I used 86122 Wavemeter from Keysight to measure the output wavelength for a device.
The connection interface between Wavemeter to PC is via internet.
We used commend ":MEAS:SCAL:POW:FREQ?" to query the frequency then transfer it back to wavelength by mulit factors.
I got very strange result sometimes that the returned wavelength is 100nm.
No error occured during the query process.
Does any one has the same experience?
