SMOothed
flattens the slew rate, resulting in longer rise/fall times.
FAST
enables fast transitions with shortest rise and fall times.
*RST: FAST
Example: See Example "Perform pulse modulation" on page 581.
Manual operation: See "Transition Type" on page 86
[:SOURce<hw>]:PULM:POLarity <Polarity>
Sets the polarity of the externally applied modulation signal.
Parameters:
<Polarity> NORMal | INVerted
NORMal
Suppresses the RF signal during the pulse pause.
INVerted
Suppresses the RF signal during the pulse.
*RST: NORMal
Example: See Example "Perform pulse modulation" on page 581.
Manual operation: See "Polarity" on page 112
[:SOURce<hw>]:PULM:IMPedance <Impedance>
Sets the impedance for the external pulse trigger and pulse modulation input.
Parameters:
<Impedance> G50 | G10K
*RST: G10K
Example: See Example "Perform pulse modulation" on page 581.
Manual operation: See "Impedance" on page 112
[:SOURce<hw>]:PULM:THReshold <Threshold>
Sets the threshold for the input signal at the [Pulse Ext] connector.
Parameters:
<Threshold> float
Range: 0 to 2
Increment: 0.1
*RST: 1
Default unit: V
Example:
SOURce:PULM:THReshold 1
