AFG-2125 – Arbitrary Function Generator (25 MHz)
The AFG-2125 is GW-INSTEK's 25 MHz model in the AFG-2100 series of DDS-based arbitrary function generators. The product generates standard waveforms and arbitrary traces via digital input or PC software, and displays parameter information on a 3.5" LCD. The AFG-2125 provides the basic measurement and signal output capabilities specified for the AFG-2100 series.
What the product does
The AFG-2125 generates sine, square (pulse), ramp/triangle, noise, and arbitrary waveforms with a 20 MSa/s sample rate and 10-bit vertical resolution. The unit includes internal memory for arbitrary waveforms (4k points) and supports adjustable duty cycle for square pulses. As an AFG-2100 model, it also offers AM/FM/FSK modulation, sweep, and a built-in frequency counter.
