1 GENERAL INFORMATION
1.1 Overview
The AT1700 series multiplexer switch offers a high performance, cost effective solution for broadband RF switching in headend environments. These switches are ideal for test measurement systems, such as the realWORX
monitoring system, where multiple CATV signals need to be tested through the same spectrum analyzer. The
1700 series is compatible with the AT2500HM series analyzers as well as with previous AT2000HM series spectrum analyzers.
Switch control is provided via serial port or manual control.

2 GETTING STARTED
2.1 Product Overview
The VeEX Inc. AT1700 Series comprises the AT1701 (16x1) and AT1702 (16x2) Multiplexers.
The AT1701 Multiplexer has 16 RF input ports and 1 output port. The output port can select any one of the inputs
or can be set to a NO SELECT (i.e. all-off) state.
The AT1702 Multiplexer has 16 RF input ports and 2 independently controlled output ports. Essentially it is two
16-to-1 multiplexers sharing the 16 inputs. Each of the output ports can select one of the inputs or can be set in
a NO SELECT (i.e. all-off) state.
All ports have a bandwidth of 1 GHz, a nominal 10 dB gain and >50 dB isolation.
Multiplexers can either be cascaded or outputs combined for exible selection of one signal source from a multiplicity of sources.
The AT1700 series is housed in a 1 RU, 12” deep chassis. Each unit has its own external power source.
The output ports can be controlled independently via the front panel buttons or remotely through an RS-232
connection. Communication IN and OUT connectors are provided for connecting to the controller and for “Daisy
Chaining” communications from one unit to the next.
The AT1700 switches may be used in combination with previous model AT1600 switches. Be sure that the communications conguration matches both models.
