25MHz~250MHz frequency bandwidth selections to meet diverse signal generation needs!

AFG-4000 arbitrary function generator series is GW Instek’s first arbitrary function generator series to be equipped with an 8” large touch screen. The frequency bandwidth of the single-channel models is 25MHz, and dual- channel models feature 250MHz/100MHz/80MHz/60MHz/35MHz/25MHz frequency bandwidth selections. The entire series provides high resolution of 1μHz and has built-in standard waveforms such as sine wave, square wave, triangle wave, pulse wave, noise wave, harmonic wave, etc. The highest bandwidth 250MHz model provides 1.25GSa/s sample rate; the mid-range models ranging from 35MHz to 100MHz provide 500MSa/s sample rate; and the 25MHz entry-level models have a sampling rate of 125MSa/s. For vertical resolution, the 35MHz~250MHz models feature 16-bit resolution, and 25MHz entry-level models provide 14-bit resolution. In addition, in terms of memory depth, dual channel 25MHz ~250MHz models provide 10M memory depth, and entry-level single channel 25MHz models provide arbitrary waveform editing function with 16k memory depth. The entire series has built-in 146 arbitrary waveforms for editing and output.

The main differences between each model are shown in the table below:

* Built-in Power Amplifier function

The dual-channel models provide dual-channel related settings such as frequency coupling, amplitude coupling and tracking, allowing users to quickly set the output related to the two channels. In terms of modulation function, the AFG-4000 series provides AM, DSB-AM, FM, PM, PWM, ASK, PSK, BPSK, QPSK, FSK, 3FSK, 4FSK, OSK, SUM and other modulation signal outputs. Standard functions include Sweep and Burst outputs and the Counter function. AFG-4125AE has a built-in power amplifier. The power output of the amplifier reaches 10W, and the amplification factor reaches 10 times to produce a maximum output of 22V. The independent input/output power amplifier provides a bandwidth range from 5Hz to 100 kHz, which can be used for audio signal and other application requirements.

The AFG-4000 series is equipped with an 8-inch high-resolution TFT LCD, and models above 35MHz are equipped with the touch screen function. The configuration of touch screen makes inputting parameters more convenient. Users only need to touch parameters such as Frequency, Amplitude or DC offset, and a numeric input window will appear on the screen. Users can intuitively input parameters through this window or the numeric keys on the AFG-4000 panel. Through the 8" large screen, touch screen and diverse built-in waveforms, users can control it at will to meet their signal generation needs.

As for the interfaces, the 25MHz models: AFG-4125E/ 4125AE/ 4225E have built-in USB Host/Device interfaces, and the models with higher bandwidths ranging from 35MHz to 250MHz come standard with USB Host/Device and LAN interfaces.
