SECTION 2 - TECHNICAL DESCRIPTION
FUNCTIONAL DESCRIPTION
The 60-711 is a single or dual 24 x 8 video matrix. Much of this description assumes the product supplied is the
dual version and references to dual matrices or extended matrices should be ignored if the device is a single
matrix. The matrices have been designed to operate in a 75Ωsystem, the impedance commonly used for video
applications.
For dual versions the two matrices can be set independently. In addition, part or all of the matrices can be
connected together to extend the size of the matrix. With all the channels connected together a 48 by 8 matrix can
be formed. The matrix can also be set to other congurations by not closing all the matrix isolation relays. Each 24
x 8 matrix is built on a separate circuit board, Bank A is on the upper PCB and Bank B is on the lower PCB
Switch setting information for the matrix is sent from the Embedded Processor to the relay drivers on the Matrix
Boards via a Bridge Card. Programming information for the processor is sent to the unit via the LAN interface from
a remote computer using the unit’s unique Ethernet address. Programming documentation for the unit as well
as data for Pickering’s other LXI compatible switching products is stored in the embedded processor and can be
downloaded over the LAN interface. Status LEDs on the front of the chassis indicate the condition of the unit and
the LAN connection.

MAKING CONNECTIONS TO THE MATRIX
The matrix RF connections are mounted on the front panel of the 60-711 and can be 75Ωmini SMB, 75ΩMCX
or 75Ω BNC types. The dual versions have two rows of mini SMB or MCX connectors, or four rows of BNC
connectors.
The unit can be ordered with 50ΩSMB connectors (60-711-721), these connectors can mate to 75ΩSMB
connectors without damage, but it is recommended that 50Ωconnectors are used even in 75Ωsystems. Cables
connecting to the 60-711 should be 75Ω.

The 60-711 Dual Video Matrix consists of two separate 24 x 8 coaxial matrices which can be used independently
(see Figure 2-2). The Y axes of the matrices can be connected together using two banks of Matrix Isolation Switches
allowing one or all of the Y lines to be interlinked. This enables many different congurations to be realised, for
example, closing all Matrix Isolation Switches creates a 48 x 8 matrix (see Figure 2-3). The Matrix also uses Y
Isolation Switches to connect the Y axis to the front panel connectors. These allow unused Y connections to be
disconnected from the matrix and preserve overall bandwidth. The Matrix can also be used with all Y Isolation
switches open in an “X Axis Only” conguration, this is outlined overleaf.

Once the size of the matrix has been congured using the matrix isolation switches, it can be used in one of two
ways:
X and Y access. In this case the Y bus isolation relays are closed to connect the Y connectors to the matrix and
an interconnection between X and Y is obtained by operating one relay in the matrix. This method has a slight
perfomance advantage because a single crosspoint is closed for each interconnection, but may not be the most
efcient use of the matrix.
X access only. All signals are connected only to the X axis, and an interconnection is made by closing two relays
on the same Y bus line. This method can provide greater exibility, giving a greater combination of interconnections
through the matrix. However, the width of the Y bus restricts the number of simultaneous interconnections that can
be made, in the case of the 60-711, the maximum is 8. For the best performance the Y isolation relays should be
kept off, isolating the front panel Y connectors and maximizing the bandwidth of the matrix.
The 60-711 has been designed to ensure that signals have minimal loss and VSWR when in used in a 75Ωsystem.
If one input terminal is connected to more than one output terminal it will have a signicant impact on the bandwidth
of the switching system.
If the 60-711 is intended for use in a 50Ωsystem again the bandwidth will be affected. The user should use a 75Ω
to 50Ωadaptor on each interface.
