Table 5-3: Methods for voltage measurement
Method
Note
Single Ended
The level is measured between one input (CHx_IN) and module ground (AGND
or LO on the front side connector)
Differential
The level between two inputs is determined by taking the difference. The follow-
ing combinations of inputs are possible:
CH1 - CH9
CH2 - CH10
CH3 - CH11
CH4 - CH12
CH5 - CH13
CH6 - CH14
CH7 - CH15
CH8 - CH16
The following measurement ranges can be set:
●
7V
●
14V
●
28V
Voltage measurement can be configured with function
rspio2_ConfigureAnalogMeasurement
.
Recording of measurement values is monitored by sequence control (see Section
5.1.13). The setting of the the time interval also determines the conversion time of the
ADC and thus the input bandwith and accuracy that can be achieved. Because of this,
parameter „Sample Interval“ of function
rspio2_ConfigureSampling
is meaningful
even if only one measurement value („Sample Count“ = 1) will be recorded!

Recording of measurement values is started by sequence control (see Section 5.1.13).
The results can be queried with function
rspio2_FetchAnalog
. If you are only inter-
ested in the average value of all the samples recorded, it can be retrieved with
rspio2_FetchAverage
.
5.1.13 Triggering and sequence control
Measurement values are recorded and output of digital bit patterns is monitored by a
central control system. Function
rspio2_ConfigureSampling
can be used to
define the number of „Samples“ that will be recorded or generated. The time interval
between the „Samples“ can be adjusted with this function.
