    2.4 Analog Input Signal Connection The PCI-1202/1602/1800/1802 can measure single-ended or differential type analog input signal. Some analog signal can be measured in single-end or differential mode, but some analog signal only can be measured in one of the single-ended or differential mode. The user must decide which mode is suitable for measurement.

    3. I/O Control Register 3.1 How to Find the I/O Address The plug&play BIOS will assign a proper I/O address to every PCI-1800/1802 card in the power-on stage. The P180X_DriverInit(..) can detect how many PCI-1800/1802 cards in the system. Then the P180X_DriverInit(..) will detect the I/O address of these cards. The P180X_DriverInit(..) is supported in NAPPCI/dos, NAPPCI/w31, NAPPCI/w95 and NAPPCI/wnt.

  • Page 33: The Assignment Of I/O Address

    3.2 The Assignment of I/O Address The plug&play BIOS will assign the proper I/O address to PCI-1202/1602/1800/1802. If there is only one PCI-1202/1602/1800/1802, the user can identify the board_1. If there are two PCI-1202/1602/1800/1802 cards in the system, the user will be very difficult to identify which board is board_1.

    5. M_Function Some real world applications have to send out the pre-defined pattern to the external device and measure the output responses for analysis. The user need one arbitrary wave form generator and one high speed A/D converter. The M_Functions, provided by PCI- 1202/1602/1800/1802, can send out the user defined arbitrary waveform and perform the A/D conversion at the same time.

The M_FUN_1 will automatic to compute the sine wave output image. The M_FUN_2 is designed for arbitrary waveform generation, so the user can prepare their waveform for M_FUN_2.

Therefore the D/A output waveform will be distorted sometimes. Refer to Figure 5-5 for details. If the user has to generate the periodic wave form such as sin, cos …, and the analysis is similar to spectrum analysis, this type of output distortion will cause little trouble.
