Reported early in this thread but with barely a mention since is the
Reference Position feature in Utility>System Settings.
Collecting our demo from a customer today they asked if the peak of a waveform could be magnified and displayed on the display just as some Tek they had did.
Not being near his lab I said I would send screenshots and a description of how
Reference Pos works, now also shared here for those that haven't used or explored it yet.
I've used a very simple example anyone can try with just the probe compensation signal, 3V @ 1KHz.
Yes, I'm in 10 Bit mode so to reduce waveform noise some at the 10mV/div (really 1mV) setting.
The Vertical Ref default setting is
Position that we all know we can increase input sensitivity until the waveform exceeds the display vertical real estate but we are constrained be the Offset limits on P10 of the Datasheet.
However when we select Vertical Position =
Offset we can zoom in vertically to examine the peak of the waveform as I show in the 2nd screenshot and with the graticule values displayed (Display settings) it's easy to see the real level of vertical zoom.
Horizontal ReferenceWhile here we should mention this too as it is very convenient when we need to have the H Pos away from the normal 0s position in the middle of the display. In the screenshots below I don't have it set to
Position but instead in the normal
Delay setting where as many will know that if the timebase is changed the 0s position moves with the timebase setting.
If we change the H Pos Reference Pos to
Position, changes to the timebase have zero impact on the H Pos setting and it will remain wherever you set it.
