ABORt
Description: Terminates any measurement in progress and resets the state of the trigger system. Note
that
ABORt will leave the measurement in a stopped condition, and forces
INITiate:CONTinuous to OFF.
Syntax: ABORt
Argument: None
Valid Modes: Any
4.5.3 FETCh Queries
The FETCh? group of queries is used to return specific measurement data from a measurement cycle that has been
INITiated and is complete or free-running. FETCh? performs the data output portion of the measurement. FETCh?
does not start a new measurement, so a series of FETCh? queries may be used to return more than one set of processed
measurements from a complete set of acquired data. FETCh? usually returns the current value of measurements, and
should be used anytime free running data acquisition is taking place
(INITiate:CONTinuous ON ). If FETCh? is used
for single measurements ( INITiate:CONTinuous OFF) , no data will be returned until a measurement has been INITiated
and is complete.
FETCh:CW:POWer
Description: Returns the current average reading of the specified channel in power units. Channel’s
units setting is forced to power units.
Syntax: FETCh[1|2]:CW:POWer?
Returns: power in <dBm, Watts>
Valid Modes: CW, Modulated and Statistical modes
Special Case: If in ratiometric mode, reading will be in units of dBr (log) or Percent Power (linear).
FETCh:CW:VOLTage
Description: Returns the current average reading of the specified channel in voltage units. Channel’s
units setting is forced to voltage units.
Syntax: FETCh[1|2]:CW:VOLTage?
Returns: voltage in <dBuV, dBmV, dBV, Volts>
Valid Modes: CW, Modulated and Statistical modes
Special Case: If in ratiometric mode, reading will be in units of dBr (log) or Percent Voltage (linear).
FETCh:MARKer:POWer
Description: Returns the current power reading at the specified marker on the specified channel.
Syntax: FETCh[1|2]:MARKer[1|2]:POWer?
Returns: power or voltage in active units
Valid Modes: Pulse and Statistical modes
Restrictions: MARKer:MODe must be set to VERT
