Using the extended event register
Changes in the condition register are reflected in the
extended event register (page 6-4).
Example
:STATus:FILTer1 FALL;:STATus:EESE 1;
EESR?;*SRE 8\<PMT>
(Read the response to
:STATus:EESR?
)
Loop
(Wait for a service request)
:NUMeric[:NORMal]:VALue?\<PMT>
(Read the response to
:NUMeric[:NORMal]:
VALue? )
:STATus:EESR?\<PMT>
(Read the response to :STATus:EESR? )
(Return to
LOOP
)
The “
STATus:FILTer1 FALL
” command sets the
transition filter such that Bit 0 (FILTer1) of the
Extended Event Register sets to
1
when Bit 0 of the
Condition Register changes from 1 to 0 .
“
STATus:EESE 1
” is a command used only to reflect
the status of bit 0 of the extended event register in the
status byte.
“ STATus:EESR? ” is used to clear the extended event
register.
The “ *SRE 8 ” command is used to generate a service
request caused solely by the extended event register.
“ :NUMeric[:NORMal]:VALue? ” will not be executed
until a service request is generated.
Using the COMMunicate:WAIT command
The “
COMMunicate:WAIT
” command halts
communications until a specific event is generated.
Example
:STATus:FILTer1 FALL;:STATus:
EESR?\<PMT>
(Read the response to
:STATus:EESR?
)
Loop
COMMunicate:WAIT 1\<PMT>
:NUMeric[:NORMal]:VALue?\<PMT>
(Read the response to
:NUMeric[:NORMal]:
VALue? )
:STATus:EESR?\<PMT>
(Read the response to :STATus:EESR? )
(Return to
LOOP
)
For a description of “
STATus:FILTer1 FALL
” and
“ STATus:EESR? ”, refer to “Using the extended event
register” on this page.
“ COMMunicate:WAIT 1 ” means that communications
is halted until bit 0 of the extended event register is set
to “ 1 ”.
The “
:NUMeric[:NORMal]:VALue?
” command will
not be executed until bit 0 of the extended event
register is set to “
1
”.
