SDS5000X Series Digital Oscilloscope User Manual

Coupling

 DC: All of the input signal frequency components are passed to the display.

 AC: The signal is capacitively coupled. DC signal components are rejected.

See the datasheet for details of the cut-off frequency.AC coupling is

suitable for observing AC signals with DC offset, such as power ripple.

 GND: The channel is grounded by an internal switch. GND coupling is used

to observe the zero offset error of the analog channels, or determine the

source of noise in the waveform (from signal or from oscilloscope itself)

Bandwidth Limit

Full bandwidth can pass through signals with high frequency components, but

it also means that noise with high frequency components can pass through.

When the frequency component of the interested signal is very low, better

signal-to-noise ratios (SNR) can be obtained by turning on a bandwidth limit.

The SDS5000X provides two bandwidth limit options: 20 MHz and 200 MHz.

Probe Attenuation

The SDS5000X provides 1X, 10X, 100X and custom probe attenuation factor

options. The custom values can be between 10

-6

~10

. The oscilloscope will

automatically convert the vertical scale according to the current probe

attenuation factor. For example, the vertical scale of the oscilloscope under 1X

attenuation is 100 mV/div, and the vertical scale will be automatically set to 1

V/div if the probe attenuation is changed to 10X. If a standard probe with

readout terminal is connected, the oscilloscope will automatically set the probe

attenuation to match the probe.
