TRIG
OUTPUT
One
trigger
pulse is
generated at
this
connector
for
each cycle of the output waveform . The trigger out
put
remains
positive
during
the off time
of the
TRIG
, GATE
, and
BURST
modes
.

OUTPUT
This connector is the main output for all waveforms
generated
by the
FG
5010 .
Output
Connections
The output of the FG 5010 is designed to operate as a
50 voltage source working into a 50 load . At higher fre
quencies , an unterminated or improperly terminated output
will cause aberrations on the output waveform . Loads less
than
50
will
reduce the
waveform
amplitude .
Excessive
distortion
or
aberrations , due to
improper
ter
mination , are less noticeable at the lower frequencies ( espe
cially with sine and square waveforms ) . To ensure wave
form purity , observe the following precautions .
OPERATING CONSIDERATIONS
1. Use good quality 50 2 coaxial cable and connectors .
2. Make all
connections tight and
as short as
possible
.
3. Use
good
quality
attenuators if it is
necessary
to
re
duce waveform amplitude applied to sensitive circuits .

4. Use
terminations
or
impedance
-
matching
devices
to
avoid
reflections
when using long
cables ( six feet
or more ) .
5. Ensure that attenuators , terminations , etc. have ade
quate power handling capabilities for the output waveform .
If there is a
dc
voltage
across
the
output load ,
use a
coupling capacitor in series with the load . The time constant
of the
coupling capacitor and load
must be
long
enough to
maintain pulse flatness .

When this button
is
illuminated ,
the
output
is
as
defined
by
the
programmed
parameters .
When
the
button is
extinguished ,
gener
ated
signals
are
disconnected
from the connector .
- When this button is illuminated ,
the
output waveform
is
comple
mented . Offset remains the same .
Impedance Matching
If the FG 5010 is driving a high impedance such as the
1 MS input impedance ( paralleled by a stated capacitance )
of the vertical input of an oscilloscope , connect the trans
mission line to a 50 attenuator , 50 2 termination , and then
the oscilloscope input . The attenuator isolates the input ca
pacitance of the device , and the FG 5010 is properly
terminated .
First
Time
Operation
The controls and connectors pages give a description of
the front panel controls . The function and mode selection
controls are outlined in blue . The parameter selection , mem
ory , and output controls are outlined in gray . The trigger
controls
and
input are
outlined
in green .
The following exercise will familiarize the operator with
most functions of the FG 5010 .
NOTE
If any discrepancies are encountered during the exer
cise , refer the condition to qualified service personnel .
Connect the FG 5010 OUTPUT to the vertical input of an
oscilloscope . Use a suitable length of 50 M coaxial cable and
a 50 2 termination . Apply power to the oscilloscope and the
FG 5010 power module .
