Description
The SET-2090 device is an experimental card for NI-SLSC and provides 32 differential inputs. The input
signals can be configured by customers. Each input channel can be tested, conditioned or measured in
different ways. Various inductors, filters, pull-up or pull-down resistors can be used for this purpose. In
standard configuration, the input signals are transmitted directly to the output.
Circuitry
Note Diagram only shows one channel. All components without a labeling, are optional.
The „ Ref. “ Signal form the block diagram below is each connected to the corresponding
Reference Signals on the Front connector. Per connector 4 Reference Signals are
available, mapping each to four differential signals.
For example, the Ref. from Channel P0.0 is connected to the Ref_0 Signal which is on J1
and shared for channel P0.0 to P0.3.
Ref_0 is for channel P0.0-P0.3 Ref_4 is for channel P4.0-P4.3
Ref_1 is for channel P1.0-P1.3 Ref_5 is for channel P5.0-P5.3
Ref_2 is for channel P2.0-P2.3 Ref_6 is for channel P6.0-P6.3
Ref_3 is for channel P3.0-P3.3 Ref_7 is for channel P7.0-P7.3
J1_Spare is for channel P0.0-P3.3 J2_Spare is for channel P4.0-P7.3
All voltages are relative to GND unless otherwise noted.
