5.15.3.4 Stopped measurement
The measurement system only assumes this state when [STOP/CONT ] is pressed
while a measurement is being performed. No currently valid measured values or data
sets are available. Measured values should not be read out via the remote-control sta-
tion when the system is in this state. The Control keys or buttons have the same func-
tion as when a measurement is terminated (see
Chapter 5.15.3.3, "Terminated mea-
surement" , on page 341).
5.16 Start Conditions
The Analyzer Config panel is used to define which conditions trigger the start of a mea-
surement.
The menu item "Start Cond" defines when, how often or under what conditions mea-
sured values are to be recorded.
In addition to continuous operation, the following operating modes for recording mea-
sured values can be selected from this panel:
●
Time-controlled measured value recording
●
Externally controlled measured value recording (i.e. controlled by altering the mea-
surement signal), known for short as "external sweeps"
●
Level-controlled measured value triggering
When the conditions for measured value recording are met, the measured value is trig-
gered, displayed in the measurement results panel and if appropriate stored in a mea-
sured value buffer internal to the device. The measured value list can be displayed
numerically or graphically in one or more "sweep graphs" out of the available total of
four.
In order for the measured value list to be recorded, the measured values of interest
must be selected as traces (Y source) in the "Sweep Graph Config" panels. "X-axis"
("x-Source") should be set to "Sweep". Four sweep graphs with two traces each are
available for measured value recording, so that a maximum of eight measured values
can be recorded simultaneously.
