Software-selectable. When disabled, CH 0 out is terminated

with a 1 W resistor with a value equal to the selected output

impedance.

Output

Overload

The CH 0 output can be connected to a 50 Ω, ±12 V

(±8 V for the Direct Path) 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 5421

signal generators can be connected together.
