Astronics Test Systems Inc. Racal Instruments™ 1260-152/172 High-Frequency Coaxial Switch Plug-In The Racal Instruments™ 1260-152/172 is a high-frequency coaxial switch plugin. It can be used in either the Racal Instruments™ 1260-100 Adapt-A-Switch® VXI carrier or the Racal Instruments™ 1256 GPIB/RS-232 switching mainframe. This switch plug-in is ideal for high-frequency RF switching, as required in the Telecom and Communications markets. Key Features • 1260-152: 1.2 GHz bandwidth • 1260-172: >900 MHz bandwidth • 50 Ω And 75 Ω versions • Coaxial interface • 17 channels of SPDT switches • Ideal for high-frequency RF switching Product Information The 1260-152/172 maintains excellent signal integrity as a result of the high-frequency RF relays and the matching coaxial interface. The 1260-152 has a -3 dB bandwidth of 1.2 GHz at 50 Ω. The 1260-172 has a -3 dB bandwidth of 900 MHz at 75 Ω. Both are comprised of 17 channels of SPDT switches and are capable of switching up to 30 V. SPDT switches may be used independently or cascaded externally to make a multichannel RF multiplexer. For example, 3 SPDTs can be cascaded to conﬁgure a 1X4 RF multiplexer. All relays on the 1260-152/172 are electromechanical, making all inputs/outputs interchangeable to meet test requirements. Coaxial connector housings (shells) are included with each switch card; however, the connector pins must be purchased separately. Cables supplied with the coaxial pins at both ends (tested up to 1 GHz) are optional and may be ordered in 2, 6, or 12-foot lengths. With the cable cut in half, you can support 2 channels per cable and alleviate the need for a special crimp tool. See ordering information on the second page of this data sheet. 949.859.8999; 800.722.2528; atssales@astronics.com; www.astronicstestsystems.com Copyright © 2014 Astronics Test Systems Inc. When used with the Adapt-a-Switch™ carrier, the 1260-152/172 requires a Racal Instruments™ Option 01T to communicate with the switch cards and to provide both message-based operation for ease of use and register-based operation for maximum speed. When used with the 1256 Switching Mainframe, no controller is required, and message-based operation is available. The Adapt-a-Switch™ line provides VXIplug&play support for frameworks based on Microsoft Win32® application programming interface, including drivers for LabWindows™/CVI and LabVIEW™.

Astronics Test Systems Inc. Ordering Information Note: When the 1260-152/172 is used in a VXI mainframe other than a 1256, a Racal Instruments™ Option 01T Smart Control Module must be installed in the mainframe’s leftmost slot. Note: Includes two mating connector housings with cable and strain relief. Pins not included. Pins can be ordered separately, either un-crimped or attached to a cable. 407742-003 : Racal Instruments™ 1260-152 High-Frequency Coaxial Switch Module, 50 Ω 407742-004 : Racal Instruments™ 1260-172 (Obsolete) High-Frequency Coaxial Switch Module, 75 Ω Accessories:...
