separately.
Controlling multi evaluation measurements
A multi evaluation measurement is controlled like any other measurement; see Mea-
surement Control. The following commands start, stop and abort a multi evaluation mea-
surement within a particular firmware application (<FWA>):
INITiate:<FWA>:MEValuation
STOP:<FWA>:MEValuation
ABORt:<FWA>:MEValuation
The following commands query the measurement state and the substates:
FETCh:<FWA>:MEValuation:STATe?
FETCh:<FWA>:MEValuation:STATe:ALL?
Example: INITiate:WIMax:MEASurement<i>:MEValuation
Retrieving measurement results
The commands for retrieving the results of a multi evaluation measurement follow general
syntax rules (see Retrieving Measurement Results). In general it is possible to specify
the subset of results needed using an additional <View> mnemonic:
READ:<FWA>:MEValuation:<View>:<Statistics>...?
FETCh:<FWA>:MEValuation:<View>:<Statistics>...?
The result subsets are closely related to the different views that the multi evaluation
measurement provides in manual control.
Example: READ:WIMax:MEASurement<i>:MEValuation:EVM:DATA:AVERage?
Retrieving results for disabled views
In some measurements it is possible to disable individual views and results in order to
gain measurement speed. The READ...? and FETCh...? queries act differently on
disabled views:
●
A FETCh...? command leaves the view in the unchanged (disabled) state and
returns NCAP (not captured) results. The view must be enabled explicitly to obtain
valid results.
●
A READ...? command enables the view implicitly and returns valid results. After
program execution, the view returns to the disabled state.
5.4.3 Signaling Generator Control
The commands used to control the RF generators of the different signaling applications
are analogous to the generator control commands explained in section chapter 5.4.1,
