To Output Noise
Press Setup1 to open the waveform setting menu. Press Wave and select “Noise”.
At this point, you can output noise signal with specified amplitude.
1. Set the amplitude
Press Amp 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 “
Parameter Setting Method”.
2. 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). For the setting method,
please refer to the introduction in “
Parameter Setting Method”.
Note: The offset value only contains three effective digits. For example, when
the amplitude is set to 30 mVpp (the impedance is 50 Ω), the offset range
calculated is from -1.235 V to 1.235 V, while the actual offset range is from -1.23
V to 1.23 V.
