Leveled - LeCroy WavePro 7 Zi series Operator's Manual

Figure 5-10. Simulation result showing transfer function of the digital low-pass filter and 3-tap EQ (boost)
filter, set to 8.2 MHz cutoff frequency and 3.2 dB boost.
There are no additional conditions to produce leveled data. The threshold is calculated and subtracted even if the
equalization could not be applied for the reasons previously explained.
The slicer uses a fixed hysteresis around zero, which corresponds to half a division (+ and - 1/4 division) when not
vertically zoomed. (Remember that the slicer works on Leveled data, so zero is the correct threshold; the
dynamically computed threshold has already been subtracted.) This means a peak must cross zero and exceed it
by a quarter of a division or it will be ignored, as if it were noise after the previous crossing. A signal that is four
divisions high (half of full scale) should have no problem meeting this requirement.
