  • Page 324: Trigger:source

    TRIGger:SOURce TRIGger:SOURce Syntax TRIGger:SOURce {IMMediate|BUS} This command selects the trigger source for measurements. The U3606A will accept a software (bus) command or an immediate (continuous) trigger. The valid options are: • IMMediate: For the IMMediate (continuous) source, the trigger signal is always present.
  • Page 325 • The instrument selects the IMMediate trigger source after a Factory Reset (*RST command) or an Instrument Preset (SYSTem:PRESet command). • If the selected trigger source is invalid due to a settings conflict, the source reverts automatically to IMMediate. A settings conflict error message is also generated. U3606A Programmer’s Reference...

  • Page 328: Abort

    • The Factory Reset (*RST) and Instrument Preset (SYSTem:PRESet) command will abort a measurement and set all measurement parameters to their factory settings.

  • Page 341: Rcl

    This *RCL (ReCaLl) command recalls the instrument state stored in the specified storage location. If you recall the instrument state from a storage location that is empty, the U3606A always sets to the factory default settings. When shipped from the factory, storage locations 1 through 16 are empty.

  • Page 342: Rst

    Syntax *RST The *RST (ReSeT) command resets the instrument to its factory default state, which is the state when the U3606A is powered- on for the first time. Remarks • The *RST command does not clear the event registers and the error queue.
