The brand new AFG-100/200 Series USB modular arbitrary function generator has four models for
selections. The AFG-100/200 Series arbitrary function generator with many unique features such as
light weight, handy, and USB interface compatible is an ideal choice for the applications at the
general laboratories in applying stand-alone operation or collocation with the GDS-2000A Series
digital oscilloscope.
The model, channel, and power arrangements of the AFG-100/200 Series are as follows:
AFG-125 AFG-125P AFG-225 AFG-225P
Channels 1 1 2 2
DC Power NA Yes NA Yes
DC power selections include 2.5V, 3.3V, and 5V.
One external 5V power supply (optional GPA-501) and PC software are required to independently
operate the AFG-100/200 Series. When the AFG-100/200 Series is collocating with the GDS-2000A
Series digital oscilloscope, the USB port of the GDS-2000A Series will provide the AFG-100/200
Series with necessary power.
The main features of the AFG-100/200 Series are output amplitude of 2.5Vpp (connecting with a
load of 50 ohms), frequency range reaching 25MHz, frequency resolution of 1u Hz, and built-in
sine waveform, square waveform, triangle waveform, and noise signal. Square waveform can adjust
the duty cycle from 1% to 99% and it can be utilized as pulse signal. Users, via the GDS-2000A APP,
can select from the 66 built-in function waveforms to conduct arbitrary waveform editing. The AFG-
100/200 Series, with functions of AM/FM/PM/FSK/SUM modulation, frequency sweep, burst and
coupling, is suitable for various communications applications.
The AFG-100/200 Series provides arbitrary waveform sampling rate of 120 MSa/s, 10 bit resolution
and arbitrary waveform editing function with 4k point memory to produce true point-by-point
arbitrary waveform output. The easy-to-use external software interface allows users to quickly and
conveniently operate the AFG-100/200 Series.
The AFG-100/200 Series connects the GDS-2000A series digital oscilloscope through the USB
interface to directly duplicate and produce the retrieved waveform signals. Users can edit the required
waveforms by the external computer software and send the edited waveforms to the AFG-100/200
Series to produce signals. The external computer program supports importing CSV format files.
AFG-225/225P dual channel models support independent channel or related channel applications.
Three related functions are coupling, tracking and phase.
* The coupling function allows users to freely set ratio and offset values for frequency and amplitude
of both channels to realize that all parameters are simultaneously effective for both channels. The
measurement of the Third-Order Intercept Point for an amplifier and the simulations of two different
frequency oscillators outputting signals are two application examples for the coupling function.
* The tracking function can produce 180 degree phase offset differential signals with same frequency
and amplitude.
* The phase function allows users to freely set phase parameters for both channels such as sine and
cosine waveform signals.
The sum modulation function can sum up two signals into one and output this signal via one
channel. One of the related applications is to sum up sine waveform and noise to execute speaker
distortion tests.
