The Maximum 
Output Voltage 
of the NI 5412 is 
determined by 
the Amplitude 
Range and the 
Offset Range.

Output Enable

Software-selectable. When the Output Path is disabled, the 
CH 0 Output is terminated to ground with a 1 W resistor 
equal to the selected output impedance.

Maximum 
Output 
Overload

The CH 0 output can be connected to a 50 

Ω, ±12 V source 

without sustaining any damage. No damage occurs if the 
CH 0 output is shorted to ground indefinitely.

Waveform 
Summing

The CH 0 output supports waveform summing among 
similar paths—specifically, the outputs of multiple NI 5412 
signal generators can be connected directly together.
