Scanning a Switchbox with a Downloaded Scan List

This example shows a FET switchbox connected to multimeter with the analog bus cable and the digital bus cable. The switchbox and multimeter are separate VXIbus instruments. The multimeter has a secondary address of 03, and the switchbox has a secondary address of 04. The triggering is through the digital bus handshake lines, so the scan list is downloaded. The following program illustrates the procedures:

10	DIM Rdgs(1:16)	!Dimension array to store readings
20	OUTPUT 70903,"RST,OPC?"	!Clear the multimeter; *OPC?
		ensures reset is completed before
		program continues
30	ENTER 70903;A
40	OUTPUT 70903;"*CLS"
50	OUTPUT 70904;"*RST"	!Reset multiplexer
60	OUTPUT 70904;"*CLS"
70	OUTPUT 70903;"CONF:VOLT:DC 58.1"!Configure the multimeter
80	OUTPUT 70903;"TRIG:SOUR EXT"	!External trigger source
90	OUTPUT 70903;"TRIG:COUN 16"	!Set for 16 triggers
100	OUTPUT 70903;"INIT"	!Initialize multimeter, wait for
		trigger
110	OUTPUT 70904;"STAT:OPER:ENAB 256"
		!Enable operation complete bit
120	OUTPUT 70904;"TRIG:SOUR DBUS"!Digital bus triggers
130	OUTPUT 70904;"SCAN:MODE VOLT"!Configure for voltage
140	OUTPUT 70904;"SCAN:PORT ABUS"!Enables analog bus
150	OUTPUT 70904;"SETT:TIME MAX,(@100)"
		!Delay for signal to settle before
		multiplexer enables channel closed
		pulse
160	OUTPUT 70904;"SCAN (@100:131)"!Enter scan list
170	OUTPUT 70904;"INIT"	!Close first channel
180	OUTPUT 70903;"FETC?"	!Multimeter retrieves readings
		from mainframe memory when
		scan completes
190	ENTER 70903;Rdgs(*)	!Put readings in array
200	PRINT Rdgs(*)	!Print
210	END
