ET33C Function Signal Generator manual

1. Basic introduction

ET33C series two-channel function/arbitrary wave generator (hereinafter referred to as ET33C
series) adopts direct digital frequency synthesis technology, which can output signals with high accuracy,
stability and low distortion.
ET33C series has five models: ET3320C, ET3330C, ET3340C, ET3350C, ET3360C, the highest
output frequency is 20MHz, 30MHz, 40MHz, 50MHz and 60MHz respectively.
