Pulse modulation settings
With the commands described in this section, you can configure the settings for pulse
modulation, select the trigger mode and determine delay times for the pulse modula-
tion signal.
Example: Perform pulse modulation
The example shows a command sequence to perform pulse modulation.
// Reset the instrument to start from an initial state
*RST; *CLS
// Set the RF signal frequency and level
