Hi Michael,

1) No, the max record length is 62.5 Mpts, no matter how many channels you have enabled.
If you require a longer record length I would suggest the MSO5 with 500 Mpts or the MSO6 with 1 Gpts.
(All of these might require paid options to unlock the full record length)

2) The transfer speeds are dependent on many factors, including: connection type (USB or Ethernet), transfer format (ascii or raw ints), waveform type (some waveforms are 8 bits, other 16 bits), etc.
I would need to know the specifics of your setup and measurement to be able to give you a more detailed answer.

In terms of offline analysis, the easiest and most robust option is to use our TekScope software.
You can also use SCPI to transfer waveforms to your computer and then process them with your own software.

Hi Xiang,

The command you want to use to configure the source for a measurement is measurement:measX:source

Hi Michael,

I do not yet have any news on a software fix for this issue.
I am working with our teams on other possible solutions and I will contact you through email to discuss them.

Hi Carrie,

How high impedance are you talking? How does this evolve with frequency?

You can have a circuit that is very high impedance at DC but at high frequencies presents low impedance, which would explain the problem you're seeing.

If your circuit has low impedance then what you can try to do is characterize it and then adjust the AFG amplitude accordingly.

Hi Carrie,

This sounds very similar to the thread you made a month ago.

As discussed there, the problem is likely your circuit which is loading down your signal. Do you know the impedance of your circuit?

Hi Noa,

The data is given as time (in seconds) in the left column and voltage in the right column.

Hi Carrie,

How fast is your pulse and what's the bandwidth of your oscilloscope?
An image of what you see on the oscilloscope would also be useful.

Hi,

Here are my recommendations

1) Do you have the appropriate licenses to run those measurements?

2) Are you running the latest firmware and application versions? If not update and try again.

3) If the above don't work, restore the OS and try again.

Hi Doug,

The issue is that the TCA-BNC is 50 Ohms only and the P6139A requires 1 MOhm termination.
For this reason, you should use the TCA-1MEG adapter instead: https://www.tek.com/en/manual/tca-1meg-2

Hi Ludovic,

I believe 5.1 is the newest version that can be installed on a TLA running Windows 2000: https://www.tek.com/en/support/software/application/tla-application-software-v51-sp1
