Programming
Addressing and Initializing the Instrument
in the single measurement acquisition mode. This is automatically accomplished
when the *RST common command is used. The *RST command initializes the
instrument to a preset state:
CLEAR 720
OUTPUT 720;”*RST”
Notice in the example above, that the commands are sent to an instrument address of
720. This indicates address 20 on an interface with select code 7. Pressing the green
Preset key does not change the GPIB address.
Set single acquisition mode
An advantage of using the *RST command is that it sets the Keysight 86120B into
the single measurement acquisition mode. Because the READ and MEASure data
queries expect this mode, their proper operation is ensured.
Establish the wavelength range
At the start of each program, be sure to establish the input wavelength range using
the Keysight 86120B’s :CALCulate2:WLIMit command. Setting this command to
off enables the full wavelength range of the instrument. If you are measuring signals
over a narrow wavelength range, use this command to ensure that spurious second
harmonic peaks are not identified.
Refer to “WLIMit[:STATe]” on page 166 ,
“WLIMit:STARt[:WAVelength]” on page 169 , and “WLIMit:STOP[:WAVelength]”
on page 172 . Refer also to “To limit the wavelength range” on page 45 .
