4.10 Adding External Signals and Internal Signals
When in the EC1000S in 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 k
Ω (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”
.
