change the scale.
I know that you can effectively change the scale by setting the sample rate, but I was wondering if it was possible to set the scale straight on the display.
Thanks!

Hi Gary,

You can also scroll the mouse wheel in the same location where you click/drag the y-axis and this will also change the scale.

Thanks, Andrew. I was using a laptop with a touchpad. I’ll have to add a mouse for this reason.

Hi Gary,

Two finger swipe up/down usually emulates mouse wheel up/down on modern laptops.

Regards,
Andrew
