FAQ 2003-01-08

If I upgrade my 8614xB optical spectrum analyzer, can I go back?
It is possible to revert to an earlier firmware revision.

FAQ 2003-01-07

Is it possible to make measurements below 600 nm with the OSA?
These measurements are difficult due to the response of the photo detector.

FAQ 2002-12-02

Does the 60 dB attenuation range of the 8156A include the insertion loss of the instrument?
No. The 60dB excludes the insertion loss which is 2.5 to 4.5dB depending upon option.

FAQ 2002-12-02
