*1
Measurements are made using the reference optical system during measurement and the radiant power measurement system on
the hologram unit shown in Fig. 2.
*2
It should be noted that the RF signal amplitude in these specifications is denoted by I
RF
, and represents the amplitude of the 11T
signal. As in the case described in
*1
, I
RF
is measured using the measurement system shown in Fig. 2.
