Trigger Output
The Trigger
is an output when the selected trigger source is internal. This
port provides a squarewave (OV and - 3V) from a 1 source impedance whose
edges are related to the internal trigger interval generator. The Trigger port is pro-
tected from externally applied voltages up to
±
1 5 V
.
X Axis/Phase Output
When sweeps are active, this output produces a voltage ramp from
to
+
5V
whose voltage is proportional to the sweep frequency.
When sweeps are not active, this output produces a voltage from -3
.2V
to
+
5V
that is proportional to the magnitude of the Start/Stop Phase or -5V to
+
5V that
is proportional to the Phase offset during phase locked loop operation.
X3 Output (Option 001)
The X3 output amplitude and DC offset equal three times the displayed values if the
Main output is terminated into
and the X3 output into more than 5000. This out
-
put cannot source more than 30mA peak or
±
15V peak. This means the waveform
clip if you add any DC offset to a 30Vp-p signal.
