OPERATING MODES
Continuous (
free -
running
)
Output
The
following
procedure will
provide
continuous
output
from the FG
5010 .
1. Select the
desired
waveform
and
press the CONT
button .
2. Press FREQ and , via the keyboard , enter the desired
frequency .
3. Press AMPL and , via the keyboard , enter the
waveform
amplitude .
4. Connect the load to the FG 5010 OUTPUT connector
using suitable cable , attenuators terminators , etc.
5. Press the OUTPUT ON button .
When operating in the continuous mode , the output
waveform and any applicable parameter can be changed at
any time . To monitor the value of a given parameter , simply
press the appropriate button ; the value will be displayed
with
no
affect on the
output
.
The HOLD function can be activated in this mode when
the frequency of the output waveform is 200 Hz or less . The
output will be held at its level until the HOLD button is
pressed
again .
Triggered , Gated , and Burst Output
These modes require application of an external trigger
signal or manipulation of the manual trigger button . The out
put can also be triggered remotely over the GPIB ; refer to
the
Programming
Section for
details
.
NOTE
Frequency
accuracy is
degraded
in
these modes ( see
specifications ) . Frequency accuracy can be improved
( 0.1 % ) by setting up for CONT operation then
switching to
one of the
triggered
modes .

Operating Instructions - FG 5010
The trigger input impedance and trigger threshold level
are
selectable . The FG
5010 is
shipped
from
the
factory with
the trigger input impedance set at 1 M , which can be
changed to 50 . The trigger threshold level is set at 0.5 V
and can be
changed
to
volts . These
parameters
are
changed by relocating internal jumpers .
WARNING
Refer qualified service personnel to the Maintenance
section
of
this
manual for
jumper
locations .
When operating in these modes , the TRIG'D light func
tions as a trigger level indicator . With + SLOPE selected ,
when the input signal is above the threshold level the
TRIG'D light will
be
continuously on . When the
input signal
is below the
threshold level , the
TRIG'D
light is
continuously
off . A flashing light means the input signal is transitioning
the threshold and toggling the input . When -SLOPE is se
lected , the TRIG'D light functions as for + SLOPE but the
polarities are
reversed
.
It
should
be
noted that
the
generator can be
triggered
manually only on + SLOPE when operating in these modes .
Triggered
Output
In this mode , one cycle of the selected waveform is gen
erated for each trigger signal at the TRIG / GATE IN connec
tor . Set up is as described under Continuous Output . Unless
the SLOPE button is extinguished to select - SLOPE , +
SLOPE will be assumed .
Gated
Output
In this mode ,
the
selected
waveform
is
generated
con
tinuously for the duration of the gating pulse applied to the
TRIG / GATE IN
connector
. If
triggered
manually
, output
will
be continuous until the MAN button is released . As in trig
gered mode , + SLOPE will be assumed unless the SLOPE
button
is
extinguished to select
-
SLOPE .
Burst
Output
In this mode , a pre - determined number of cycles of the
selected waveform is generated each time the generator is
triggered . The number of cycles per burst is selectable via
the keyboard from 1 to 9999. The first pulse edge to pass
through the threshold level will trigger the generator . All sub
sequent pulses will be ignored until the selected burst is
complete . The next pulse after the burst is complete will
2-9
