* Filename:       test_dac.c                                                   *

* Author:         Marco Ziglioli (Doctor Stein)                              *

* Date:           12/06/2001                                                 *
5
* Description:    Little test program for Analog Output section of PCI6025E  *
6
*----------------------------------------------------------------------------*
7
* Notes:          Connect a multimeter to DAC1 output (pin 21) and watch     *
8
*                 tension value. Use '+' and '-' on numeric pad to increase  *
9
*                 and decrise voltage                                        *
10
*                 With this program it's possible to point out possible      *
11
*                 offset errors. To correct them no software are written but *
12
*                 in National board package there's the program to calibrate *
13
*                 the board. Otherwise you can see how much is the offset    *
14
*                 and you can compensate it through software value           *
