To Output Noise
You can configure the instrument to output noise in the following ways.
•
In the Continuous Setting Interface (
drop-down button to select "Noise".
•
In the Continuous Setting Interface (
Preview/Selection" area and then select Noise in the displayed built-in waveform
selection menu.
•
Press the front-panel
In the setting interface for Noise, you can set the following parameters to create
different noises as desired.
Amplitude/High Level
Click or tap the Ampl/HighL button to set the parameter to "Ampl". "Ampl" is now
highlighted. Click or tap its input field and use the pop-up numeric keypad to set the
amplitude for noise. Available units for amplitude include Vpp, Vrms, and dBm (not
available in HighZ) The amplitude for noise is 4 Vpp by default. The available range is
related to the "Impedance" setting.
•
HighZ: 2 mVpp to 4 Vpp.
•
Load (50 Ω): 1 mVpp to 2 Vpp.
Click or tap the button again to toggle the parameter to "HighL". High Level = Offset
+ Amplitude/2. The high level range is related to the low level setting value. That is,
high level minus low level cannot exceed the current range of amplitude.
Offset/Low Level
Click or tap the Offset/LowL button to set the parameter to "Offset". "Offset" is now
highlighted. Click or tap its input field and use the pop-up numeric keypad to set the
offset for noise. The range of offset is limited by the "Impedance" and "Amplitude/
High Level" setting. The default offset is 0 Vdc.
Click or tap the button again to toggle the parameter to "LowL". Low Level = Offset -
Amplitude/2. The low level range is related to the high level setting value. That is,
high level minus low level cannot exceed the current range of amplitude.
TIP
The "Ampl" and "Offset" buttons appear at the same time, so are "HighL" and "LowL" buttons.
For example, selecting "Offset" automatically toggles the "Ampl/HighL" parameter to "Ampl".
