The 60-721A High Performance Video Multiplexer is designed for
switching RF signals in 75Ω systems at frequencies up to 1GHz. It
is ideal for monitoring applications that require the selection of one
channel to be routed to measuring equipment.
The automatic 75Ω termination of unused channels helps
maintain signal integrity and minimizes the possibility of
introducing unwanted responses. The common connection is also
automatically terminated when unused. Front panel LEDs adjacent
to each input connector provide identication of the active channel.
High signal isolation and low crosstalk ensure that an active
channel is not disturbed by signals on unselected channels. Careful
design ensures a smooth pass band response and insertion loss,
which is consistent on all signal paths. This can be easily calibrated
out to provide traceable measurements.
The 60-721A includes two expansion ports Exp1 and Exp2 which
allow the common signal to be routed to two further 60-721As. This
allows the easy construction of large multiplexers.
Controlling the MUX
The 60-721A is controlled through an LXI interface based on
Ethernet 1000base-T connectivity. It provides a quick and easy
method of installation and a simple way of controlling the unit in
a remote location through its API or built in soft front panel. The
ability to control the unit at a distance aids the testing of systems
without the need for a physical presence.

SECTION 2 - TECHNICAL DESCRIPTION
FUNCTIONAL DESCRIPTION
The 60-721A is a video multiplexer with up to 144 channels under the control of an LXI interface designed for the
routing of signals with frequencies up to 1GHz. The 60-721A can be, cascaded to create larger multiplexers by the
use of expansion connectors Exp1 and Exp2. A block diagram for the 72-channel version is shown in Figure 2-1.
Switch setting information for the unit is sent from the Embedded Processor to the 16:1 Multiplexer PCB via a Bridge
circuit. The switching data is in serial form and passes through digital isolation devices on the 16:1 Multiplexer
board before being received by the relay drivers. Ribbon cables transfer switching data and power to the relay
drivers on the 12:1 Multiplexer boards. The 16:1 Multiplexer distributes UUT signals to the six 12:1 Multiplexers
creating a 72:1 multiplexer. The 12:1 Multiplexers include switches that terminate unused switching channels - for
a detailed diagram of the switching arrangement, refer to Figures 2-2 and 2-3. 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.

Figure 2-4. Expansion
example for the 60-721A-003
Video Multiplexer. Two further
units can be cascaded from
the Exp1 and Exp2 ports to
create a 216:1 multiplexer.
The 60-721A can easily be expanded by linking the Exp1 and Exp2 ports to the Common connections of other
60-721A units. In the example shown in Figure 2-4, two 72-channel multiplexers are cascaded from one 72-channel
unit creating a single 216-channel video multiplexer. It should be noted that each multiplexer can only select one
of the 72 channels OR one of the two expansion ports. In the example below channel 146 has been selected, this
requires the Common and Exp2 of Unit 1, and the Common and 3rd channel of Unit 3 to be enabled. All other
channels are disabled and therefore terminated into 75Ω.

INSTALLING THE VIDEO MULTIPLEXER
The 60-721A may be mounted on a desk top or tted into a standard 19 inch rack (rack mounting anges are
supplied with the unit that can be tted to the sides of the front panel). When tting into a rack it is important to
provide adequate support using side brackets or runners, the mounting holes in the front panel anges are
designed only for securing the unit in the rack and must NOT be used to support the weight of the whole
unit.
The 60-721A relies upon forced air cooling for the power supply and processor area of the chassis. An internal fan
draws air through slots milled in the rear of the left and right side extrusions and expels air through a vent on the
rear panel. When positioning the chassis, make sure that there is adequate clearance to allow unrestricted air ow
through these vents. The locations of the air intakes and outlets are shown in Figures 3-1 and 3-2.
Power is supplied to the rear of the unit using a standard IEC power lead and the power on/off switch is located next
to the power inlet socket. The unit is supplied with a suitable Earthed mains power lead, If a different lead is used it
is important to ensure that an adequate Earth connection is present. When mounted in a rack, provision should be
made to allow access to the rear of the unit. This is to enable the operation of the power on/off switch and the Reset
button. The rear panel layout is shown below.
The Video Multiplexer is controlled by the host computer via an Ethernet interface. The RJ45 socket on the rear of
the unit can be connected to a hub or switch via an Ethernet cable to allow control over a local area or wide area
network. Alternatively a crossover Ethernet cable can be used to connect the unit to a laptop PC and local control
can be carried out isolated from a network. The IP address of the unit has to be manually or automatically congured
before it can be used on a network, please refer to the following section “Setting the IP Address” and the “LXI Getting
Started Guide” document to carry out this process.

SETTING THE IP ADDRESS
To use the 60-721A Video Multiplexer over a LAN connection it should be set up and congured as described in the
“LXI Getting Started Guide” document in Appendix B of this manual.
If the IP address is to be set manually and before connecting to a network, contact your IT department so they can
give you the correct settings for:
• IP Address
• Subnet Mask
• Default Gateway
• DNS Server(s)
Once you have the required information, the IP conguration window is used to manually set the IP address. This is
shown in Figure 3-4.
The current IP address setting of the 60-721A is indicated on an LCD display on the rear panel of the chassis.

Incorrect setting will result in a loss of communication and may also be indicated by a red LAN LED on the front
panel. If this does occur press and hold the LAN Reset button on the back panel of the device for a full factory reset
(see Section 6 “Troubleshooting” for details).
