# CH1 CH2 25MHZ TRUE DUAL CHANNEL ARBITRARY FUNCTION

25MHz TRUE DUAL CHANNEL ARBITRARY FUNCTION GENERATOR Ce E el №: Host | Device | Software Equivalent Dual-Channel Provides Augmented Value for Customers GW Instek is launching AFG-21225, its 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-21225 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 19%~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-21225 carries features of AM/FM /PM/FSK/SUM Modulation, Sweep, Burst and Frequency Counter, which can be applied to various communication fields. In addition to the intuitive and friendly user interface, the 3.5-inch color LCD displays the comprehensive operation information including the true waveform presented at the output. USB Host and Device interfaces are equipped to link the AFG-21225 with other devices, which provide the flexibility of waveform generation for more practical usages. With link to GW Instek GDS-series Digital Storage Oscilloscopes (DSOs), the waveforms of interest can be captured and reconstructed. User can also use the arbitrary waveform PC software to edit the waveform and then send to AFG-21225 directly, or save the waveform into flash drive and then transfer to AFG-21225. Full-Functions equipped 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-21225 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. Correlated Functions of Dual-channel Outputs The two channels can be used in either independent or correlated configuration. AFG-21225 provides three correlated functions which are Couple, Tracking and Phase functions. For Couple function, two signals with a ratio or offset in amplitude or frequency can be generated. One of two signals with adjustable offset frequency is an example which can form the two-tone signals for testing the third order inter-modulation distortion of an amplifier. With Tracking function, two differential signals with equal-frequency, equal- amplitude but inverted phase can be produced. Examples such as PECL, LVPECL and LVDS digital signals or automotive sensors like temperature, speed signals are all able to be simulated by tracking function. The Phase function is designed to create two signals with specified phase offset. When user wants to create two quadrature (sine and cosine) signals, the phase offset is set to be 90 degrees in the Phase function. In conclusion, compared with other arbitrary function generators only equipped with phase function, AFG-21225 provides great convenience to fulfill the various challenges coming from modern electronic industries. High-flexibility of Arbitrary Waveforms Editing AFG-21225 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-21225 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-21225 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-21225. 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-21225. User can capture the waveform during the operation and then reconstructed by AFG-21225 for further analysis or diagnosis in the laboratory. Thus, plus the dual-channel feature, numerous derivative applications of capturing signal can be achieved. ar AFG-21225 FEATURES * Wide Frequency Ranges From 1 pHz — 25MHz (sine wave) * 1 Hz Resolution in Full Range o Built-in Standard 120MSa/s, 10bit, 4k Points Arbitrary Function for Both Channels True Dual-Channel Output, CH2 Provides the Same Characteristics as CH1 * Dual-Channel Supports Couple, Tracking, Phase Operations * 1% ~ 99% Adjustable Duty Cycle for Square Waveform Friendly User Interface for Easy Parameter Setting and Parameters Display o Multiple Editing Methods to Edit Arbitrary Waveform Easily e Built-in Standard AM/FM/PM/FSK/SUM/ Sweep/Burst and Frequency Counter * USB Host/Device Interface for Remote Control and Waveform Editing APPLICATIONS * Power Supply/Transformer Simulations Traditional/Motor Power Applications Laboratory and Educational Research * Pulse Signal as Trigger or Synchronization * Automotive Electronics Applications L 1ISO-TECH SPECIFICATIONS WAVEFORMS ARITRARY FUNCTION FREQUENCY CHARACTERISTICS OUTPUT CHARACTERISTICS SINE WAVE CHARACTERISTICS SQUARE WAVE CHARACTERISTICS RAMP CHARACTERISTICS PULSE CHARACTERISTICS AM MODULATION FM MODULATION PM FSK SUM SWEEP BURST FREQUENCY COUNTER DUAL CHANNEL FUNCTION EXTERNAL TRIGGER INPUT EXTERNAL MODULATION INPUT TRIGGER OUTPUT SAVE/RECALL INTERFACE DISPLAY POWER SOURCE POWER CONSUMPTION OPERATING ENVIRONMENT OPERATING ALTITUDE STORAGE TEMPERATURE DIMENSIONS & WEIGHT Sample Rate Repetition Rate Waveform Length Amplitude Resolution Non-Volatile Memory Range Resolution Accuracy Amplitude Offset Waveform Output Sine/Square Ramp Stabili A Tolerance Range Accuracy Resolution Flatness Units Range Accuracy Impedance Protection Harmonic Distortion Rise/Fall Time Overshoot Asymmet Variable Duty Cycle Linearity Variable Symmetry Period Pulse Width Overshoot Jitter Carrier Waveforms Modulating Waveforms Modulating Frequency Depth Source Carrier Waveforms Modulating Waveforms Modulating Frequency Peak Deviation Source Carrier Waveforms Modulating Waveforms Modulation Frequency Phase Deviation Source Carrier Waveforms Modulating Waveforms Modulation Frequency Phase Deviation Source Carrier Waveforms Modulating Waveforms Modulation Frequency Phase Deviation Source Waveforms Type Start/Stop Freq Sweep Time Source Waveforms Frequency Burst Count Start/Stop Phase Internal Period Gate Source Trigger Source N-Cycle, Infinite Range Accuracy Time Base Resolution Input Impedance Sensitivity Phase Tracking Coupling DSOlink Type Input Level Slope Pulse Width Input Impedance Type Voltage Range Input Impedance Frequency Type Level Pulse Width Maximum Rate Fan-out Impedance 10 Groups of Setting Memories USB(Host & Device) 3.5 TET LED AC100 ~ 240V, 50~60Hz 25W (Max.)
