Has anyone completed a config file for the Rigol DM3068 meter?

Has anyone completed a config file for the Rigol DM3068 meter?

I have found my old DM3068 and made a definition for it:
http://lygte-info.dk/pic/Projects/TestController/Rigol%20DM30xx.txt

The definition support DM3068, DM3058 & DM3058E (If the *idn? line from DM3058E says DM3058 a small modification must be done, if anybody test, please post the result).

I have used the Rigol command set and that was a bad idea, this command set only have a minimum of commands and do not support all meter functions.
It looks like the best support is by using Agilent command set, but I will not use time to change my device file at the current time.
This definition will also be included with the next update.

Just got this working and found something a bit peculiar. The region in the attached file marked with arrows is unstable ... seems to be twitching a little.

Great utility BTW. Thanks for sharing!

That may happen when logging is active, the chart is based on a subset of the logged data and that subset may wary with each update.
The subset is limited by screen resolution, but there is also a hard limit of 5000 points. Zooming is not affect by the limit.

With all that noise, try making a math channel with a low pass filter, that way you can isolate the low frequency component. Using the high pass filter you can isolate the high frequency part (In both cases it will not be perfect). You can also subtract 10 from the data, this way you will have a more sensible scale.
A math channel can be created before you start logging or after you stop logging, but not while logging.

V0.70 is up.

It includes the Rigol definition.
I have improved some slowdowns in the UI when using slow devices.
It has a couple more manual pages (Current values, Table, Chart).
I have added a test/demo function, when starting the program with an empty "Load devices" page it will ask:

Answer Yes and the 3 virtual generators will be loaded and logging started. This means all pages will be enabled and show something.

HKJ,

It looks like there is a bug when using a device with COM/USB ports in V0.70, when on the Current Values tab you get the below errors

It looks like there is a bug when using a device with COM/USB ports in V0.70, when on the Current Values tab you get the below errors

That is the part I have worked on to avoid slow downs, but it looks like I am missing some locks (I do not see the problems on my machine).

I have modified the code slight here:

Still looks like there is an issue. With Bryman BM869s only enabled I get the below errors. With Fluke 289 only enabled it works fine. If I have both the Bryman BM869s and Fluke 289 enabled it work fine.

HKJ,

It looks to be fixed, back to normal. Also are you going to add the Keysight344xxA device file that has system temperature to V0.70.

Thanks,
MikeLud

It works in a way, but adding this line will improve it significantly:
:readmath: formatDouble(value,1,3,1,1)

Without that it do do something like: 3.234E+1

I will include it.

HKJ,

Readmath added.

It looks to be fixed, back to normal. Also are you going to add the Keysight344xxA device file that has system temperature to V0.70.

Thanks for testing.

I have updated the .zip file and added the Keysight with temperature to it, i.e. it is V0.72 now.

HKJ,

The .zip file is still V0.70.

I hope it is updated now.

HKJ,

Same here, still V0.70

I get V0.72 when I download.

Sometimes the webserver is slow to publish when I upload a changed file, it may be due to some caching.

Now seeing 0.72

And the last upload I did was when I wrote "I hope".

Good idea about the LPF ... but not able to get it working. No values are being recorded. I have tried it with Source formula cleared (blank) and also without the Math: portion and also with (sum*(samples-1)+lastValue/samples entered under Source formula.

You use the name of the value you want filtered as you source formula: K34465.VoltageDC
You can, of course, do much more than that, but for just filtering a value you only need that name.

I will hopefully be easier when I publish the documentation for that page.

Any ideas about doing X/Y graphing?
Could be useful in connection with temperature coefficient
measurements on resistors among others.

I have been thinking about it, but not done anything yet.

I will probably have to disable the cursor in X/Y mode.
I may also have to increase the maximum number of points to plot in X/Y mode and this may affect update speed when working with large datasets.

The general issue is that the data on the Y axis will not necessary be a steady increasing value, but may jump around, that is the reason for the above two points.

Can someone do a description for SDL1000X loads because I wouldn't know where to start ?

TIA

I can get your started. Connect the load to the computer, the select the "Load devices" page and right click on the combo box. Select "Create new SCPI..."
Run through the four buttons on that page, if you uses a network connection you need to fill in the IP address.

Then add to the new device file:

#value Voltage V D3
#value Current A D3

#askValues MEAS:VOLT?;MEAS:CURR?

This ought to get your two columns with values from the load.
Next is setting up the load in some mode, we can talk about that if the above works.
