AFG-2225 Description
The GW Instek AFG-2225 is it's first basic level dual-channel
arbitrary function generator, which provides superior features in its class. Both channels are equipped with
same characteristics to fit dual-signal applications such as differential or IQ signaling. The outstanding cost-performance
value makes the AFG-2225 a practical instrument to accelerate the development process. The major features for
both channels include 10Vpp output amplitude; 25MHz frequency bandwidth with 1uHz resolution; built-in waveforms
of Sine, Square, Ramp (Triangle) and Noise. As to the 1%~99% adjustable duty cycle of Square waveform can be
used as pulse signal sources. For the arbitrary waveform, user can edit the 66 built-in waveforms or create
a whole new one. Moreover, AFG-2225 carries features of AM/FM/PM/FSK/SUM Modulation, Sweep, Burst and Frequency
Counter, which can be applied to various communication fields.
Dual-channel Signal Output Capability
In most two-channel signals applications, such as digital modulation
and vehicle electronic simulation signals, the similar or identical waveform capabilities are required for both
channel outputs. Unlike other dual-channel AFG in this class, AFG-2225 is fully equipped with equal capabilities
on dual outputs. Most of dual-channel arbitrary waveform generators in this basic level cluster offer one major
channel and one minor channel, in which the minor channel only provides less functions or inferior performances.
This sort of non-full-function dual-channel AFGs can not meet the requirements of reality.
High-flexibility of Arbitrary Waveforms Editing
AFG-2225 provides 120MSa/s sampling rate, 10-bit vertical resolution,
4k-point waveform length, and the maximum waveform repeated rate of 60MHz, regarded as an outstanding arbitrary
waveform capability. There are four ways for AFG-2225 to generate customized arbitrary waveforms, which are
editing waveform via PC software, point-by-point editing on the panel, loading CSV file and loading the captured
waveform from GW Instek GDS-Series Oscilloscopes.
The PC software editing and point-by-point editing particularly provide the way to create the user-defined and
post-modification waveform. CSV file loading capability allows AFG-2225 to produce the waveforms with complicated
math operation result. Engineer can use PC math software to process the integral and then send the results in
CSV format to AFG-2225. With the link to GW Instek GDS-series Digital Storage Oscilloscopes (DSOs), the waveforms
of interest can be captured by DSO and then reconstructed by AFG-2225. User can capture the waveform during
the operation and then reconstructed by AFG-2225 for further analysis or diagnosis in the laboratory. Thus,
plus the dual-channel feature, numerous derivative applications of capturing signal can be achieved.
