Configuring Agilent 33220A function generator in pulse mode

[LTBALAZS]

Hi there,

I made a simple code that should be able to change duty cycle.
After running my code the display of Agilent 33220A should look like in the picture i attached.:


Desired settings: Pulse mode, f=1kHz, Amplitude=5Vpp, Offset, 2,5V
Could someone please tell me how i could change Dty Cyc in my labview code?

Kind regards,

Balázs

The instrument is doing EXACTLY what you told it to do. You set the frequency for 1kHz. The pulse period of 1 kHz is 1 msec. You set the pulse width to 0.99998 msec. The duty cycle is Width/Period*100%. Ergo in your case (0.99998/1)*100% = 99.998%

You didn't specify what duty cycle you want. For example, if you want a 50% duty cycle you need to change the Pulse Width setting to 0.0005 (i.e., 0.5 msec)
