Signal Phase Delays Within The Clipx And Over The Clipx Bus - HBM ClipX Bedienungsanleitung

6.12 Signal phase delays within the ClipX and over the ClipX
bus
The various modules in the ClipX are combined into a number of groups, each
with fixed cycle times. This makes it easier to calculate the total phase delay of
a signal. The following diagrams indicate the phase delays of the various groups
as well as any potential additions you might need to allow for the hardware of
inputs/outputs. To calculate the maximum phase delay of signals running
through more than one group, such as min/max values obtained from calculated
channels, simply add together the phase delays of the respective groups.
Pay attention to the sequencing of the analysis within a group. If source signals
are formed only later in the group, this will double the phase delay until the
result is available.
Phase delays of A/D converter plus digital filter
Some filter frequencies are only possible with a DC amplifier, and are identified
accordingly. The bandwidth with DC and the digital filter switched off (Filter
OFF) is 3800 Hz. The filter phase delay is then 0 ms, meaning the phase delay
of the A/D converter with no filter is 260 μs.
