11683A,    E4417A(more),  N1912A(more)
10 dBm,   10.02 dBm,       10.03 dBm
15 dBm,   15.03 dBm,       15.04 dBm
20 dBm,   20.06 dBm,       20.08 dBm

Why the difference?
Specifications are not asked.
Correction data of thermocouple sensor are radically different?

--- Add contents ---
Nominal values of each
11683A,         437B,          E4417A,         N1912A
10.00 mW,   10.00 mW,    10.032 mW,      ?
  31.6 mW,     31.6 mW,   31.785 mW,      ?
100.0 mW,   100.0 mW,    101.35 mW,      ?

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)
