Signal Range The proper setting for the signal range is important in data acquisition e g the input signal may be saturated if the A D gain is too large or the resolution is to small if the signal is at very low level The maximum A D signal range for the PCI 9114 A is 10 volts when the programmable gain value is 1 The A D gain control register controls the maximum signal input range The signal gain is programmable with 4 different levels 1 10 100 1000 or 1 2 4 8 The signal range for the 32 channels is the same for all channels The available signal polarity on the PCI 9114 A is bi polar only however the 16 bit high resolution PCI 9114 A can cover all 12 bit uni polar applications 4 1 3 A D Trigger Source Control An AD conversion is initiated by a trigger source the AD converter will then start to convert analog signals to a digital value With the PCI 9114 A two internal sources can be selected a software trigger or the timer pacer trigger The A D operation mode is controlled by the A D trigger mode register In total there are two trigger sources provided by the PCI 9114 A Different trigger conditions are specified below Software trigger TSSEL 0 The trigger source is software controlled in this mode That is the A D conversion is initiated when any value is written into the software trigger register This trigger mode is suitable for low speed A D conversion Under this mode the timing of the A D conversion is
