read configuration values from TDS3000 series Scope

[rick2047]

Hello,

I am using the instrument drivers provided by tek for the TDS3000 scope to control the instrument. Although there are many options to provide configurations to the instrument, I am unable to figure out how to retrieve the current configuration of the instrument. I want to make it so that when I start my VI it reads the current configurations from the instrument and then sets the initial values (using a property node) to those values. Basically I am looking for a way to synch my VI with the scope. How may I do that?

The drivers's don't include a Get X Setting VI?  If not, you will need to look up the programmer's manual and possibly create your own querry VIs.

No they do not have any query VIs. Where can I get examples of making my own query VI?

How to query the instrument is explained in the manual.

Your idea of getting the current settings just to update some front panel controls is pretty unusual. Normally, you just don't care since you'll be setting the instrument the way you want anyway. That is why a driver seldom includes all of the queries. A driver is complicated enough without all of the additional code required.

You will need to lookup the command structure and how the returned data will be formated.  Here's the quick setup.
