Hi,

I was referring to a fresh install of the OS on the computer, not on the scope.

If you are able to communicate with other instruments through LabView but not the DPO5034 and are not able to share the SCPI commands you are sending here, then I would ask you to submit a ticket (remember to include a link to this thread) here: https://www.tek.com/en/support/contact-technical-support
There we will be able to further assist you in private. We will likely need you to share at least some of the SCPI commands you are using, so we can understand the problem and help you.

Hi Randy,

Information online about the Hantek HT25 is limited, but it appears to be an induction/current probe specialized for automotive use.
This type of probe features a different circuit from the one featured in your image (which is more of a passive voltage probe circuit).

With the information I have, I cannot help you with creating a compensation circuit, I would need to know more about the inner workings of the probe or, at least, what impedance it expects to be terminated into.
I would suggest contacting Hantek.

Hi Jeff,

From a quick test with my DSA72004, the max record length is 250 million points, no matter the number of channels enabled (this isn't necessarily true for all oscilloscopes). I would assume this is also true for yours with 30 million points.

If 30 million points is not enough for your needs, you can buy an option to enable higher record lengths. The max one is called 20XL (allows up to 250 million points), but there are others for lower record lengths.
 

To order a part call 1-800-833-9200 opt 1.

Or send an email to buy@tektronix.com

As Jeff said, the record length can be configured on the scope horizontal/acquisition menu, not on DPOJET.

For clarification, the record length is the number of points saved to memory per acquisition. That is to say, a 250 M record length implies that 250 million points are saved to memory per acquisition (the duration of the acquisition being 10 times the configured scale or time/div).

Hi Andre,

You are doing nothing wrong, unfortunately this is currently a known gap in the 2 series MSO.
I have escalated this to our product line team and we are hoping to fix this in upcoming firmware releases.

Hi Jeremy,

The only way I've found to get the units of a math channel when those aren't custom is display:waveview1:cursor:cursor1:hbars:aunits?, this will query the units of the currently selected waveform view. To select a waveform, view you can do display:waveview1:cursor:cursor1:asource math2.

Cursors do not have to be enabled for this work.

Note this will only get you the unit, not the scale, for that you can use the commands we previously discussed.

Hi Jeff,

That is my mistake, I'm sorry. DPOJET does not necessarily update with the firmware.
The latest DPOJET version for the DSA70000B can be downloaded here: https://www.tek.com/en/support/software/application/dpojet-dpo7000-dpo-dsa-mso70000-b-win-xp-v501-0

Hi,

As a starting point I would suggest looking at the following remote control examples: https://forum.tek.com/viewtopic.php?f=580&t=133570
If you have yet to pick a language to use, then I generally suggest Python3.

Those examples might not do the specific things you need, for that you will need to consult the programmer's manual and find the commands you need: https://www.tek.com/en/oscilloscope/mso4000-dpo4000-manual/mdo4000c-mdo4000b-mdo4000-mso4000b-dpo4000b-and-mdo3000-0
To turn on a channel and configure it to full bandwidth, look in the Vertical command group.
For triggering setup, look in the Trigger group. 
For setting up measurements (which can be made visible on the screen), look into the Measurements group.

Hi,

The TDS2000B service manual lists step 33 (page 5-7) as 1.0 V, not -2.5 V.

Hi Jeremy!

The MATH:MATH2:VUNIT? command returns the name of the "Alternate Units" (empty by default, in which case V is used).

I believe the command you are looking for is display:waveview1:math:math2:vertical:scale? or MATH:MATH2:SCALE? (not mentioned in the manual but appears to be equivalent).
