@®NEW MEASUREMENT FOR FM.
Input signal fevel under the provision of IHFM-T200, a new meas-
urement method is indicated by available power ratio “dBf’’. To
obtain approximate available power ratio “dBf”’, abstract 0.8 from
attenuater indication of general FMSG (open load indication type);
however, the former measurement, IHFM-T-100 is designated to-
gether too.
The way of modulation on IHFM-T-200 is shown below.

@ The relation between the standard input 65 dBf of IHFM-T-200
and the former indication “dB” is shown below.
