This program uses the E1411B multimeter and the E1351A FET
multiplexer to perform high-speed scanning. The program configures the
multimeter for high-speed measurements and downloads a scan list to the
FET multiplexer. The program requires that the analog bus and digital bus
cables be connected between the multimeter and the multiplexer.
/* E1411_SC.CPP - This program uses the E1411B to scan five E1351A FET */
