9.4 Signal Sources
The signal sources that can be selected are internal (INT), external signal input (EXT), internal + external
(ADD), and external synchronization (SYNC).
a) Internal signal source (INT mode, ADD mode)
See “9.1 Output”.
b) External signal input (EXT mode, ADD mode)
Gain setting range:
100 V range: 0.0 times to 220.0 times (initial value: 100.0)
200 V range: 0.0 times to 440.0 times (initial value: 200.0)
Gain setting resolution:
0.1 times
Gain accuracy:
5% (DC, or 45 Hz to 65 Hz, gain is at initial value, with rated
voltage output, no load)
Output phase to input:
In-phase
Input terminal:
BNC connector (rear panel)
(also used as the external sync signal input terminal)
Input impedance:
10 kΩ
Input voltage range:
2.2 V to +2.2 V
Nondestructive maximum
input voltage:
10 V
Frequency range:
DC to 550 Hz (sine wave)
DC to 100 Hz (other than sine wave)
c) External synchronization (SYNC mode)
Synchronization signal source:
External sync signal or line (select one)
Synchronization frequency range:
40 Hz to 500 Hz
Input terminal:
BNC connector (rear panel)
(also used as the external signal input terminal)
Note: External sync signal is not required when line
synchronization is selected
Input impedance:
10 kΩ
Input voltage threshold value:
TTL
Minimum pulse width:
3 ms
Nondestructive maximum
input voltage:
10 V
