FETCh[1]|2|3|4 Queries

The FETCh? query sets the measurement type of the specified window/
measurement to either a single, difference, or ratio measurement, with relative
mode either off or on. It then recalculates the measurement and places the result
on the bus. The result format is set by FORM[:READ][:DATA]. Refer to
"FORMat Subsystem"
also be used to retrieve voltage measurement results of V
V
COMP0
The query returns a measurement result when it is valid. The measurement result
is invalid under the following conditions:
– When *RST is executed.
– Whenever a measurement is initiated.
– When any SENSe parameter, such as frequency, is changed.
If data is invalid, the FETCh? query is not completed until all data becomes valid.
The exceptions to this are, if the N432A is in the idle state and the data is invalid,
or the N432A has been reconfigured as defined above and no new measurement
has been initiated. In such cases, the FETCh? routine generates the error
–230,"Data corrupt or stale" and no result is returned. A common cause for this
error is receiving a FETCh? after an *RST. If the expected value and resolution
parameters are not the same as those that were used to collect the data, error
–221,"Settings conflict" occurs.
