Hello,

I am trying to transfer the waveformdata to the PC by VEE using all 8M memory.

With Channel1 and 3 on screen it is working and I get 8M points for each channel.

If I try it with only one Digital Channel (D0) on screen I only get 4M points. My commands:

":STOP"
":WAVeform:POINts:MODE RAW"
":WAVEFORM:FORMAT BYTE"
":WAVeform:POINts 8E6"
":WAVEFORM:SOURCE POD1"
":SINGLE"

":ACQuire:POINts?" says 5M points
":WAVeform:POINts?" says 4M points

What do I have to do to get 8M points?

Thanks
Christoph

I don't know your scope model but assuming you only have 1 pod enabled
you are getting the maximum number of digital points if your sweep
is in the range of 1ms/div to 20ms/div.

Thanks for your reply.

I scaled the scope to 1ms/div. No matter what I do, I only get 4M points for the waveform when I am using only use one Pod.
I don't know why, but today i get at least 8M points with the acquire:points command.

I attached two screenshots showing the problem.

You may have an idea how to get all 8M points?

I attached two screenshots and a Version of my VEE-File that is demonstrating the problem

One more question. Is there a document with an overwiev of maximal points for each range of timescaling? For sample rate i found the document 6000-series_sample_rates.pdf.

Thanks
Christoph

I was able to get 8M points from the digital channels and I admit the
solution is not obvious. Try the following(200 us/div is a limit)

1. Set only POD1 on, no analog channels active
2. Set the sweep to 200us/div
3. Execute a SINGLE acquisition
4. Read the number of waveform points available. It should be 4M
4. Set the sweep to 500us/div
5. Read the number of waveform points available. It should be 8M

Well, I tried this, but fo me it is still not working.

You tried it with a MSO6054A 8MH extension?

Thanks

I am attaching my VEE program to show it can be done. Are all of
your analog channels and D8-15 off?

Strange, even if i use exactly your order of commands, it is not working.
Did you made some manual settings which are not defauls after *RST?

Which version of firmware is installed on your Scope? I've got 04.02.0078

I manually turn off D8-D15.
I am running a proto version but 5.10 is close enough.

I hope, all of you had a happy easter!

Well, I updated my firmware to 5.0 and even with this it is not working.

Any ideas how I can get the other 4 million points I paid for?

I verified the procedure I posted on several MSO6000s and they all
returned 8Mpts. What is the response of the scope to the *OPT? query?

With the release of 5.15 for the MSO6000 scopes you will be able to
transfer all 8Mpts of the digital channels using the method previously
specified. I just verified the behavior on the Beta bits.
