Hello there so this is just a short video on how to keep your reference
waveforms on the screen whilst you're capturing the live data. There are a number of
ways to do this. But one that I really like the look of is is from a known
user online and he's got two viewports up. One with the reference waveform and
your known good capture if you like and then the live data underneath. So I wanted
just to demonstrate how to do that and we're going to do it in both
Picoscope 6 and Picoscope 7 to show you the differences and how to get
the two screens to work. So we'll start off in 6. So what we're going to do is
we're going to load in a known good reference wave form and this could be
one from the waveform library browser or one that you've already got saved. So
we're gonna go to open and have a number to choose from so I'm going to go cam,
crank and we'll have there we go so we have both the camshafts and an ignition
current sink as well. So we're going to put that on the screen. There's obviously
quite a long capture and you could opt for one that shorter but now if we
were to keep everything the same as what it is so if we were to set up our actual
live data capture in exactly the same way then we can leave all these settings
on the screen so everything's set up for you. So obviously bear in mind
anything with current clamps make sure that you've got the right current clamp
on the screen and this is obviously a 60 amp and 20 amp mode and then obviously
the ranging and the scale and we'll all be correct. So just bear that little that
thing in mind. Now very quickly in Picoscope 6 what
we can do is we can right click and then we can just go reference waveforms. Now
I'm only really interested in the cam and crank signal so I'm going to do a
reference of A, B, C and that will do us. So now obviously it's looking extremely
messy on the screen right now so what we're going to do now is obviously split
all this up into two different viewpoints. So if you go up to views and
then add view and scope it will load in underneath another
viewport. Now if we look at the two this one looks like the original capture that
we had at the beginning now if we right-click again we can see that the
active channels in view are A, B, C and D and a referent ones are actually hidden.
So we're going to keep that as it is but in the top viewport again just navigate
up to the top and right click on the grid here and then we can see that we've
got all of them actually active. Now we don't really want the live ones anymore
so we're going to get rid of all of those including channel D we're not
really interested in channel D for a Camcrank sync it's just purely as a
trigger to keep things on the screen. Now again everything's still looking a
little bit bunched up so we could just separate them by moving the axes around
and doing as so or the other way of doing it is actually can right-click and there
is an auto arrange axis. Now be careful here because it can actually change the
scaling so things will look different I tend to just like to move them around
and then adjust the scaling if I need to to get everything to fit but as a quick
solution obviously the auto arrange is there just to help out with that point. So
again now this will obviously stay here now so we can make all our own
amendments we can zoom in we can treat this as a completely different scope
capture. We can add rotation and nothing's affected in the one below. So
I'm not actually at a car at the moment to do a live demonstration but if we
were to press star as you can see this one's stayed exactly the same and now at
the bottom we've got everything running and I think if we move the channels
around we can actually have all of them all of them identified separately again
also a range or just to move the axes by shifting up and down. So I think we can
see this is actually quite useful again you might not have even had a trigger at
that point so then it's just a case of locating two two rotations of crankshaft
to give you some reference points on here so we
can see obviously we've got to two towers there if you like from there
which one was that that's the intake camshaft sensor and so we can sort of
use them as reference points to actually then match up with our live data and
actually compare a camcrank sync. Okay so that's how it is in 6! Now if we do
the same type of measurement in 7 so if we go to 7 now this hasn't got a
scope connected so we are just in demo mode on here. But again we're going to
use the same principle we're going to open up an existing an existing capture
and I'm trying to remember which one it was now so lets just go back quickly
so back to Picoscope 7 on the screen as it was before so you have to do something slightly different
in here because there's no right-click functionality at the moment. So if we go
to views and then we want to click on references so sorry that should be
references first we want to click on the references button when we get this pop
out. Same thing again was how it was in 6. So what we gonna do is just a
click I'm just gonna add and add them all in so actually I've added channel D
and I didn't really want to add in channel D so if you do want any
the manage is here so we can take to channel D and we can remove.
We can see that they've actually loaded in the colors as per 6 does so it will
put the default colors . If you want to change the names or anything like that
you can do all of that in this section here. Again for exporting you can
actually save and it will save your reference waveforms to a library where
you can also call them upon and whenever you need them again. So click anywhere
outside the grid and then it collapses everything. Again everything's looking a
little bit messy so if we go to views now we can click scope as before now
let's just put the live on underneath and in the top viewport we can see
everything is still here. So again if we go back to
views and we've got the show hired channels here so we can actually
deselect the ones that we don't want and we would just be left with our
references. So again dragging along the side will actually move your axes around.
If you want to do any scaling in 7 and we could actually just hover over
the axis if you're using a mouse and if using a tablet there is the option to
pinch on this axis as well and that will actually adjust your scaling. So you can
see here I'm just rotating the mouse wheel at the moment and you can see how the
scaling is changing and you also can do this from within the channel options. So
you have to go to display and then you have the options here to actually change
what you have. Now obviously this is a reference waveform in the top so bear
that in mind as well so again we've got the vertical scale here so this is how
we change it in 7 for your references. Again at the bottom I'm just
going to literally use my mouse wheel just to change the scaling, just a touch
just to bring everything to view a little bit better. You do also have the
option now to actually pull that out completely
and if you wanted to maximize the whole screen that's another option and if you
want to keep your reference on then you actually also have the option to move it
to the side should you wish. And so it's just a bit more flexibility in 7
with how you want to set things up to view it. You can also actually drag this
toolbar to change the height of it so you can actually have a bigger increased
area of the actual data or actually vice versa you might want the actual
known-good slightly bigger so you can see it. So
there's all these options that's still present but I hope that helps.
Keep the feedback coming in for 7 because we do constantly want to keep making it
better and improve it all the time. And keep an eye out for the software updates
because there will be new features coming as and when. So
do keep letting us know. I hope this helps and take care of yourselves out there everybody.
you
