Thank you once again to the software teams for their continued dedication to the development of PicoScope 7 Automotive Early Access 7.0.121.14753 (inc. Pico Diagnostics 1.16.88.0) which can be downloaded here https://www.picoauto.com/downloads

New features

Phase measurement

PicoScope 7 now includes Phase measurements to display the phase difference between two selected channels
• Click on the “Measurements” button in the left-hand tool panel to reveal the measurement options
• Note, we now have a “beta” Multi-Channel measurement option called “Phase”
Image 1
Image 1
• Click on the “Phase” measurement to display the phase difference between channels A and B. These are the default channels for phase measurements, with Channel A being the “Source” channel and Channel B being the “Source 2” channel by which to measure & display the phase difference
Image 2
Image 2
• Clicking on the settings “cog” within the measurement lozenge will reveal several options to modify your phase measurement:
• Below we can amend the “Source Channels”, choose the section of the graph to measure, select an “Output Range” (default 360°), decide on how to determine the measurement “Threshold” and finally, the level of “Hysteresis”
Image 3
Image 3
• Below we have added multiple “Large” phase measurements between all phases using a combination of “Between time rulers” and “Whole trace”
Image 4
Image 4
• In the following image, we have created a second scope view and zoomed into identical areas of the graph; Scope view 1 displays the phase measurements “Between the time rulers” for all channels. Scope view 2 uses the phase and time rulers to qualify the displayed measurement value for Channels A & B (i.e., displayed measurement for Channel A & B = 122.1°, phase and time ruler measurement for Channels A & B = 122°)

Hi Steve,
This is exciting. I couldn't wait to download the latest early release to check it out. I'm always looking for ways to apply all the many features in PS7 to automotive diagnosis. I'm wondering if the Multi-Channel Phase measurement can be used to map out the phase timing that takes place between a crank signal and the camshaft changes in Variable Valve Timing (VVT) vehicles. Correlating the timing based on VVT solenoid duty cycle could help a lot of technicians during VVT diagnosis. If so, could you provide guidance and instructions?

Hi Steve,
I hated to give up Pico 6 and now I absolutely love PS7 and I'm not looking back. For those of you who don't want to move just know that Pico is not putting anymore development into PS6. The advancements, features and easy access to features is awesome and with a little effort playing with PS7 in demo mode in your off time you will come to love PS7 too. I'm an instructor who teaches technicians scopes and every PS6 user whom I teach PS7 leaves class saying they are going home and installing PS7 as soon as they get back to the shop. For those of you who can't find the properties window because you are always readjusting your sample rate to make sure you don't over or under sample. That is gone because there is no need for it anymore. PS7's sample rate mode solves that. Set the sampling to "Sample Rate". Now return back to the scope and change the timebase and watch the sample interval at the bottom of the menu. It doesn't change at all, the sampling is consistent over a wide range of timebases. It will change a little at the very high and very low timebase settings. This is fantastic and one major reason to switch. You can now prevent under or over sampling anytime you change your timebase during diagnosis. I have some PS7 training videos that are short and helpful on my YouTube channel "DrivelineMaster" (https://www.youtube.com/drivelinemaster) and I plan more in the future. By the way, the new zoom and measurements are also awesome. Thank you Pico from an instructor who was also hesitant to give up PS6.

Hello and thank you for the post and what a question too.

Thank you also for the training you provide to the delegates under your wing. Rest assured you are changing lives and make this challenging profession a little easier by instilling knowledge (nothing is easy)

Moving onto your request, we wish to graph the change of phase between cam and crank in relation to a change in VVT duty control

Starting with our next proposed release of PicoScope 7 Early access version 7.0.124 we will have phase math’s and delay measurements which I will add here as soon as it is released

Below is a preview
Image 1
Image 1

The above could go someway to graphing the change in correlation between Cam and Crank and I will get to work on this ASAP

In the meantime, we have looked at such options here looking at inter channel timing measurements with Deep Measure topic21776.html

Deep Measure for PicoScope 7 can be found here viewtopic.php?p=103559#p103559

Here topic21754-10.html we capture the phase shift using cam and crank correlation measurement techniques and reference waveforms

Scroll down to the animation and video within the above forum post link (I think this would good for the delegates to practice)

The next forum post looks at numerous options when it comes to triggering across engine ranges; not quite what we are trying to achieve but worth noting if we do not have scan tool control over VVT duty and wish to free the engine instead viewtopic.php?p=103937#p103937

Ironically at the end of the above forum post we allude to a “rotation domain” which would be very helpful indeed (Noted by Pico and the software team, said too much already)

We have experimented with a half way house towards a rotation domain using the frequency of the engine as our X axis viewtopic.php?p=100319#p100319 This would most certainly be worth revisiting to see how we can demonstrate correlation shift live

Persistence mode would be another worthy journey too viewtopic.php?p=104061#p104061

I will get to work on a number of these techniques and feedback ASAP (Likely to me be mid next week)

I hope these help in the interim and I hope it does not feel like I have answered your question with a question

