Re: TekScope Utility Support

No there is not. While the scope can fill up a 10M record length (about 10 MB of data, 8-bit per sample * 10M samples) in only 2ms, it can only offload that data to a PC at maybe 10-30 MB/s plus add in the overhead of fetching the scaling factors to turn that data into floating point voltage values ...

Re: TekScope Utility Support

Do you have the latest firmware on your scope? The DPO4K series has had several commands added to its command set since launch and TekScope Utility makes use of some of these commands. Make sure your firmware it up to date. If you still have timeout issues, can you capture an IO Trace and attach it ...

Re: TekScope Utility Support

Hmm... I will need to get in front of an MSO5 and checkout what you are seeing. Just to make sure I understand this correctly, are you using the scope with the colors set to inverted? If so, are you saying that the grid is perfectly visible when you are using the scope, but in the saved image the gr...

Re: Oscilloscope TDS1012B.Getting a waveform in C ++.

Hi Yaroslav, You might refer to the example C# NI-VISA Get Waveform . It's not C++, but C# syntax is very similar to C++ so it shouldn't be too difficult for you to follow and it will at least give you an idea of the commands you need to use to fetch the waveform and the methodology. Since you are i...

Re: TekScope Utility Support

OK, for series 5 MSO scopes the HARDCopy command will not return the screenshot data. To grab screenshots from the 5 Series you will want to use :SAVE:IMAGE <filename> to save the screenshot to the scope's hard drive, then query *OPC? so you know when it has finished. After that you will want to use...

Re: TekScope Utility Support

Hi gone4fishin. What model scope are you using and what interface. Timeout is usually a problem with transferring hard copies over RS-232 due to the slow data rates and large file size. TekScope Utility transfers hard copies over RS-232 by performing multiple reads in a loop until all bytes are read...

Re: Can I empty the fast frame memory continually to pc

No, continuous memory dumping to the PC is not possible. You will need to wait until all the frames are full and the acquisition stops, then you can transfer the data to the PC and start another acquisition. Fast Frame works by segmenting the high speed acquisition memory into Frames. Each time a tr...

Re: TEKVISA doesn't Detect RSA306

Hi tiktek. That is correct, you will see the device identified as SignalVu-PC as it is SignalVu-PC you are communicating with which in turn controls the RSA306 hardware. You will never see RSA306 identified in VISA.

Hi Vicentiu Neagoe,

In OpenChoice Instrument Manager you need to click the Search Criteria button and make sure that LAN and USB are turned on, else they won't show up in the list.

Re: TekScope Utility Bug Reports

Hi Lars, I was able to look into your TDS3000 hard copy transfer issue yesterday. On a TDS3054C the image transfer over Ethernet worked just fine. Then I noticed you were using a B model. I managed to find a TDS3054B and try it and I saw the same issue as you. Following the IO Trace I could see that...

Re: MDO4104-6 Waveform Data Transfer Speeds to PC

Hi, The speed issue has much less to do with the Ethernet adapter's speed and much more to do with the instrument's processor's speed. The CPU in the MDO4K isn't fast enough to saturate gigabit Ethernet. Currently, only the Windows based scopes (and scopes capable of running windows, a la MSO 5 and ...

Hi lars and everyone. I have a new build in the works (Sorry for the delay. I've been short on time) that will address the .CSV commas in the decimal place issue and will add MSO6 support. Don't think I'll get that TDS3000 Ethernet issue fixed though. I ran into similar trouble with the TDS3000 over...

Re: Free Software: TekScope Utility

This program uses the IVI standard VISA.NET interface to keep the program VISA vendor agnostic. Unfortunately TekVISA does not contain a VISA.NET implementation hence why TekVISA does not work. TekVISA needs to be updated to support the VISA.NET interface.

Hi Lars, Thank you for reporting those. I will take them into consideration for a future update. The decimal setting should hopefully be something I can take care of with some settings in the .NET framework. The TDS3000 Ethernet issue... that instrument over Ethernet has proven difficult.

Re: DPO4104 Oscilloscope - Saving .csv Multiple Times in C#

Hi Jonathan, On line 43 of your code it says TVA.Write("DATA:SOU CH1, CH2"); This is invalid. While on Windows based scopes you may set DATA:SOURCE to more than one item at a time, on the DPO4104 you cannot. Change it to TVA.Write("DATA:SOU CH1"); The rest of it looks pretty good. I don't have a sco...

Hi Jonathan, When you query the data from the scope with the CURVE? query, the data gets sent back with the block header (#45000 for example) followed by the raw data itself. After you have read all the data you will need to do one more read to read the return line character "\n" that the instrument...

Hi akasharma, I have never tried controlling the scopes from VBA, but I've done a lot of scope programming so I'm familiar with the common pitfalls.
