Hi,
when I inject a signal with a power level of 0dBm, MCS display -6dBm! whatever RBW , is that means that the Spectran protects itself at 0dBm while the input level authorized is 10dBm.

No, you seem to use the wrong attenuation. Anway DONT play around with such high levels, it might easily distroy the input!

Hi, i am not using any external or internal attenuator, in my code i parametered this factor using your API codeslike this :
------------------------------------------------------------------------
Attenuation factor
-10=AUTO
0=OFF
and Range 1 to 30 dBm. The Value is positive and is 'subtracted'.
-------------------------------------------------------------------------
i have the measurement errors with MCS (5dB to 6dB) i thik that i need a calibration file to have the good values,
what do you think?

If you are writing your own software you MUST set the attenuator right e.g. 30dB on such high levels.
