:CALCulate:MARKer:FUNCtion:DELTa:XY
Function
This command displays the delta marker and sets its wavelength or
frequency.
This command queries the difference in wavelength and level between
delta marker and trace marker.
When the level scale is displayed in units of percentage (%), the delta
marker cannot be set or queried.
Syntax
CALCulate:MARKer:FUNCtion:DELTa:XY
<numeric>[{<unit_m>|<unit_h>}]
CALCulate:MARKer:FUNCtion:DELTa:XY?
<numeric>: Wavelength or Frequency
Range From the start wavelength/frequency to the stop
wavelength/frequency
Resolution 0.1 pm when the wavelength marker is displayed
0.01 GHz when the frequency marker is displayed
If a suffix is omitted, the unit will be m or Hz.
If there is no data at the specified wavelength/frequency point, the delta
marker is displayed at the closest data point to the specified
wavelength/frequency.
Response Data
<numeric>,<numeric>
No.
Parameter type
Description
1
<numeric>
Wavelength difference (m) or frequency
difference (Hz) between delta marker and
trace marker
2
<numeric>
Level difference between delta marker and
trace marker
(Unit: dB or no unit (for linear scale
display))
Example of Use
