Register-Based Programming 139Appendix B
If bit 12 and either bit 13 or 15 is set during the same write, an ABORT
followed by an INIT is executed. If bit 12 is “0”, either bit 13 or 15 is set and
the previous measurement completed, an ABORT followed by an INIT is executed.
If bits 12, 13 and 15 are all “0”, no action is initiated.
bit 7 SOFT
SAMPLE
software sample: 0 = IMMediate disabled, 1 = IMMediate enabled.
bit 8 POS_NEG External sample slope: 0 = NEG, 1 = POS.
bit 9 EX_SAMPLE 1 = EXTernal sample is an external source you must input on the “Sample” pin on the
front panel D-subminiature connector. 0 = EXTernal sample disabled.
bit 12 ABORT 1 = aborts measurement and flushes all reading data in all memory. The bit is set to “0”
when the digitizer is initiated.
bit 13* INIT
with 30 msec
delay
This bit will initiate measurements after a 30 msec delay when it is set to “1”. It is set to
“0” when pre-trigger readings are complete.
bit 15* INIT IMM This bit will initiate measurements immediately when it is set to “1”. It is set to “0” when
pre-trigger readings are complete.
