AC coupling. A high-pass filter removes the DC offset voltage from
the input signal if the DC component of a signal is of no interest. The
waveform is centered on zero volts.
If AC coupling is set, the attenuation of passive probes has no effect,
and voltage is applied to the instrument with factor 1:1. Observe the
voltage limits, otherwise you can damage the instrument.
DC coupling, the signal passes the input unchanged.
Remote command:
CHANnel<m>:COUPling on page 306
Probe Setting
Selects the attenuation factor of the connected probe. The vertical scaling is adjusted
accordingly, and measured values are multiplied by this factor so that the displayed
values are equal to the actual signal values.
Make sure to set the attenuation factor on the instrument according to the probe being
used. Otherwise, the measurement results do not reflect the actual voltage level, and
you might misjudge the actual risk.
If AC coupling is set, the attenuation of passive probes has no effect, and voltage is
applied to the instrument with factor 1:1. Observe the voltage limits, otherwise you can
damage the instrument.
The menu lists the common attenuation factors. If the required factor is not in the list,
select "User" and set the Probe Factor.
Remote command:
CHANnel<m>:PROBe on page 304
Probe Factor
Sets a user-defined attenuation factor if the probe has an uncommon attenuation, and
the unit (V or A). The setting is available if "Probe Setting" is set to "User".
Remote command:
PROBe<m>:SETup:ATTenuation:MANual on page 305
PROBe<m>:SETup:ATTenuation:UNIT on page 305
Bandwidth
Selects the bandwidth limit. The full instrument bandwidth indicates the range of fre-
quencies that the instrument can acquire and display accurately with less than 3 dB
attenuation.
For analog applications, the highest signal frequency determines the required oscillo-
scope bandwidth. The oscilloscope bandwidth should be at least 3 times higher than
the maximum frequency included in the analog test signal to measure the amplitude
with high accuracy.
Most test signals are more complex than a simple sine wave and include several spec-
tral components. A digital signal, for example, is built up of several odd harmonics. For
digital signals, the oscilloscope bandwidth should be at least 5 times higher than the
clock frequency to be measured.
