5. AUXILIARY I/O

This female 37- pin connector is active only on instruments with an internal baseband generator (Option 601/602); on signal generators without Option 601/602, this connector is non- functional. This connector provides access to the inputs and outputs described in the following figure.

EVENT 3: Used with an internal baseband generator. In arbitrary waveform mode, this pin outputs a timing signal generated by Marker 3. A marker (3.3 V CMOS high for both positive and negative polarity) is output on this pin when a Marker 3 is turned on in the waveform. Reverse damage levels: > +8 V and < −4 V.

EVENT 4: Used with an internal baseband generator. In arbitrary waveform mode, this pin outputs a timing signal generated by Marker 4. A marker (3.3V CMOS high for both positive and negative polarity) is output on this pin when a Marker 4 is turned on in the waveform. Reverse damage levels: > +8 V and < −4 V.

PATT TRIG IN 2: Accepts a signal that triggers an internal pattern or frame generator to start single pattern output. Minimum pulse width: 100 ns. Damage levels: > +5.5 V and < −0.5 V.

ALT PWR IN: Used with an internal baseband generator. This pin accepts a CMOS signal for synchronization of external data and alternate power signal timing. Damage levels are > +8 V and < −4 V.

DATA OUT: Used with an internal baseband generator. This pin outputs data (CMOS) from the internal data generator or the externally supplied signal at data input.

DATA CLK OUT: Used with an internal baseband generator. This pin relays a CMOS bit clock signal for synchronizing serial data.

SYM SYNC OUT: Used with an internal baseband generator. This pin outputs the CMOS symbol clock for symbol synchronization, one data clock period wide.
