Keysight / Agilent / HP E1340A Arbitrary Function Generator Replacement Board

The Keysight/Agilent/HP E1340A is a VXI-based arbitrary function generator replacement board delivering signal generation across DC to 15 MHz with 12-bit resolution and 42 MSa/s sampling. This B-size, single-slot module combines arbitrary waveform generation with standard waveforms (sine, square, ramp, triangle, sin(x)/x, noise, haversine), linear frequency sweep, FSK modulation, and waveform hopping for comprehensive signal conditioning in test systems.
