Data Sheet
High-performance functions
This new range of DDS generators comprises three models, including two 
(GX 310-P and GX 320-E) available in a 100%-programmable version with 
an SCPI standard USB link and Ethernet on the GX 320-E. 
The GX 305 and GX 310 are ideal for education and technical training, as 
well as for R&D, test and production technicians.
The GX 320 (20 MHz) offers additional functions for higher education, R&D 
engineers and scientific research. 
The  DDS  technology  represents  a  major  step  forward  for  function 
generators, with a large number of improvements:
- exceptional accuracy and stability
- spectral purity
- low phase noise
In addition, these generators sweep a wide frequency range while keeping a 
constant phase when there are frequency jumps.
Performance and flexible use:
Adjustment of the frequency guaranteed stable to the nearest digit and 
a smart accelerator with automatic range changes for the frequency
Automatic range changes  optimized for the "LEVEL and OFFSET" 
amplitude
Duty cycle adjustable without variation or division of the frequency 
"LOGIC" function for a quick, simple way of generating logical signals 
with directly adjustable thresholds
A rugged generator with 60 Vdc / 40 Vac protected outputs
Slaving and display of the frequency
Control and display of the AMPLITUDE with a choice of 
Vpp (peak/peak) or Vrms (root mean square) and the Vdc OFFSET
Control and display of the duty cycle (DUTY)
100 MHz frequencymeter, CAT I - 300 V
Modulation, Shift K & BURST functions (GX 320)
The GX 320 includes internal and external modulation (AM, FM), as well as 
linear and logarithmic sweeps. The Shift K function can be used for phase 
or frequency jumps.
With the BURST function, users can choose the number of cycles per time period. This function can be used for even more detailed analysis 
and detection of very short events.
It is also possible to set up several GX 320 generators in a cascade arrangement.
Synchronization  of  several  generators  in  a  cascade 
arrangement
The  "SYNC"  function  on  the  GX  320  allows  several  generators 
to be set up in a cascade arrangement to make a variable-phase 
multiple signal generator.
A first GX 320, used as the "Master", provides the other "Slave" 
instruments  with  the clock  used  to generate the  signals.  It  also 
supplies  the  synchronizing  pulse  to  start  all  the  instruments 
simultaneously. In this  way,  the phase shift of  each signal is 
controlled.
The "burst" function is widely used in optics, 
notably for checking the quality of crystals

Example 2: simulated Fourier synthesis
Synchronization of the generators (3 in this 
example) allows simulated synthesis of a 
square signal from its primary harmonics.

Channel 1: master (0°)
Channel 2: slave1 (120°)
Channel 3: slave2 (-120°)
