Specifications for the Tektronix AFG3021B Arbitrary Function Generator

• USB client port on the back and a USB host port on the front.
• 25 MHz sine wave output.

Programming Syntax

• The reference manual for the AFG3000 series explains the command sequences. Notice the SCPI compliance.

Detecting and Initializing

• usb_devices_raw.py uses PyVisa to find all the IO devices. Notice the USB list, if the USB instruments have been switched on and connected.
• usb_devices.py searches through all USB devices and returns a handle to the scope with the serial number specified. It also returns a handle to the AFG3021B with the specified serial number. Distinguishing with particular serial numbers enables one to use multiple identical instruments.
• initialize_fg_scope.py initializes both devices to compatible operating conditions. initialize_fg_scope_commands.txt contains the actual commands determined from the programming manual.
