Acquisition Length
Select the number of samples to be captured by the transient recorder. The sample
memory sizes 512, 1024 and 2048 MSamples are available.
Decimation Factor
Selects a certain sample to be recorded, i.e. only the n
th
sample is recorded.
Trigger Mode
Select the mode for triggering.
"Continuous" Recording is automatically initiated and continues until the process is
stopped manually. Recording is retriggered every 250ms.
Note: Deactivate the recorder while switching off status.
"Single" Records one signal flow until acquisition length is reached. Initiate a
single trigger event by pressing the "Start Recording" button.
Start Recording
Manually initiate a trigger event to start recording the signal once.
Note: This button applies to "Single Trigger" mode.
Trigger Source
Sets the time for starting the recording. A trigger event can be initiated by the software
itself or by hardware events.
Note: The control signals GP_0 ... GP_5 are part of the I/Q signal and transmitted via
the digital I/Q interface of the R&S instrument.
"Software" R&S DigIConf initiates the trigger event for recording. Recording starts
automatically either within specified intervals, in continuous mode or by
defined user events in single mode.
"Data valid" The external control signal Data Valid initiates the recording of data.
"GP_0" The "(Marker 0)" determines the beginning of recording.
"GP_1 " (Reserve 0) triggers the recording.
"GP_2 " (Trigger 0) triggers the recording.
"GP_3 " (Trigger 1) triggers the recording.
"GP_4 " (Marker 1) triggers the recording.
"GP_5 " (Reserve 1) triggers the recording.
Trigger Type
Set the polarity of the signal to trigger data recording.
Note: "Trigger type" supports all hardware trigger sources like DATA VALID and
GP_0..5. Trigger source "Software" does not use this parameter.
"Rising Edge" The positive slope of the reference signal starts recording the I/Q data
signal.
"Falling Edge" The negative slope of the reference signal triggers recording.
"Low Level"
The low reference level of the signal triggers recording. Low level rep-
resents the logical 0.
