54 AFG3000 Series Quick Start User Manual
Set up Load Impedance
The output impedance of the AFG3000 series is 50 Ω. If you connect a load other than 50 Ω, the displayed Amplitude,
Offset, and High/Low values are different from the output voltage. To make the displayed values same as output voltage,
you need to set load impedance. To set the load impedance, use the Output menu.
Quick Tips
■ The load impedance is applied to the amplitude, offset, and high/low level settings.
■ When dBm is specified for output amplitude units, the amplitude units setting is automatically changed to V

if you
select high impedance.
1. Push the front-panel Top Menu
button, and then push the Output
Menu bezel button. The Output Menu
is displayed.
2. Push Load Impedance to display the
Load Impedance submenu.
3. To adjust the load impedance, select
Load.
4. You can set the load impedance to any
value from 1 Ω to 10 kΩ.
5. When the load impedance is set to
other than 50 Ω, the set value is dis-
played in the output status.
