Racal Instruments 1256
The 1256 switching system is a high performance switching and control system in a compact 2U rack mountable package. The unit draws upon Racal's decades of experience as a major automated test equipment (ATE) switching supplier to set a new standard in switching systems. With the addition of an Ethernet 10/100 interface, Model 1256 easily connects to computers at remote locations.
Wide Range of Plug-Ins Model 1256 controls up to eight Adapt-a-Switch™ plug-ins for switching and digital I/O. These plug-ins provide a wide range of switching capability: high current to 13A, high voltage to 1kV, RF/microwave to 18GHz, and even digital I/O with 96 channels per plug-in. The user can easily configure these plug-ins into a high-performance, low-cost solution to satisfy any switch application. A single 1256 can accommodate any one of the following configurations, and countless others:
1152-point matrix
512-channel scanner/multiplexer
640 SPST switches
768 channels of TTL, CMOS, or open-collector digital I/O
High-Speed Switching The 1256 switching system reduces test times with its high throughput and timesaving advanced features. It scans more than 100 channels per second, and opens or closes more than 200 channels in less than 0.1 second.
Non-Volatile Memory The non-volatile memory stores up to 100 complete switch states and includes a separate automatic power-up state. In addition, the 1256 can store all user designated preferences such as RS-232 baud rates, GPIB address, and display settings and have these automatically restored at power-up.
In addition, users employing the remote interfaces can store and recall both module and path names.
Advanced Triggering The 1256 synchronizes with other equipment using the external trigger in/out signals. Coupled with the advanced scan list features, the triggering facilitates rapid, automated measurements with minimal intervention from the user or system controller.
Intuitive Front Panel Control The highly intuitive menu-driven interface consists of a display, four soft-keys, and a knob. This powerful interface provides easy access to all relay and digital I/O states, system preferences, and non-volatile memory features of the 1256 switching system.
GPIB and RS-232 Remote Interfaces The GPIB and RS-232 remote interfaces provide any terminal or computer with access to all standard features. The remote interfaces are IEEE 488.2 and SCPI compliant. In addition, the remote interfaces can access advanced features:
Path Level Switching - Assign names to relay paths for ease of reference
Include Lists - Automatically close multiple relays with a single command
Exclude Lists - Build large scanners using mutually-exclusive relay groups
Scan List - Define sequentially-closed relay groups
Trigger Delays - Time relay closures to coincide with external events
Switch Mode - Select make-before-break, break-before-make, or immediate relay closures
Confidence Mode - Automatically verify relay response
