MF-F5M Frequency Extension

This option extends the frequency of 500 kHz MFLI lock-in amplifiers and 500 kHz MFIA impedance analyzers to the frequency range of DC to 5 MHz. The upgrade is enabled on the instrument by a software key and does not require any hardware changes or return of the instrument. Also, the installation can be carried out at any later point in time. The upgrade is independent of the option set installed and does not affect any of the other instrument specifications, only the available frequency range for the oscillators.
