Internai Trigger Source
An
internaI trigger source is provided with the following specifications:
Range: 200 ns to 1000 seconds.
Resolution: 100 ns limited by 6 digits.
Accuracy: ±30 ppm.
Trigger Jitter
During Standard Waveforms: < 20 ns.
During User Defined Waveforms:
<
40
ns.
A.2.13 Sweep
The Mode1 395 provides sweep capability for standard and arbitrary waveforms.
If
sweep is selected for an arbitrary waveform, it will
he
expanded or condensed to fit into
exactly 4096 points (only while sweeping; data is not lost). The internal sample rate
clock
if;
set to
50
MHz
and the sweep is performed using DDS techniques.
Additionally a 20 MHz brickwall filter is automatically selected. Attempting to sweep
arbitrary waveforms with spectral contentbeyond 20 MHz will result in distortion
of
the
waveform. Also, position and sync markers may not fonction normally when sweeping
athigher frequencies. This frequency is dependent upon the original size
of
the arbitrary
waveform and is computed as: (50 MHz-;-size).

A.2.14 Amplitude Modulation
The
Model 395 provides external amplitude modulation capability
for
standard and
arbitrary waveforms. Amplitude modulation is selectable as Normal
or
Suppressed
Carrier.
Normal AM
Ota
100% modulation. Amplitude is reduced to one half
of
the programmed value (50%)
with no signal present at the
AM
Input. +L25V at the
AM
Input will resu1t
in
100% of
programmed amplitude,
-L25V
will result in 0%.
Suppressed Carrier Modulation (SCM)
±loo%
modulation. With no signal present
at
the
AM
Input the output amplitude will
be
0 Vp-p. +2.5 V will result in 100%
of
the programmed amplitude. -2.5 V will result
in
minus 100% (full amplitude, but 180 degrees out
of
phase).
