4.9 Amplification of External Signal
The EC1000SA can be used as an amplifier to which a signal is input from the external signal input
terminals on the rear panel, by selecting the external signal source mode (AC-EXT or AC+DC-EXT).
Connect the external signal source to the external signal input/external sync signal input terminal (EXT
SIG IN/EXT SYNC IN) on the rear panel. For this connection, use a coaxial cable with a BNC connector.
The input impedance is 10 k
Ω
(unbalanced) and the input frequency ranges from DC to 550 Hz.
Output voltage = input voltage × external input gain
