My intention is to use the P275 for measuring the deviation of the 10.7MHz output of a STL-Receiver on 2.4GHz.

Please note that the device is optimized for FM broadcast (wide FM, bandwidth) so its ability to measure different services out of the FM band may be restricted.

Is it possible to modify the P275 analyzer and feed it with a 10.7MHz modulated FM signal? It would be interesting for measuring signals outside the band 87.5-108 MHz.
Thanks
