Vertical Axis Setting - Contec DIG-100M1002-PCI User Manual

Vertical Axis Setting

Resolution
The resolution is the number of bits used to express an analogue signal as a digital value.
With high resolution, the range of the voltage si divided finely, thus the analog value can be converted
into digital value more accurately.
This product has a resolution of 10 bits, its range of digital value is from 0 to 1023.
Channel
The channel shows each point that is possible to input analog signal.
Please refer to the description of "3. EXTERNAL CONNECTION-How to connect the connectors-
Connector Pin Assignment"for each channel number.
For that the AD converter is installed in each of the two channels for this product, the simultaneous
sampling is possible.
An arbitrary point can be digitized by setting the channel with software.
Range
The range is a range of the voltage that can be digitized.
This product has the following ten kinds of ranges, the waveform of the analog signal can be digitalized
by selecting an appropriate input range according to the voltage range of the input signal.
The input range is mainly described in a full scale range for CONTEC digitizer.
Input range
±20V
±10V
±5V
±2V
±1V
±0.5V
±0.2V
±0.1V
±0.05V
±0.02V
Offset
The offset function is a function to shift the voltage of the entire input signals up and down.
When the input signal consists of direct current (DC) element and alternating current (AC) element, the
precision necessary for the observation of the AC element might not be obtained even if the input range
is regulated.
In this case, the input range can be effectively used by adjusting the offset to make the center of the AC
element of input signal become 0V.
