The Keysight (Agilent) E1445A is a high-performance Arbitrary Function Generator designed as a C-size, 1-slot, message-based VXI module. Featuring 13-bit vertical resolution, a maximum sampling rate of 40 MSa/s, and a deep 256 kSa waveform memory, it offers exceptional flexibility for generating standard waveforms (sine, square, triangle, ramp) and complex user-defined arbitrary waveforms. Its advanced sequencing capabilities enable the creation of highly intricate, long waveforms from smaller, reusable segments, making it ideal for automated test environments.
