Getting Started

Afterremovingallpartsfromthepackagingandpreparingyouroscilloscopes,usethefollowingtopicsto

properlysetupyourentiresystem.

Prerequisites

BeforesettingupyourZi‐8CH‐SYNCH,ensurethefollowing:

• Themasterandslaveoscilloscopesareeachconnectedtoyourinternalnetwork.

OR

Themasterisconnectedtotheslaveusingacrossovercable.

• The10MHzRefclockoutonthemasteroscilloscopeisconnectedtothe10MHz

Refclockinontheslave

usingtheBNCcableprovided.

• Thefirmwareonbothoscilloscopesisversion6.1.0.7withsoftwarepatch6.1.0.7c(orlater).
