Diagrammatic Overview of Measurement Control
As pointed out in the previous sections the commands used to configure and control the measure-
ments, to query the status of the measurement, and to retrieve the measurement results are closely
linked to the settings for the repetition mode and stop condition. The various scenarios are most easily
explained by means of a graphical representation of the measurements.
Single Shot Measurements
Stop condition: NONE
1000
INITiate
RDY
RUN
SAMPle?
FETCh?
A single shot measurement comprising 1000
evaluation periods with stop condition none is per-
formed. The measurement is started with the INI-
Tiate command. The results can be queried us-
ing the SAMPle...? (status RUN or RDY) or
FETCh...? (status RDY) commands. The meas-
urement is configured via:
CONFigure:<meas_obj>:CONTrol <type>,1000
CONFigure:<meas_obj>:CONTrol:REPetition
SINGleshot,NONE,<Stepmode>
The <Stepmode> parameter has no effect.
Stop condition: SONerror
456
INITiate
RDY
RUN
FETCh?
A single shot measurement comprising 1000
evaluation periods with stop condition SONerror is
performed. The measurement is started with the
INITiate command and stopped before the end
of the statistics cycle. The results can be queried
using the SAMPle...? (status RUN or STOP) or
FETCh (status STOP) commands. The number of
bursts measured can be queried using the
FETCh:
<meas_obj>:STATus? command. The
measurement is configured via:
CONFigure:<meas_obj>:CONTrol <type>,1000
CONFigure:<meas_obj>:CONTrol:REPetition
SINGleshot,SONerror
<Stepmode>
The <Stepmode> parameter has no effect.
