Hi, we use keysight N7700A IL/PDL software to measure the WDM IL and PLD spectrum.
The software will output 2 spectrum curve : TE and TM after sweep.
Is there any naming rule for TE/TM curve?
When we measure repeatedly, the same curve sometimes named different name.
it outputs two curves, A named TE, B named TM
but sometimes A named TM, B named TE
this makes us a little confuse.
