20 dBm, 20.06 dBm, 20.08 dBm
Why the difference?
Specifications are not asked.
Correction data of thermocouple sensor are radically different?

As far as I know is due to non-linearity compensation of thermocouple sensor.(437B ≠ E4417A)
Because of this, 3% in the 10 dBm to 20 dBm range 8481A specs.
I want to know is Nominal Value of N1912A range.(thermocouple mode)

The N1912 has a basic accuracy of +/- .8% or +/- .04 dB. The stand alone 11683A is not accurate to test these models. You need an option H01 version which uses an external DC voltage standard which will test the power meters correctly.
