DPO 4000 automation

[felpx]

Hi

I want to automate several actions with my DPO4000, to aquire waveform info from it, meassure it, analize it and finally save all of this in my PC.

It is possible?

How many time could it record?

Does it mather the record lenght?

Thank you

obviously with NI software

Are you talking about the DPO4000 series of scopes from Tek? If so, there are drivers available for some models on the Instrument Driver Network. Even if you don't use a driver, if you have the correct hardware to interface to an instrument (i.e. GPIB controller), you can automate just about anything you want.

Does record length matter for what? Obviously, the bigger the record lengths, the longer it will take to transfer and require more disk space for storage.

You are using what type of NI Software? LabVIEW, LabWindows, Measurement Studio?

Thanks for your answer.

Yes I am talking about Tektronix scope DPO4000

so, could I live the DPO working and programm a routine that adquire the data, meassure it and store it in memory?

My question was because I read with USB conection it can't be transfer more than 100k

I am using SignalExpress

Signal Express has it's own board that you should post specific questions to. I've never used it.

I'm not aware of any limitation that USB has regarding how much total data can be transferred over it. What reference do you have to 100K? I regularly transfer files much greater than that from the pc to a custom USB device.

There should be a special Tek DPO4000 step that installs with SignalExpress Tek Edition.  Otherwise, you can use an IVI driver with the IVI Scope SignalExpress Acquire step:

Using the special DPO4000 step is your best bet, with the other option as a backup.  Dennis is correct that more SignalExpress-savy users will be in the SignalExpress forum.
