Limit Tests
8-7
SCPI programming
A) FEED <name>
Name parameters:
•
CALCulate1 — Limit tests will be performed on the result of a math calculation
(mX+b, m/x+b, or log).
•
SENSe — Limit tests will be performed on the input signal. Note however, that Rel can
be used on the result of a math calculation as well as the input signal. Limit tests will be
performed on the result of the Rel operation (see CALCulate2:NULL). Details on rela-
tive, mX+b, m/X+b, and log are provided in
.

CALCulate2 Subsystem:
Select input path for limit testing; CALCulate[1]
or SENSe[1].
Limit 1 Testing:
Configure upper limit:
Set limit; -9.99999e20 to 9.99999e20.
Configure lower limit:
Set limit; -9.99999e20 to 9.99999e20.
Enable or disable Limit 1 test.
Return result of Limit 1 test; 0 (pass) or 1(fail).
Limit 2 Testing:
Configure upper limit:
Set limit; -9.99999e20 to 9.99999e20.
Configure lower limit:
Set limit; -9.99999e20 to 9.99999e20.
Enable or disable Limit 2 test.
Return result of Limit 2 test; 0 (pass) or 1(fail).
Configure and control Rel:
Specify Rel value; -9.999999e20 to 9.999999e20.
Enable or disable Rel.
Return CALC2 reading(s) triggered by INITiate.
Return last (latest) CALC2 reading.
