to 50Ω, the range available is -1.25 V to +1.25 V.
3. To set the impedance
Press Impedance to set the outpuyt impedance of the signal source to “HighZ”
or “50Ω ”.
To Output Noise Waveform
Press Src1Conf to enter the waveform setting interface. Press Wave to select
“Noise”, at this point, you can set the amplitude, offset and impedance of the noise
signal.
1. Output
Press Output to turn the signal output on or off.
2. To set the amplitude
Press Amplitude to set the amplitude of the current signal. For the setting
methods, refer to “
Parameter Setting Methods”. When the impedance is set
to HighZ, the range available is from 20 mVpp to 5Vpp and when the impedance
is set to 50 Ω, the range available is from 10 mVpp to 2.5 Vpp.
3. To set the DC offset voltage
Press Offset to set the DC offset of the current signal. For the setting methods,
refer to “
Parameter Setting Methods”. When the impedance is set to HighZ,
the range available is from (-2.5 V+current amplitude/2) to (2.5 V-current
amplitude/2) and when the impedance is set to 50 Ω, the range available is (-1.25
V+current amplitude/2) to (1.25 V-current amplitude/2).
Note: The offset value can only maintain three effective digits. For example,
when the amplitude is set to 10 mVpp (the impedance is 50 Ω), the offset range
calculated is -1.245 V to 1.245 V, but the actual offset range is -1.24 V to 1.24 V.
