B20
Limit to 20 MHz. Higher frequencies are removed to reduce
noise.
*RST:
FULL
Manual operation:
See
CHANnel<m>:POLarity
<Polarity>
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 ground level. Inversion affects only the
display of the signal but not the trigger.
Suffix:
<m>
.
1..4
Selects the input channel. The number of channels depends on
the instrument.
Parameters:
<Polarity>
NORMal | INVerted
*RST:
NORM
Manual operation:
See
CHANnel<m>:SKEW
<Skew>
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.
Suffix:
<m>
.
1..4
Selects the input channel. The number of channels depends on
the instrument.
Parameters:
<Skew>
Deskew value
Default unit: s
Manual operation:
See
CHANnel<m>:ZOFFset[:VALue]
<ZeroOffset>
Sets the zero offset.
Differences in DUT and oscilloscope ground levels may cause larger zero errors affect-
ing the waveform. If the DUT is ground-referenced, the "Zero Offset" corrects the zero
error and sets the probe to the zero level.
You can assess the zero error by measuring the mean value of a signal that should
return zero.
