[:SOURce<hw>]:CHIRp:BANDwidth <Bandwidth>
Sets the modulation bandwidth of the chirp modulated signal.
Parameters:
<Bandwidth> float
Range: 0 to Depends on hardware variant
Increment: 0.01
*RST: 1E3
Example: See Example "Perform chirp modulation" on page 569.
Manual operation: See "Bandwidth" on page 96
[:SOURce<hw>]:CHIRp:COMPression:RATio?
Queries the pulse compression ratio (= product of pulse width (s) and bandwidth (Hz)).
Return values:
<Ratio> float
Range: 0 to 80E6
Increment: 0.01
Example: See Example "Perform chirp modulation" on page 569.
Usage: Query only
Manual operation: See "Compression Ratio" on page 97
[:SOURce<hw>]:CHIRp:DIRection <Direction>
Selects the direction of the chirp modulation.
Parameters:
<Direction> DOWN | UP
*RST: UP
Example: See Example "Perform chirp modulation" on page 569.
Manual operation: See "Direction" on page 95
[:SOURce<hw>]:CHIRp:PULSe:PERiod <Period>
Sets the period of the generated modulation chirp. The period determines the repetition
frequency of the internal signal.
