The chart on the left shows a voltage sinusoidal
signal with amplitude 100mVrms
(282mVpp) acquired by a voltage channel
with 100Vrms (282Vpp) full-scale.

The chart on the left shows a voltage sinusoidal
signal with amplitude 100mVrms
(282mVpp) acquired by a 200Vrms (564Vpp)
full-scale voltage channel.
The chart on the left shows a voltage sinusoidal
signal with amplitude 100mVrms
(282mVpp) acquired by a 700Vrms (1974Vpp)
full-scale voltage channel.
You can see here that the channel is noise-free: the only
noise being quantization (± ½ LSB), which is intrinsic in
analog to digital conversions.
LSB = 1974V/2 16 = 30mV
Noise = ± 15mV

The chart on the left shows a square waveform
with amplitude 100mVrms (282mVpp)
acquired by a 100Vrms (282Vpp) full-scale
voltage channel.
The chart on the left shows a current sinusoidal
signal with amplitude 50mArms (141
mApp) acquired by a 150Arms (IMAX=424App)
full-scale current channel.
The chart on the left shows a current sinusoidal
signal with amplitude 50mArms (141
mApp) acquired by a 30Arms (IMAX=84App)
full-scale current channel.
