The oscilloscope is not an autonomous system. You need a probe to measure the sig-
nal, and the probe has a limited bandwidth, too. The combination of oscilloscope and
probe creates a system bandwidth. To reduce the effect of the probe on the system
bandwidth, the probe bandwidth should exceed the bandwidth of the oscilloscope, the
recommended factor is 1.5 x oscilloscope bandwidth.
See also: Chapter 3.2.2, "Effect of the Bandwidth Filter", on page 45.
For FFT analysis, the channel bandwidth also determines the frequency range dis-
played in the spectrum (see "Frequency range" on page 110).
"Full"
At full bandwidth, all frequencies in the specified range are acquired
and displayed. Full bandwidth is used for most applications.
"x MHz, x kHz"
Frequency limit. Frequencies above the selected limit are removed to
reduce noise at different levels. Limited bandwidth is indicated in the
channel label.
Remote command:
CHANnel<m>:BANDwidth on page 307
Invert
Turns the inversion of the signal amplitude on or off. To invert means to reflect the volt-
age values of all signal components against the horizontal display center. Inversion is
indicated in the waveform labels by line above the channel name.
Inversion affects only the display of the signal but not the trigger. For example: if the
oscilloscope triggers on the rising edge, the trigger is not changed by inversion, but the
actually rising edge is displayed as falling edge.
Autoset does not reset inversion. In spectrum mode, the function also inverts the input
channel signal, not the spectrum.
Remote command:
CHANnel<m>:POLarity on page 307
Offset
Sets an offset voltage that is subtracted to correct a signal with DC component. The
vertical center of the selected channel is shifted by the offset value, and the signal is
repositioned within the diagram area. Negative offset values move up the waveform,
positive values move it down.
Remote command:
CHANnel<m>:OFFSet on page 306
Deskew
Sets a delay for the selected channel.
Deskew compensates delay differences between channels caused by the different
length of cables, probes, and other sources. Correct deskew values are important for
accurate triggering. The propagation delay can lead to a non-synchronous waveform
display. For example, a signal on a coax cable with of 1 meter meter has a propagation
delay of typically 5.3 ns.
