Introduce GW Instek AFG-3081
The AFG-3000 Series is an arbitrary waveform generator designed for industrial, scientific research, and educational applications. The series comes in bandwidths of 80MHz (AFG-3081) and 50MHz (AFG-3051) with built-in multiple standard waveforms to meet users’ diversified needs.
The AFG-3000 Series also provides a high 16-bit resolution, 200MSa/s sample rate, and a 1M memory depth for editing arbitrary waveforms directly through the intuitive user interface. The Direct Waveform Reconstruction (DWR) function enables users to directly import waveforms from a GDS-2000 Series oscilloscope to the AFG-3000 via USB host, allowing users to edit waveforms and enhance measurement efficiency.
In addition, the AFG-3000 Series has switchable 50 Ohm and Hi-Z Impedances, built-in On-Screen Help for operation conveniently. Complete parameter settings and waveform can be displayed through a 4.3-inch high-resolution TFT LCD. Through USB, RS-232, and GPIB, users can use dedicated PC software or IEEE488.2 commands to edit waveforms.
