Hello,<br> <br> I apologize, but we are unable to verify the previous poster's unit and related information without the serial number of the unit associated with that post.<br> Additionally, Tektronix is unable to share purchase and identifying information related to other customers without their consent.<br> <br> If you believe you were sold a product in error by a third party (i.e. via ebay), you would need to return the product to that individual or discuss proper action to address your concerns with that individual.<br> <br> I understand that you have returned the instrument to the seller. If you purchase a used or new item via an independent seller, rather than direct through Tektronix or through a licenses distributor, we cannot guarantee the functionality or validity of such sales/product and can only recommend the instrument be evaluated by our Service Center to address any operational concerns/malfunction.<br> <br> I apologize that we cannot provide more assistance related to this issue.

You are correct that if you are using a communication port (USB) to use software, you will not be able to use the LAN port for triggering.<br> The best method for triggering, in this case, would be to purchase the TSP-LINK accessory and use either TSP-LINK or the Digital I/O.<br> If this isn't available, you could use a Digital I/O line from your 2450 to send a trigger to signal.<br> I have not tried this operation, however, so there may be some nuances to ensuring a spliced cable will send the appropriate signal to the trigger input.<br> Ultimately, I would recommend purchasing the accessory for the most straight forward method of triggering.

Hello,

To remove a license from a KickStart installation, you will need to:

1. open the software

2. click the license manager (key icon)

3. select the license in the list

4. click the Remove License button

5. save the exit key on your PC

You will then want to follow the instructions provided in the 'How to Check In a License' video linked below.

https://www2.tek.com/slam/sl_help_ui.videos?p_vid=538101

Once the license is checked in, it will be available for use on another PC.

You would then want to install the KickStart software on the new PC, open the license manager in that installation and copy the Host ID at the top of the window.
You can then follow the instructions in the video for 'How to Check Out a Floating License'.

When you've saved your new license file on the new PC, you can install it in KickStart through the license manager window, Install License button.

How do I transfer a KickStart license from one PC to another?
I have it installed on my lab PC currently, but need to use the license on a different computer.

Hello,

Due to the complexity of issues related to our PCT and similar systems, I would recommend generating a support case with our Applications Engineers.
However, I have found that you already have a case open with our support team. One of our engineers should be in contact soon to assist with your request.

Here is some additional information related to your request:

There’s 2 levels of communication here. Unlike with TSP link or TSP net where we can directly reference the nodes in the system and the lead node handles divvying out the responses, we have to explicitly tell the 6221 to communicate back and forth with the 2182A before communicating with the PC.

The SYST:COMM:SER:SEND sends a command to the 2182A. If that command is a query like TRAC:DATA? The 2182A places the requested information into the output buffer of the 2182A. The 6221 still has to read that information with the SYST:COMM:SER:ENT? Command which grabs the info from the 2182A output buffer and puts it in the 6221 output buffer so that it can be read to the PC. The SYST:COMM:SER:SEND command itself is not a query, nothing is put in the output buffer of the 6221, so when you try to read in python, there’s no response to read from the 6221 and an error is produced.

The code should do the following:

Write(SYST:COMM:SER:SEND “TRAC:DATA?”) – tell the 6221 to tell the 2182A to put the data in its output buffer

Query(SYST:COMM:SER:ENT?) – tell the 6221 to check for output from the 2182A and put the response in the 6221 output buffer where we can read it.

Hello,

This sounds very much like the Delta Mode operations available to the 6221/2182A.
This mode creates a system of instruments with TLink and RS-232 between the instruments and sets the 6221 as the 'master' node.
All control operations and data will be handled on this unit, while the 2182A would only be used as a 'software' controlled voltmeter.
Typically, this removes any ability to communicate directly with the 2182A and all data would appear from the 6221 through that link.
I am not sure what additional handshaking occurs through the delta mode backend code to allow for this, unfortunately.
I have shared this post within our development group and hope others will comment with information that may be helpful to you.
 

Hello,

Due to the complexity of this request, please submit a support case and one of our engineers will be able to address your question more thoroughly.

Thank you

Hello,

If your commands/code for the Model 2000 is performing as you require, you can also use the Model 2000 Emulation command set (Menu > System Settings > Command Set) to allow the DMM6500 to act as a drop-in replacement until you develop new code designed for the DMM6500.

However, if you would like to optimize commands for the DMM6500, it seems that you should only need to add an NPLC designation to make a significant impact on the speed of your measurements.
There are several settings that we typically recommend reviewing/modifying to optimize speed vs accuracy (filter, manual range, etc), but NPLC tends to be the largest contributor.
You can find more about this SCPI command on page 12-99 of the Reference Manual:
https://www.tek.com/en/tektronix-and-keithley-digital-multimeter/dmm6500-manual/model-dmm6500-6-1-2-digit-multimeter-3
If you are looking to initiate your measurements (number defined the the SENSE:COUNT command) and then report the latest, you can use the :MEAS? command.
If you only want to take a single initiated measurement and report that latest reading, you can use the :READ? command.
If you want to take multiple readings and report them all, you can use :INIT then :TRACE:DATA? commands.
Please review these commands and required arguments for each in the manual linked above.
Since you are using a filter, there will be some delay time to collect all of the averaged readings and calculate the appropriate reporting value.
These filters can dramatically impact speed and total measurement time.
Overall, total test time and reading speed will depend on several factors and filters can contribute to this depending on their configuration.
 

Hello,

After reviewing the block diagram, it isn't clear to me what is failing.
However, since the driver is developed and supported by National Instruments, you would need to contact them to resolve any issues with the Initialize block itself.
I apologize that I can't provide further assistance.
