To Output Noise
Press Src1 Setup to open the waveform setting menu. Press Wave and select
“Noise”. At this point, you can output noise signal with specified amplitude.
1. Source
Press Source to turn on or off the signal output.
2. Set the amplitude
Press Amplitude to set the amplitude of the signal. When the impedance is set
to HighZ, the range is from 20 mVpp to 5 Vpp; when the impedance is set to 50
Ω, the range is from 10 mVpp to 2.5 Vpp. For the setting method, please refer to
the introduction in
Set the frequency.
3. Set the offset
Press Offset to set the DC offset of the noise signal. When the impedance is
HighZ, the range is from (-2.5 V+the current amplitude/2) to (2.5 V-the current
amplitude/2); when the impedance is set to 50 Ω, the range is from (-1.25 V+the
current amplitude/2) to (1.25 V-the current amplitude/2).
Method 1:
Rotate or the navigation knob to set the desired DC offset voltage.
Method 2:
Press down and the numeric keyboard is displayed. Use the knob to input
the desired offset value and unit.
Note: The offset value contains three effective digits. For example, when the
amplitude is set to 10 mVpp (the impedance is 50 Ω), the offset range calculated
is from -1.245 V to 1.245 V, while the actual offset range is -1.24 V to 1.24 V.
