Output Menu
Table E-9 shows the Output Menu. To access the Output menu, push the
front-panel Top Menu button, and then push the bottom bezel button.
Load Impedance. The output impedance of the AFG3000 series is 50
Ω. If you con-
nect 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.
Noise Add. When you set Noise Add to On, the amplitude of output signal is
reduced to 50%.
CH1 Complement. A dual-channel instrument can be used to generate a differential
signal by programming CH2 to output the complement of CH1.

1. Range: 1 Ω to 10 kΩ.
When dBm is currently selected for output amplitude units, the amplitude units setting
is automatically changed to V

if you select high impedance.
Option buttons & Numeric input.
You can set the load impedance to any value
from 1 Ω to 10 kΩ.
High Z Option buttons. Select high impedance.
Invert
Off On
Selects Invert On to invert a waveform polarity.
Limit High Limit Numeric input.
Specifies the higher and lower amplitude limit.
See Level Meter on page 1-12.
Low Limit
Noise Noise Add
Off On
Selects Noise Add On to add the internal noise
to a waveform.
Noise Level
2
2. Range: 0% to 50% of amplitude setting (V
p-p
) of signal waveform, resolution 1%
The maximum value of noise range is limited by waveform and amplitude range.
Sets the noise level.

3. AFG310x and AFG325x series only.
When CH1 is selected:
Selects External Add On to add an external
signal to the CH 1 output signal.
CH1 Complement
4
4. Dual-channel model only.
When CH2 is selected:
The CH2 waveshape and timing parameters are
copied from CH1, and the CH2 amplitude set-
tings are inverted from CH1.
