4.10 Adding External Signals and Internal Signals
When in the APS-1102 internal + external mode (AC-ADD, AC+DC-ADD), the internal signal source
signal can be added to the external signal input prior to output.
When using a signal input from an external source as a signal source, connect to the rear panel external
signal input/external sync signal input terminal (EXT SIG IN/EXT SYNC IN).
For this connection, use a coaxial cable with a BNC connector.
The input impedance is 10 kΩ (unbalanced), and the input frequency ranges from DC to 500 Hz.
See “4.9 Amplification of External Signal”.
For description of the External signal input/external sync signal input terminalspecifications:
See “3.3.4 External signal input/external sync signal input terminal”.
The setting ranges for output voltage and output frequency can be limited.
See “3.4.7 Using limiter functions”.
See “5.5.5 Setting range limiter (LIMIT)”.
