Chapter 2 CHEETAH 128 SERIES INTRODUCTION
2.1 CHEETAH 128 SERIES PRODUCT OVERVIEW
Cheetah 128 series switchers are full-featured video matrix switchers capable of handling Serial
Digital Interface (SDI) and High-Definition Television (HDTV), as well as other non-standard
digital signals, in the same frame. Copper and optional fiber input and output modules provide for
maximum flexibility.
2.2 CHEETAH 128 SERIES SWITCHERS FEATURES
2.2.1 Cheetah 128 Series Switchers Features Overview
All Cheetah 128 series (128NE, XE, and WE) video matrix switchers offer alarm support, switch
confirmation, block checking, and power-out-of-range indicators. A key feature of the 128NE
and 128WE switchers is the Matrix Watchdog™ redundant crosspoint (matrix) option. For
critical routing requirements of live, on-air situations or other critical distribution facilities, a
redundant crosspoint can be added to manually swap-over in case of failure. This feature is
offered as an option in our basic configurations. The Watchdog™ option includes monitoring
capabilities to alert personnel of a crosspoint failure.
The Cheetah 128XE is an extremely flexible routing switcher that can be configured in three
ways. First, the 128XE expands outputs for a basic 128X256 configuration. Next, the 128XE is
offered as a 128X128 that offers output option slots for in-frame format conversion cards. In this
configuration, three options are available:
•HD to SDI down-conversion,
•SDI to Composite Analog Video and digital Fiber Output
•Dual outputs
•Crosspoint monitoring in Watchdog™ options.
The 128XE is further enhanced with an option to support either internal fiber or coax I/O.
Finally, for those applications that require only a portion of the frame to be configured for output
options, the 128XE is flexible enough to accommodate the following seven additional sizes:
•128x144: Output options for 17-128 (first option slot used for 129-144)
•128x160: Output Options for 33-128 (first two option slots used for 129-160)
•128x176: Output Options for 49-128 (first three options slots used for 129-176)
•128x192: Output Options for 64-128 (first three options slots used for 129-192)
•128x208: Output Options for 80-128 (first three options slots used for 129-208)
•128x224: Output Options for 92-128 (first three options slots used for 129-224)
•128x240: Output Options for 112-128 (first three options slots used for 129-240)
The 128WE includes non-expandable outputs (similar to the 128NE) with output options (similar
to the 128XE) and has redundant crosspoints.

Chapter 3 CHEETAH 128 SERIES CONFIGURATION MATRIX
3.1 CHEETAH 128 SERIES CONFIGURATION MATRIX OVERVIEW
This section includes a list of all of the major components for the Cheetah 128NE, 128XE, and
128WE Video Matrix Switchers chassis/frames (models).
When discussing output options and expandable outputs, the meanings are as follows:
•Output Options pertains to which cards can go into a particular output slot in the frame for a
specific configuration(s). This includes cards that offer signal expansion or conversion such
as dual outputs, HD to SDI down-conversion, Digital to Analog conversion, and electrical
(copper) to fiber conversion. Option cards are offered as “piggy-back” modules that plug
onto the base output combiner card.
•Expandable Outputs pertains to the number of outputs that a particular frame can be
expanded beyond the basic configuration (e.g., 128 or 256 outputs).
Table 3-1 includes only the active cards that are required for the individual Cheetah 128 series
chassis configurations. The blank covers (if necessary) are required for the card locations that are
not used (to satisfy chassis component cooling requirements).
Table 3-2 includes PESA Switching Systems, Inc. part numbers for the corresponding Cheetah 128
Series cards, power modules, and other components

Chapter 4 CHEETAH 128 SERIES VIEWS AND SPECIFICATIONS
There are two chassis’ sizes that house the Cheetah 128 Series switchers, which are the 6RU and
4RU chassis. The 128XE and the 128WE are housed in a 6RU chassis and the 128NE is housed in
the 4RU chassis. This section will pictorially display the internal layouts of the switchers, depict
the connections, and list the system specifications.
This section will be subdivided into the following subtopics:
•Cheetah 128NE Frame Views
•Cheetah 128XE and 128WE Frame Views
•Cheetah 128NE, 128XE, and 128WE Specifications
