7.4 Performance test
This section describes a simple performance test of the unit.
7.4.1 Test of constant voltage mode
The gain accuracy and the monitor accuracy when the standard signal input is given in constant voltage
mode are checked.
Give voltage input from the reference DC power supply to the external DC bias signal input. Make sure
that the output is +10 kV for +10V input.
Make sure that the error between the actual output and the value of the output monitor is 0.3% or less.
