RZ
Flatter frequency response in 2nd Nyquist region than
DNRZ/NRZ (but less power than Doublet mode). Limited
to f
sample
> 1 GSa/s
Attention!: does not return to zero single ended. (Both
signals of the differential output return to a level slightly
above the positive fullscale level, this is removed when
used with AC path or Balun.)
1.5.3 Delay Adjust
In order to compensate for e.g. external cable length differences as well as the initial
skew, channel 1 and channel 2 can be independently delayed with a very high timing
resolution.
Setting the variable delay of channel 1 to 10 ps has following effect:
 Direct Out1 (or Amp Out1, if selected) is delayed by 10 ps with respect to
following signals: Sample Clock Out, Sync Marker Out1, Sync Marker Out2,
Direct Out2 (or Amp Out2, if selected), Trigger / Gate Input, Event Input
 Sample Marker Out1 is delayed by 10 ps with respect to following signals:
Sample Clock Out, Sync Marker Out1, Sync Marker Out2, Direct Out2 (or Amp
Out2, if selected), Trigger / Gate Input, Event Input
Modifying the variable delay of one channel always affects the delay of the Analog
Output AND the Sample Marker of that channel.
