Execute:

10 OUTPUT 70915;"*CLS"	!Clear all switchbox status
	structure.

20OUTPUT 70915;"STAT:OPER:ENAB 256"!Enable Scan Complete Bit to set bit 7 in Status Register.

30	OUTPUT 70915;"*SRE 128"	!Enable bit 7 of Status Register to
		assert SRQ.
40	OUTPUT 70915;"TRIG:SOUR EXT"	!Set to external trigger mode.
50	OUTPUT 70915;"SCAN (@100:103)" !Select channels to be scanned.
60	OUTPUT 70915;"INIT"	!Start scanning cycle.
70	WHILE NOT BIT (SPOLL(70915),7)	!Waiting for scan complete.

80PRINT “DO OTHER OPERATION HERE” !Enter program lines for computer to do other operations.

90 END WHILE

100PRINT “INTERRUPT GENERATED” !Program goes to this line after interrupt is generated by a completed scanning cycle.

110END

!Terminate program.

Comments Channel List Can Be Extended Across Boundaries. For multiple module switchbox instruments, the channels to be scanned can extend across switch modules. For example, for a two module switchbox instrument, SCAN (@100:203) will scan all channels of both Microwave Switch modules.

Setting Multiple Continuous Scans. Use ARM:COUNt number to set from 1 to 32767 scans. Use INITiate:CONTinuous ON to set continuous scanning.
