4.5.1
Conventions and General Information
The following sections describe the most important conventions and general informa-
tion concerning the command reference.
4.5.1.1
MEAS<i>
MEAS<i> is used as abbreviation of "MEASurement<instance>". For better readability,
only the abbreviated form (which is also accepted by the instrument) is given in the
command reference.
The <instance> is relevant for instruments supporting several instances of the same
measurement application. It can be omitted if the instrument supports only one
instance, or to address the first instance.
4.5.1.2
FETCh, READ and CALCulate Commands
All commands are used to retrieve measurement results:
●
FETCh...
returns the results of the measurement cycle after the cycle is com-
plete. Before sending a
FETCh...
, start the measurement via an
INITiate...
.
●
READ...
starts a new single-shot measurement and returns the results.
●
CALCulate...
returns one limit check result per
FETCh
result:
–
OK
: The
FETCh
result is located within the limits or no limit has been defined/
enabled for this result.
–
ULEU
("User limit exceeded upper"): An upper limit is violated. The
FETCh
result is located above the limit.
–
ULEL
("User limit exceeded lower"): A lower limit is violated. The
FETCh
result
is located below the limit.
4.5.1.3
Current and Statistical Results
The measurement is repeated according to the selected statistic count and repetition
mode. Consecutive measurement values are stored and used to calculate statistical
results.
Commands for result query often contain a mnemonic that indicates which results are
returned:
CURRent
,
AVERage
,
EXTReme
,
MINimum
,
MAXimum
or
SDEViation
.
