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.

AFG-4000 series arbitrary function signal generators, which provide 25 MHz to 250 MHz
bandwidth, single-channel and dual-channel designs, and feature 1 Hz high-resolution in the whole frequency bandwidth. The series has built-in standard signals including sine wave, square wave, triangle wave, pulse wave, noise wave, harmonic wave, etc.
The highest bandwidth 250 MHz model provides 1.25 GSa/s sample rate; the mid-range
models ranging from 35 MHz to 100 MHz provide 500 MSa/s sample rate; and the 25 MHz
entry-level models have a sample rate of 125MSa/s. For vertical resolution, the 35 MHz to
250 MHz models feature 16-bit resolution, and 25 MHz entry-level models provide 14-bit
resolution.

In addition, the AFG-4000 series provides the modulation signal outputs of AM, DSB-AM,
FM, PM, PWM, ASK, PSK, BPSK, QPSK, FSK, 3FSK, 4FSK, OSK, SUM, signal sweep
outputs, and the Burst and Counter functions. AFG-4125AE has the built-in amplifier
function.

The AFG-4000 series has the built-in 50 ohm/high impedance switching function, and
is equipped with an 8-inch high-resolution TFT LCD, and the models above 35 MHz
are equipped with the touch screen function. For communications interfaces, models
above 35 MHz are built-in USB and LAN communications interfaces.
