Signal Generator Overview
Rear Panel
11. EVENT 1
This female BNC connector (E8267C only) is used with an internal baseband generator (Option 002/602);
on signal generators without Option 002/602, this female BNC connector is non-functional.
In real-time mode, the EVENT 1 connector outputs a pattern or frame synchronization pulse for triggering
or gating external equipment. It may be set to start at the beginning of a pattern, frame, or timeslot and is
adjustable to within ± one timeslot with one bit resolution.
In arbitrary waveform mode, the EVENT 1 connector outputs a timing signal generated by Marker 1.
A marker (3.3V CMOS high when positive polarity is selected; 3.3V CMOS low when negative polarity is
selected) is output on the EVENT 1 connector whenever a Marker 1 is turned on in the waveform. The
damage levels for this connector are > +8V and <
−
4V.
12. EVENT 2
This female BNC connector (E8267C only) is used with an internal baseband generator (Option 002/602);
on signal generators without Option 002/602, this female BNC connector is non-functional. In real-time
mode, the EVENT 2 connector outputs a data enable signal for gating external equipment. This is applicable
when external data is clocked into internally generated timeslots.
Data is enabled when the signal is low. In arbitrary waveform mode, the EVENT 2 connector outputs a
timing signal generated by Marker 2. A marker (3.3V CMOS high when positive polarity is selected; 3.3V
CMOS low when negative polarity is selected) is output on the EVENT 2 connector whenever a Marker 2 is
turned on in the waveform. The damage levels for this connector are > +8V and <
−
4V.
13. PATTERN TRIG IN
This female BNC connector (E8267C only) is used with an internal baseband generator (Option 002/602);
on signal generators without Option 002/602, this female BNC connector is non-functional. This connector
accepts a signal that triggers an internal pattern or frame generator to start single pattern output. Minimum
pulse width is 100 ns. Damage levels are > +5.5 and <
−
0.5V.
14. BURST GATE IN
This female BNC connector (E8267C only) is used with an internal baseband generator (Option 002/602);
on signal generators without Option 002/602, this female BNC connector is non-functional. This connector
accepts a signal for gating burst power. Burst gating is used when you are externally supplying data and
clock information.
The input signal must be synchronized with the external data input that will be output during the burst. The
burst power envelope and modulated data are internally delayed and re-synchronized. The input signal must
be CMOS high for normal burst RF power or CW RF output power and CMOS low for RF off. Damage
levels are > +5.5 and <
−
0.5V.
