FGX-293 is a function generator incorporating ar-
bitrary waveform capability.
It can generate arbitrary waveform with 12bit reso-
lution, max. 500K point length, and max. 50MS/s
sampling rate.
Waveform can be outputted by each mode of con-
tinuous, triggered, gate, or burst with internal or
external reference.
It can match to wide variety of use with combining
various seep functions, AM, FM, and FSK modula-
tion. Owing to editing function for automatic incre-
ment, line draw, defined waveform, etc., easy gen-
eration of arbitrary waveform can be realized.
Also control by PC is possible by standard
equipped RS-232C and GPIB.(SCPI compatible)

Features
Wide range of frequency generation up to
31MHz (for sine and square waveform)
It is possible to generate 10μHz ultra low fre-
quency up to 31MHz high frequency.
DDS (Direct Digital Synthesizer) method
Standard waveform keeps high accuracy for fre-
quency, ±25ppm by using DDS method.
Frequency setting can be made with 10digit or
1μHz high resolution.
Linear/Log Sweep function
Linear/Log sweep is possible for sweep sine,
square, and triangle waveforms.
Duty variable, symmetry variable
Duty ratio for square wave is variable without
changing frequency using duty variable function.
Variable range is 20% to 80% at less than 5MHz,
and 40% to 60% at less than 20MHz.
Symmetry of triangle waveform is variable within
the range of 10% to 90%.
500K point long size memory for arbitrary
waveform
Data length can be set freely within 500K points.
Setting start address and data length for arbitrary
waveform output enables any separation in wave-
form memory. Sampling rate for arbitrary wave-
form is max. 50MS/s (20ns) with analog output.
Interface
GP-IB and RS-232C are equipped as standard.

Standard waveform
3 kinds of waveforms, sine,
square, and triangle can be
obtained. Max. Output is 10Vp-
p(50 Ωtermination), and offset
can be effective until peak volt-
age becomes ±5V (50 Ωter-
mination).
Trigger function
It outputs one cycle for the se-
lected waveform. Manual, inter-
nal signal, or external signal can
be selected as a trigger source.
Burst function
Generation of burst waveform is
possible for all waveforms.
Number of waveforms is from 2
to 99,999. Photo shows two
numbers of triangle, 5 numbers
of sine, and 10 numbers of
square waveforms from the top.
AM/FM/FSK modulation
Modulation for internal and exter-
nal signals can be made by built-
in AM/FM modulator. FSK modu-
lator to modulate sub carrier with
digital signal is also built-in.
Photo shows AM modulation and
FM modulation from the top.

Setting for arbitrary waveform
Generation of arbitrary waveform with
front panel keys. Operations such as
each data point input, drawing line be-
tween the points, inserting defined
waveform, etc. from front panel keys are
possible. Displaying menu and wave-
form on the 160x80 dot graphic LCD
enables easy data input with confirma-
tion of the process.

Process for generation of the waveform on the photo
is as follows.
1. Download defined waveform.
2. Load enlarged/reducted sine waveforms onto the
plus peak of the initial waveform.
3. Load line between two data points.
4. Add glitch waveform( data point input)
5. Add noise signal onto the minus peak of the ini-
tial waveform.

Generation of arbitrary waveform using applica-
tion software
Using waveform editter Wave-X makes it easy.
It includes pencil function as well as variety of 9kinds of de-
fined waveforms.
Reading waveform memory data from the unit, serving data,
and printing data are possible.
Wave X can be downloaded from our home page.

Phase setting function
Starting phase for non-continuous
mode signal can be set. Setting
range is within ± 360°with 0.1°
resolution. Photo shows setting
