Synchronized Periodic Trigger
In the absence of an external customer input signal (TRIG‐IN), the Zi‐8CH‐SYNCH ProBus module can use an
internal fixed frequency clock to trigger the Master and Slave oscilloscopes automatically at a predefined
interval. The Master and Slave oscilloscopes are set to this mode by selecting periodic mode from the Trigger
dialog on the Master oscilloscope's user interface when the Zi‐8CH‐SYNCH is connected.
In this mode, the absence of a valid TRIG IN signal results in a forced trigger using a fixed frequency clock inside
the Zi‐8CH‐SYNCH module to generate a time stamp (the information is used to re‐synchronize the waveforms
on the Slave oscilloscope) and automatically force both the Master and Slave oscilloscopes to acquire data at
predefined intervals.
Controlling Synchronized Oscilloscopes
All display control of Master + Slave acquisitions comes from the graphical user interface on the Master
oscilloscope. When the Zi‐8CH‐SYNCH module is connected properly, all channels may be turned ON or OFF
from the Master. Channel setup (vertical, pre‐processing, etc.) is completed on the Master or on the Slave
oscilloscope, specifically where the acquisition originated for that particular channel.
Triggering is via Edge trigger only from the Master oscilloscope using the common acquisition trigger pulse, or
the oscilloscopes may be triggered at the predefined interval using asynchronous operation.
Upon completion of a successful trigger, data transfer from the Slave to the Master oscilloscope is initiated for
all channels, and all are displayed on the Master oscilloscope grid display. Trace descriptor labels for each
acquired channel are also shown on the Master oscilloscope. When shown on the Master oscilloscope's display,
Slave channels are renumbered 5, 6, 7, 8 (for Slave 1, 2, 3, 4 channels) in the case of synchronizing two
oscilloscopes with 16 GHz or lower bandwidth, or 6 and 7 (for Slave 2 and 3 channels) in the case of
synchronizing two oscilloscopes with 20 GHz or higher bandwidth.
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).
