All outputs have with the capability to test all of the active components on 12-bit resolution, and can source or sink 10 mA at ±10 V. the board, including the output switches. This test For offline testing, the analog outputs can be disconnected scheme utilizes an on-board analog-to-digital converter from the external circuits. (ADC) and multiplexers, as shown in Figure 1. FUNCTIONAL CHARACTERISTICS Memory Testing: This product is designed with dual-port on-board registers that may be tested by VMEbus Compliance: The analog output board is a executing a user-defined memory test program for standard double height printed circuit board which is additional performance verification. compatible with the VMEbus specification (Rev. C.1). VMEbus A16:D16 System Reset: Application of the system reset signal via the VMEbus initializes the board into a state with all Board Address: The physical address for the board analog outputs disconnected from the output. may be selected by on-board jumpers. VMEbus address lines A07 through A15 are decoded for board selection. VMEbus Access: Address modifier bits are jumper-selected and decoded to support both nonprivileged short I/O, supervisory short I/O, or both.
