CALCulate
-
NULL
measurements (also called
relative
measurements) provide a reading
which is the difference between a stored null value and the input signal.
-
See the section titled “Math Operations” beginning, for more detail on the
CALCulate
operations.
Example
Set the Calculate Math Function to Make Upper and Lower Limit Tests on Each
Measurement
CALC:FUNC LIM
Set calculate function to limit.
CALC:LIM:LOWer
Set the lower limit to test against.
CALC:LIM:UPPer
Set the upper limit to test against.
CALC:STATe ON
Enable the limit math operation.
:FUNCtion?
CALCulate:FUNCtion?
queries the multimeter to determine the present math
function. Returns
AVER
,
DB
,
DBM
,
LIM
, or
NULL
.
Example
Query the Calculate Math Function
CALC:FUNC?
Query the calculate function.
:LIMit:LOWer
CALCulate:LIMit:LOWer <
value
>|MIN|MAX
sets the lower limit for limit testing.
You can set the value to any number between 0 and
120% of the highest range,
for the present function.
MIN
= –120% of the highest range.
MAX
= 120% of the
highest range.
You must turn on the math operation e.g., execute
CALC:STAT ON before writing to the math register
. The lower limit is stored in
volatile memory.
Example
Set the Lower Limit
CALC:STAT ON
Turn on the math operation.
CALC:LIM:LOW 1000
Set the lower limit.
CALC:FUNC LIM
Select the LIMit math operation. You can
select the calculate function at any time before or after enabling the
calculate state.
