The CLK IN SMA connector accepts an external clock that can be used as
a Reference clock, a Sample clock, or a Sample clock timebase.
The CLK OUT SMA connector provides a clock signal that can be shared
by other devices.
The PFI 0 and PFI 1 SMB connectors are bidirectional connections that can
accept a trigger from an external source and can start or step through
waveform generation or route signals from several clock, event, and trigger
sources.
The CH 0+/I+ SMA connector provides differential waveform output for
channel 0.
The CH 0
−
/I
−

channel 1.
The CH 1
−
/Q
−
SMA connector provides complementary differential
waveform output for channel 0.
