4.4 Operation example in constant c constant
voltage mode
This section describes operation example of this unit in constant c constant voltage mode.
In this mode, AC signal is constant current and DC signal is constant voltage. This mode is used to run AC
by applying DC bias to capacity load.
In constant current mode, total mode and load mode previously described can be selected.
The frequency at the boundary of the constant voltage operation and the constant current operation varies
depending on the load capacity.
Refer to "3.2.1 Amplifier operation mode, Chapter 3" and "
Figure 5.4 and Figure 5-12, 5.4, Chapter 5".
The TOTAL terminal of OUTPUT Lo is connected to the casing. Therefore, the total mode can be used for
grounded load or load that can be grounded.
In load mode, leak current with stray capacitance and load current are detected from different routes.
Therefore, load mode cannot be used for load which is grounded.
Constant current operation is available for AC signal and constant voltage operation is available for DC
signal. When the signal is ON, unusual voltage output is not given with the output open.
When the output is short-circuited, be careful for DC short-circuit current.
