Remark:
[1] In atypical condition, the specification may have minor differences.
[2] In normal temperature, short circuit in less than half hour will be tolerable.
 CH1 is provided with Overvoltage function. When the output terminal is connected to an external circuit, the
relationships between the output voltage “Vout” of generator and the voltage “Vin” possibly generated by external
circuit are:
If Vout≤1V
DC
, the protective range of Vin is ±3V
If Vout>1V
DC
, the protective range of Vin is ±12.5V
Thereinto, Vout=Amplitude/2+|Offset|, the Amplitude and Offset are the parameters of the signal outputted
from generator.
The generator will cut off the output automatically when Vin exceeds the specified range.
 The voltage inputted to the output connector of CH2 should be within ±3V.
[3] External input voltage should be within ±5V, or else the generator may be damaged.
