UBZR1 Modulation Module

Summary/Usage

UBZR1's Modulation module implements the modulation matrix.

Functional Description

The Modulation (Mod) module is basically a set of four analog multiplexers, that connect four modulation sources to eight modulation destinations. To save digital selection bits, two multiplexers are switched in lock-step. i.e. can not be switched independently.

Performance Specifications

• The four modulation input signals are limited in voltage range to −5 V to +5 V
