Hi,

I would like the ability to connect more than one probe at a time to ColourSpace and take measurements with both the reference probe (spectroradiometer) and the target probe (colorimeter) simultaneously during the probe matching process.

This would be helpful because of the drift/stability issues inherent in OLED displays - when you have to measure with one probe, disconnect from it, reconnect to the second probe, and take measurements again, it's hard to be 100% sure that the output of the display hasn't changed even slightly due to thermal drift, etc.

If you could measure with both meters simultaneously, you know the spectrum that the meters are measuring is the same since the measurements are taken at the same time.

Thanks,
Erik

You can do that already - but you will need to enter the recorded values manually into the Probe Matching window.

You just need to use the Remote Control capabilities to manage two Profiling Windows simultaneously.
See the 'Remote Control' https://www.lightillusion.com/video_guides.html for info.

The goal:
Performing probe matching simultaneously with both active and reference probe:

The Probe Matching process in CS evaluate RGBW patches by averaging 3 measurements on each.
These 12 measurements are performed similarly to manual measurements (i.e. applying to them stabilisation parameters, probe delay, etc).
So, running a dedicated user patch-set with those 12 patches emulates the above process.
Doing that simultaneously with both probes, from a master and a servant Profiling Window, can achieve this.

For averaging these measurements, it is necessary to collect all 12 measured values
The difficulty with the usual CS measurement recording (i.e. profile saving into bcs), is that with any duplicated patches, only the last one is saved.
As alternative to profile saving, there are Measurement Log and Secondary Execution.
As Measurement Log does not work on the servant profile, the only feature remaining is Secondary Execution.

Solution:
1. Open two Profiling windows, one for the Reference probe and another on for the Active probe
2. Activate on both Secondary Execution, recording in two different measurement data files
3. Run from display characterisation the user generated 12 patch RGBW patch-set
4. Use the Secondary Execution recorded values for generating the required bpd via the provided Excel file
To support the above solution, I have attached a zip file containing:

· the user generated patch-set I to be used (10 bits)
· a secondary execution bat allowing to pass a file name as parameter for differentiating output file name
· an Excel file to assess the measurements and generating the relevant bpd.
(A read.me sheet is included with explanations about its use)

Notes:
· Patch-set and excel can be easily modify to increase the number of samples on which averaging RGBW measurements
· A procedural easiest procedure is expected whether this [url=Notes: · Patch-set and excel can be easily modify to increase the number of samples on which averaging RGBW measurements · A procedural easiest procedure is expected whether this WIBINI is implemented.
