Message Details
:CALCulate:MARKer[1|2|3|4]:FUNCtion:DELTa:X:OFFSet[:WAVelength]
Function
This command displays the delta marker and sets its wavelength.
This command queries the wavelength difference between delta marker
and trace marker.
Syntax
:CALCulate:MARKer[1|2|3|4]:FUNCtion:DELTa:X:OFFSet[:WAVe
length] <numeric>[{<unit_m>|<unit_h>}]
:CALCulate:MARKer[1|2|3|4]:FUNCtion:DELTa:X:OFFSet[:WAVe
length]?
The process will not change regardless of whether a number [1|2|3|4] is
specified or omitted.
<numeric>: Wavelength or frequency of delta marker (m|Hz)
Range From the start wavelength to the stop wavelength
Resolution 0.1 pm
If a suffix is omitted, the unit will be m.
If there is no data at the specified wavelength point, the delta marker is
displayed at the closest data point to the specified wavelength.
If [:WAVelength] is omitted when setting the frequency of the marker
display, the delta marker can be set even by the frequency.
Range From the start frequency to the stop frequency
Resolution 0.01 GHz
If a suffix is omitted, the unit will be Hz.
Response Data
<numeric>
<numeric>: Wavelength difference or Frequency difference (m|Hz)
If [:WAVelength] is omitted when setting the frequency of the marker
display, the frequency difference of the delta marker can be obtained.
