SDS2000X HD Series Digital Oscilloscope User Manual
i n t . s i g l e n t . c o m 5 9
Activating a channel recalls the channel dialog box, displaying more parameters:
A. Turn channel on/off
B. Coupling (DC, AC, or GND)
C. Bandwidth limit (Full, 200 MHz, or 20 MHz)
D. Probe settings including attenuation (1X, 10X, 100X, or
custom) and probe check.
E. Set the label text. Click to recall the label setting. Users
can customize the text and display of the label
F. Quickly apply a specified operation (Trigger, FFT,
Simple Measure, Cursor, Search, DVM, Histogram,
Mask Test, Counter, and AWG) to the current channel
G. Impedance
H. Units for the channel
I. Deskew
J. Enable/disable invert
K. Trace visible/hidden
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)
