Is the Tektronix MDO (mixed-domain) series compatible with Quick Control Function Generator commands?

I am using the Tekronix MDO4024C oscilloscope that has a built-in MDO4AFG function generator. I am able to control the oscilloscope functionality of the instrument via the Quick Control Oscilloscope commands, but am unable to utilize the Quick Control Function Generator commands. I am using the following drivers: TekVISA and DPO2000, DPO3000, DPO4000 IVI Driver. I try the following code:

f = fgen;
f.resources

f = fgen('USB0::0x0699::0x0456::C013976::INSTR', 'tkdpo2k3k4k'); % Driver and instrument
selectChannel(f, '1');

I recieve the following error:

Error using instrument/FGen 
Failed to connect to instrument, please check instrument connection.

Error in fgen (line 62)
obj= instrument.FGen(varargin{:});

Error in demo_quickcontrol_fgen (line 92)
f = fgen('USB0::0x0699::0x0456::C013976::INSTR', 'tkdpo2k3k4k'); % Driver and instrument

Thank you!

Hi David,

Yes, the Tektronix MDO series is compatible with quick-control function generator commands. The "Tektronix oscilloscope instrument driver" can be used with MDO 4000 series oscilloscopes. Refer the following documentation for information about the driver:

https://www.mathworks.com/hardware-support/instrument-control-toolbox/tektronix-mso-dpo-mdo-3000-and-4000-oscilloscopes-from-matlab.html

All Tektronix oscilloscope models that have a computer interface are supported by the "Instrument Control Toolbox".

The error you are facing could be due to the TekVISA driver. Uninstall and reinstall the TekVISA driver and, if the issue still persists, try installing Agilent's or NI's VISA drivers. Refer the following link to dowload the hardware support packages for Agilent's or NI's VISA:

If the issue still persists, troubleshoot the VISA interface by following the instructions given in this documentation: https://www.mathworks.com/help/releases/R2020a/instrument/troubleshooting-ivi-visa-and-the-quick-control-interfaces.html
