:CLIMits:FAIL?
:CALCulate3:CLIMits:FAIL?
Read composite result of limit tests
Description
This query command is used to obtain the composite result of the LIMIT 1 and LIMIT 2 tests.
The composite result is the logical OR'ed summary of LIMIT 1 and LIMIT 2:
1 = One or both tests have failed.
0 = Both tests have passed.
In the event of a failure (1), you can determine which test(s) has failed by using the fail com-
mand of each limit (:LIMit1:FAIL? and :LIMit2:FAIL?).
This command (like the other fail commands) does not clear the fail indication for LIMIT 1 or
LIMIT 2.
:BSTRobe:STATe <b>
:CALCulate3:BSTRobe:STATe <b>
Control binning strobe
Parameters
<b> =
1 or ON
Enable binning strobe
0 or OFF
Disable binning strobe
Query
:STATe?
Query state of binning strobe
Description
This command is used to enable or disable the strobe for the binning operation. When enabled,
digital output line #4 is used for the binning strobe pulse. After the appropriate digital pattern is
placed on the other three lines of the output port, the >10µsec strobe pulse is asserted on line
#4. The strobe is used to "inform" your external binning circuit that the output port (lines 1, 2
and 3) is ready to be read.
:IMMediate
:CALCulate3:IMMediate
Perform CALC 3
Description
When you change the configuration of the limit test, the next reading is evaluated according to
that new test configuration. If the instrument is not in a continuous measurement mode (e.g.,
waiting for a manual trigger), the test will not be performed until the next reading conversion
occurs.
This action command allows you to re-process the current input data to test new limits. For ex-
ample, assume the instrument is in a non-continuous measurement mode and requires a manual
trigger to cause the next reading conversion. Changing the test limits will not affect the last test
result. However, sending the :IMMediate command re-processes the data and evaluates the read-
ing according to the new test limits. Note that sending the :IMMediate command does not ini-
tiate a reading conversion.
