Clear All Command is not working

Hello,

I am working on a python script to control various instruments in our lab, including a DPO 7354 oscilloscope from Tektronix. I have not had problems with other commands listed in the programming manual for our scope, but we have yet to get the clear all command to work. I have attached the manual that we are using as a reference. I have also attached a screen capture that has what we are sending to our scope. If anyone can help that would be appreciated. 

Best,
Cadence

Interesting challenge! Have you tried sending a raw SCPI command string like "*CLS" directly? Tektronix oscilloscopes can be finicky. Also, ensure proper termination characters (e.g., "\n"). It's like trying to navigate the Pacman 30th Anniversary maze with wrong coordinates! Manual referencing is great, but direct command testing helps. Hope this gets you clearing that scope screen.
