Keysight E8491B IEEE 1394 PC Link to VXI User Guide 57Using this Chapter VXI Programming Using the IEEE 1394 Serial BusStoring Readings in Shared Memory - Keysight VISA ExampleThis example uses the E1410 VXIplug&play driver to configure the multimeter,take the readings, and store them in E8491B shared memory. Keysight VISAfunctions are used to transfer the readings from shared memory to the PC.// SHAR_VISA.CPP - This program demonstrates how to access the// E8491B’s shared memory. The program stores readings taken// by the E1410 multimeter in E8491B shared memory, and then// transfers those readings from shared memory to the computer.#include "hpe1410.h"// include the driver header file#include "visa.h"#include #include #include // project files: SHAR_VISA.cpp, hpe1410.lib, VISA32.lib// specify the addressing path to the multimeter#define E1410 "VXI0::24::INSTR" // E1410 path#define E8491 "VXI0::0::INSTR" // E8491 path// check for instrument errors#define INSTR_ERROR 0xBFFC0D07Figure 3-4 Storing Readings in Shared Memory.DUTReadings are taken and transferred from theinstrument to E8491B shared memory overthe VXI backplane.Readings are transferred inblocks from shared memory
