Connector
Use
RF OUT
Output for the upconverted signal at the requested RF frequency.
PLS MOD Input for the 3.3 V TTL for pulse-modulating the RF signal.
LO IN
Connects to the RF OUT connector on the NI 5650/5651/5652 front panel.
This connector routes the local oscillator from the NI 5650/5651/5652 to the
NI 5611.
LO OUT

This connector routes the baseband input from the NI 5450/5451 AWG module.
I-
Connects to the CH 0-/I- connector on the NI 5450/5451 front panel.
This connector routes the baseband input from the NI 5450/5451 module.
Q+
Connects to the CH 1+/Q+ connector on the NI 5450/5451 front panel.
This connector routes the baseband input from the NI 5450/5451 AWG module.
Q-
