DC superimposing function
By setting the DC BIAS, the DC component may be operated in constant current mode or in
constant voltage mode.
Remote sensing function of return current
With the remote sensing function, leak current can be ignored and the load current is correctly
ignored. However, the maximum average current is up to
± 10 mA.
