LeCroy ArbStudio 1104 Arbitrary Waveform Generator, 4 channel

The LeCroy ArbStudio 1104 is a 4-channel arbitrary waveform generator delivering high-fidelity signal synthesis from 2 µHz to 125 MHz. Built for engineers requiring precise waveform creation, it combines arbitrary waveform generation, Direct Digital Synthesis (DDS), and standard function generation in a single instrument. With 1 GS/s sample rate per channel, 16-bit resolution, and 2 Mpts memory per channel, the ArbStudio 1104 handles everything from basic sine waves to complex custom waveforms.

Modulation support spans AM, FM, PM, ASK, FSK, and PSK. Optional digital pattern generation (36 channels on the -D variant) extends functionality into mixed-signal test environments. Multiple units synchronize via AS-SYNC cables for scaled channel counts up to 32 channels.
