Block Parameters

Channel vector

Enter a vector of numbers to specify the input channels. For example, to use the first three analog input (A/D) channels, enter

[1, 2, 3]

The channel numbers can occur in any order. Number them beginning with 1 even if the board manufacturer numbers them beginning with 0. The maximum allowable channel number for this board is 8 (differential-ended) or 16 (single-ended).

Gain vector

To specify the gain, enter 1, 2, 4, or 8 for each of the channels in the channel vector. The gain vector must be the same length as the channel vector. If you enter a scalar, the value is applied to all channels.

The gain is applied to the signal prior to sampling the voltage. After the signal voltage is sampled, the result is divided by the gain to obtain the block output signal value. To avoid clipping, make sure that the amplified gain falls within the range you selected.

Range

From the list, select Bipolar -10V to +10V, Unipolar 0V to +10V, or Unipolar 4mA to 20mA. Choose a range that is consistent with the jumper settings on the board. This range applies to all channels.

Sample time

Enter the base sample time or a multiple of the base sample time.

PCI Slot (-1:autosearch)

If only one board of this type is in the target PC, enter

-1

to automatically locate the board.

If two or more boards of this type are in the target PC, enter the bus number and the PCI slot number of the board associated with this driver block. Use the format [BusNumber, SlotNumber]. To determine the bus number and the PCI slot number, type

getxpcpci

Note that the Device ID of this board is 8133.
