NI PXI-5404
SINE Out
The SINE out provides the sine wave output. The maximum output levels on this connector depend on the type of load termination. If the output of the NI PXI-5404 terminates into a 50 Ω load, the output levels are adjustable to a maximum of ±1 V, as shown in the following figure.
If the output of the NI PXI-5404 terminates into a high-impedance load (HiZ), the output levels are adjustable to a maximum ±2 V. If the output terminates into any other load, the levels are as follows:
Vout = ± [ RL / (RL +RO) ] × 2 V
where
Vout is the maximum output voltage level.
RL is the load impedance in ohms.
RO is the output impedance on the NI PXI-5404 and is equal to 50 Ω.
