This document compares the specifications of four pulse generators from Quantum Composers Inc: the Sapphire 9500+, Sapphire 9520, Emerald, and Emerald. It provides a side-by-side comparison of each pulse generator's pulse generation capabilities, internal and external triggering features, output channels, communications options, and pricing for various channel configurations. The Emerald and Sapphire 9520 models offer the highest resolution, accuracy, and lowest jitter compared to the other models. Pricing ranges from $995 for a 2-channel Sapphire 9500+ to $5,780 for an 8-channel Emerald.
