:CALCulate:MARKer:TMK:DATA
Function
This command sets the wavelength or frequency of the trace marker and
displays the trace marker.
This command queries the wavelength or frequency and level of the trace
marker.
When the level scale is displayed in units of percentage (%), the trace
marker cannot be set or queried.
Syntax
:CALCulate:MARKer:TMK:DATA <numeric>[{<unit_m>|<unit_h>}]
:CALCulate:MARKer:TMK:DATA?
<numeric>: Wavelength or Frequency (m|Hz)
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 trace
marker is displayed at the closest data point to the specified
wavelength/frequency.
Response Data
<numeric>,<numeric>
Trace Marker wavelength (m|Hz)
Trace Marker level (dBm|dB|W)
Example of Use
