Remote command:
[:SOURce<hw>]:CHIRp:BANDwidth on page 570
Trigger Mode
Selects the trigger mode for chirp modulation signals.
To supply the external trigger signal, use the Pulse Ext connector.
"Auto"
Generates the chirp modulation signal continuously.
"Single"
Generates the chirp modulation signal once, triggered internally with
"Execute Single Trigger" on page 97.
"Ext Single"
Generates a single chirp pulse, triggered by an external signal.
"Ext Triggered"
Generates the chirp pulse each time an external trigger event occurs.
"Extern Gated"
Generates the chirp pulse signal triggered by an external gate signal.
Remote command:
[:SOURce<hw>]:CHIRp:TRIGger:MODE on page 571
Pulse Width
Sets the width of the generated pulse. The pulse width must be at least 1 us less than
the set pulse period. Option R&S SMA100B-K23 provides a higher resolution.
For more information, see data sheet.
Remote command:
[:SOURce<hw>]:CHIRp:PULSe:WIDTh on page 571
Compression Ratio
Indicates the pulse compression ratio, i.e. the product of the pulse width in (s) and the
bandwidth (Hz). Pulse compression increases the range resolution and the signal to
noise ratio of pulsed signals.
Remote command:
[:SOURce<hw>]:CHIRp:COMPression:RATio? on page 570
Show Connector
Accesses a dialog that displays the physical location of the selected connector on the
front/rear panel of the instrument.
