4.4 Digitalization and signal path
Data rate
QuantumX measurement modules with the suffix B, like
the MX840B, for instance, have decimal data rates such
as 600, 1200, ....19,200 S/sec available, in addition to
classic data rates such as 500, 1000, .... 100,000 S/sec.
When there are several modules in a group, the selected
data rate domains must be identical. Catman® or MX
Assistent software allows toggling the sample rate do
main, e.g. From „Classic“ to „Decimal“.
Signal paths
Synchronizing the acquisition of all channels allows sig
nal analysis of all recorded measurement data at the
same time.
It often happens that some sensor signals should be
made available in real time, in parallel with the data ana
lysis of highfrequency signals (e.g. 100 kS/sec per chan
nel), i.e. deterministically, with a moderate data rate (e.g.
1 kS/sec or 1 ms control loop) and with a minimum
latency time (e.g. max. 1 ms).
To do this, the modules need to be connected with each
other via the FireWire bus and the signals need to be
made available "isochronously", for example, to be com
puted and/or output via another module (analog, CAN,
EtherCAT).
To give this parallel operation optimum support, each
QuantumX measurement channel generates two signals.