We live and learn together

Take care…..Steve

• Click on the “Delay” measurement to display the configuration panel where you can specify the “Source” and “Source 2” which are the channels you wish to measure the delay in terms of TIME (seconds)
• In addition to the above, choose the area of the graph you wish to measure “Delay”, (i.e., between the Time rulers) along with the desired scope view, threshold and hysteresis levels
Image 2
Image 2
• Note below we can confirm the “Delay” in terms of Time between “Source” (Channel A) and “Source 2” (Channel B) between the time rulers in scope view 1 is 2.720 ms
• Note also how scope view 2 measures this time delay manually between channels A & B at their respective 0 V crossing point
Image 3
Image 3
Feedback on the design and function of the “Delay” measurement feature would be most welcome

• Choose a name, colour, units, and Min/Max range for your phase math channel and close the wizard by clicking on “Finish”
Image 5
Image 5
• Below we plot the phase difference (shift) between channels A & B with the magenta math channel named “phase(A, B)”. Assuming our phase remains fixed between channels A & B (Approx 120 °) then our math channel should resemble a straight line at approx. 120°
Image 6
Image 6
• Below we repeat the above process but use “Delay” instead of “Phase” to graph any deviations in the time delay between channels A & B
Image 7
Image 7
• Note above the black math channel “Delay(A, B)” returns any deviations in time between channels A & B where once again (assuming our delay remains fixed) our math channel should resemble a straight line at approx. 0 seconds

Feedback on the design and function of the “Phase & Delay” math channel feature would be most welcome. Click on More > Send Feedback within the software

Rotation partition count increased

Rotation Partitions can now be increased to 32 from the previous maximum count of 12

• Click on the “Rulers” button in the left-hand tool panel to open the Rulers tool panel
• Select Phase rulers “On” and amend partition counter to a maximum of 32
• Below we divide 720° of crankshaft rotation by 32 partitions to derive 22.5° intervals
Image 8

Following on from the measurement limits feature above, all waveforms that pass or fail your set measurement limits can now be filtered within the Waveform navigator. This will make it easier to find and view all waveforms that pass or fail your set measurement limits.

• With your measurement limits set (as described above) and data captured, stop PicoScope and click on the Waveform navigator lozenge
• The Waveform navigator control panel will open to reveal the “Show thumbnails” field
• Using the drop-down arrow within the “Show thumbnails” field, select the desired option
7

• Below we have requested the Waveform navigator display only waveforms that failed the RMS measurement limits set on channel A
8

• Below; PicoScope 7 displays only 2 of the captured 25 waveforms as only buffer 22 & 23 meet the criteria of “Measurement limit failures on RMS (A)”

Show previous waveform

A new control has now been added to enable / disable showing the previous waveform while in progressive (streaming) capture mode.

• With PicoScope time base set to 200 ms/div or slower, click on the Time base and Sampling lozenge
• Select the Sampling tab and turn on the “Previous progressive waveform” option
10
10
• Run PicoScope and note how a vertical line passes across the graph view from left to right during capture
• With the “Previous progressive waveform” option set to on, the previous waveform buffer remains on screen whilst PicoScope 7 draws the new “current” waveform alongside.
11
11
• The above feature will enable filtered data (i.e., Low pass) to displayed simultaneously with live unfiltered data.
• This will allow the user to view signals continually on screen rather than waiting for the live waveform to be drawn before the software momentarily displays the filtered signal when the buffer is full. I.e., the user will now have a continual view of the filtered signal without having to stop the capture and scroll through the Waveform navigator.

The following video will help clarify the description and operation above

Measurement “Limits” linked to “Actions”

Following on from our measurement “Limits” feature described earlier in this post, it is now possible to link “Limits” pass/fail results to “Actions”

• With Limits configured on your chosen measurement click on “Actions” to reveal the Actions dialogue box
14
14
• Click on “Change event” button within the “Actions” dialogue box
• Below we have chosen “Measurement limits failure” as our “Event” upon which to return an “Action”
• Note below how Channel A Measurement (Frequency at peak) includes an upper limit of 200 Hz and a lower limit of 110 Hz

15
15

• With these limits in mind and our chosen “Event”, we need to choose an “Action” by selecting “Add”
• Below we have opted for “Play sound” when the Measurements limits fail

16
16
• Choose the desired sound, below we have opted for “Beep”
17
17
• To summarise our configuration above, for as long as our “Frequency at peak” remains between 110 and 200 Hz, the measurement lozenge figures will remain black in colour. Should our “Frequency at peak” fall outside these limits, the measurement lozenge figures will change to red and the user will be notified with a “beep”

The following video demonstrates the above measurement feature using our Belt tension Guided Test

Thank you once again to the software teams for their continued dedication to the development of PicoScope 7 Automotive Early Access 7.1.16.17168 (inc. Pico Diagnostics 1.16.110.0) which can be downloaded soon here https://www.picoauto.com/downloads

New Features
When enabled, your Measurement limits pass and failure counts are displayed on the measurement lozenge.

• As described above, Measurement limits can be applied to a desired measurement
• With the Measurement lozenge size set to “M” (Medium) further information and indication of Failures & Passes are displayed
• Below we have a maximum number of buffers stored (36) with 4 failures and a total number of 78 passes displayed in the measurement lozenge
• We can therefore conclude, given that all our 4 measurement failures are present within the Waveform Navigator (29-35) all 74 previous waveforms (78 passes – 4 failures) passed the measurement limits
