1. Introduction
Safety Precautions
This manual describes the proper usage of the BIT-2100 Series Switch System. All usage beyond the
specifications or the intended use is not recommended and might cause impaired safety for the user.
Scope and Datasheet
This user manual does not cover specifications. Please also refer to the BIT-2100B Datasheet
(available from the BitifEye website).
This user manual is for the BIT-2100B Series Switch System, and does not cover the BIT-2100A Series
Switch System.
Intended Use
The BIT-2100 Series Switch System is intended to be used as test and measurement equipment.
This instrument is designed as laboratory equipment, and not intended for home use. The SMA
connectors allow connection to appropriate electronic circuits or other laboratory equipment, as long
as the specifications (see datasheet) are not violated.
The Ethernet and USB connectors allow to connect the BIT-2100 Series Switch System to standard
computer equipment for the purpose of remote control, as well as for software updates.
Typical use case might be:
•
multiplex several serial high-speed serial lanes of a source device to an oscilloscope, to
efficiently test all lanes of the device
•
multiplex a single serial high-speed signal source to the ingress ports of a multi-port device,
to test all receivers of the device
•
connect a four-port vector network analyzer to an eight-lane cable, to test all lanes without
manual re-connections
In all of these use cases, the benefit of using a switch system is that the tests and measurements can
be conducted without manual re-connections, and they can even be fully automated with software.
Terminology
This manual uses the following terminology:
•
mainframe
: the chassis with all internal components (power supply, CPU, control unit with
display, etc.), in which up to five modules can be mounted
•
module
: one of the five modules, which contain relays, that can be mounted into a
mainframe
•
relay
: an electromechanical switch; a module can hold up to six relays
•
path
: the state of a relay, i.e. which terminal is routed to which; typically indicated by an
integer number; 0 indicates that all terminals are disconnected
•
terminal
: an RF (SMA or 3.5 mm) connector of a relay
•
terminated
: terminated with 50 Ω into GND, also known as “absorptive”; see also page 9
•
unterminated
: left without termination, also known as “floating” or “reflective open”; see
also page 9
