Modulation Input Scaling
Signal present at input connector will modulate output signal as defined by selected
modulation mode. Input scaling is defined as follows for each mode:
Mode 1nput Level Scale
Normal AM: +1.25 V ± 100 mV = 100%
-1.25V±100mV=
0%
SeM
+2.50 V ± 200 mV = 100%
-2.50 ± 200 mV = -100%
Modulation Distortion
<1
% at 1 kHz modulation frequency and a depth
of
80%.
Modulation Bandwidth
>100 kHz.
A.2.15 Sync Output
The Model 395 allows the sync output to be selected from among seven sources.
Waveform Sync
For standard waveforms this will
be
an approximate 50% dutYcycle waveform derived
by "zero crossing" the output waveform. Forarbitrary waveforms this will be a pulse
with a minimum width
of
40
fiS. The pulse may be positioned to be coincident with any
point on the arbitrary waveform and is programmed by the sync address parameter.
Position Marker
For arbitrary waveform a marker signal is provided, allowing any point on a waveform
to have an associated marker bit set high or low.
Trigger Signal
This will select the current trigger signal. This is usefui for synchronizing bursted
or
gated signals.
Burst Done
This will select the internaI end
of
burst signal and will be a pulse coincident with the
end
of
the last cycle
of
a burst.
Loop Done
This will select the internal end
of
sequence signal which is a pulse coincident with the
completion
of
a Iink sequence.
Sweep Marker
Selects the frequency sweep marker signal. Foruse with frequency sweeps. A
TIL
high
corresponds to an active marker.
Pen Lift
Selects the sync out as a
pen
lift signal for use with strip chart recorders.
Pen
is lifted
whenever the sweep is idle
or
during the "retrace."
