a. Balanced signals are signals present in two separate conductors that are symmetrical relative
to ground, and are opposite in polarity (180 degrees out of phase).
BB TRIG 1 & BB TRIG 2
Connector female BNC
Signal Reserved for arbitrary and real-time baseband generators I/O, such as markers or trigger inputs.

EVENT 1

Connector female BNC Impedance: nominally 50 Ω
Signal A pulse that can be used to trigger the start of a data pattern, frame, or timeslot.
Adjustable to ± one timeslot; resolution = one bit
Markers
Each Arb–based waveform point has a marker on/off condition associated with it.
Marker 1 level = +3.3 V CMOS high (positive polarity selected); –3.3 V CMOS low (negative
polarity selected).
Output on this connector occurs whenever Marker 1 is on in an Arb–based waveform (see
"Using Waveform Markers" on page 223
Damage Levels < −4 and > +8 V
