N432A Remote Operation
At time T3, the condition bit remains 1. The event register is cleared by a query.
Hence, the event register bit and summary bit are set to 0.
At time T4, the condition bit changes from 1 to 0. Since the positive transition
filter is set to detect condition bit changes from 0 to 1, the corresponding bit in
the event register will be set to 0, signifying no event has been logged. The
summary bit is set to 0 as no bit is set in the event register.
At time T5, the condition bit remains 0. Since there is no changes to the condition
bit at this time, no corresponding bit in the event register will be set and the
summary bit is 0.
Consider Case D, where the positive and negative transition filters are set to 1.
This configures the N432A to set the corresponding bit in the event register
whenever there are changes to the condition bit. The enable register is set to 0 to
disable the summary bit to be generated.
At time T1, the condition bit is 0. Since there is no changes to the condition bit at
this time, no corresponding bit in the event register will be set and the summary
bit is 0.
At time T2, the condition bit changes from 0 to 1. Since the positive and negative
transition filters are set to detect any changes to the condition bit, the
corresponding bit in the event register will be set to 1. The enable register is set to
0, which means that the summary bit will not be set.
At time T3, the condition bit remains 1. The event register is cleared by a query.
Hence, the event register bit and summary bit are set to 0.
At time T4, the condition bit changes from 1 to 0. Since the positive and negative
transition filters are set to detect any changes to the condition bit, the
corresponding bit in the event register will be set to 1, signifying an event has
been logged. The summary bit is 0 as the enable register is set to 0.
At time T5, the condition bit remains 0. The event register is cleared by a query.
Hence, the event register bit and summary bit are set to 0.
