Agilent DSO6104l and memory use?
« on: September 04, 2018, 02:51:57 am »
Hello,

I don't understand the use of the memory in the Agilent DSO6104L (this is a rackversion of the DSO6104A)

In "DSO6104l_run.jpg" is an acquisition with high res mode in run modus.
There is 1Mpts used from the 8Mpts memory.

In "DSO6104l_single.jpg" the acquisition with high res mode is now in single mode. This is the only change.
Now is 4Mpts used.

I suppose that in high res mode a sample is 16 bit and in normal mode a sample is only 8 bit. And the 8Mpts in the datasheet should better called 8MB

But why is in single-mode 4 times so much samples as in run-mode?

Can anybody this please explain.

Best regards
egonotto

Read the manual. In run mode the oscilloscope cuts the memory in half to use double buffering (half the memory for acquisition, half the memory to process for display).
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Hello,

I would understand half the memory in run mode for double buffering and again half for high res-mode. That would give 2Mpts.

But it is only 1 Mpts. From where comes the third half?

Hello,

the save of 8000000 pts ASCII XY data file to USB-stick needs about 50 minutes.

The file is 178MB.

Download it as binary.

And then use "M1WV" (M1 Waveform Viewer) to save as CSV or XLS.

Another option maybe can be this tool VISA TM Data Capture: http://jahonen.kapsi.fi/Electronics/VISA_TM_DC/
I think it allows you to save as csv, I don't remember if it is faster through the LAN.

Also "Agilent IntuiLink" can open binary files, but it can't export to csv, so I add other tool in attachments "binToAscii", it convet from bin to csv.

If someone knows more tools, please share.
My English can be pretty bad, so suggestions are welcome. ;)
