The HP 3488A provides single switching with the integrity and isolation needed for high-performance production test systems. It also offers a flexible, low-cost interconnection for automating experiments on the bench and for developing tests in the lab. The HP 3488A is designed to hold up to 5 of the following switch and control modules: Flexible Switching The HP 3488A is an economical approach to flexible switching through plug-in modules. You can select the right combination of switching functions to meet both performance and budget needs. . Custom circuitry can also be implemented on breadboard modules. Versatile Performance The HP 3488A can store up to 40 complete switch configurations for convenient recall in automated test programs. Switch operation can be done Break-before-make and recallable switch configurations can be combined in a programmable scan list. The HP 3488A uses removable screw connectors that provide easily interchangeable wiring for each test. Built-in self-test assures proper operation. - Bloc comutare universal - General Purpose Relay (Option 011/HP 44471A) This module consists of 10 SPST independent relays for general signal switching and control of external devices. Quality connections make this module ideal for switching signals when multiplexing is not required, or for supplying switchable power to the device under test. - Bloc multiplexor cu relee - Matrix Switch (Option 013/HP 44473A) Option 013 offers highly flexible switching with a 4 X 4, 2-wire matrix. Any combination of 4 input channels may be connected to any combination of 4 output channels. Each cross point or node in the matrix uses a 2SPST relay to switch 2 lines (Hi and Lo) at a time. Multiple 4 X 4 modules can be connected to form larger matrices. Multiplexers can be used in conjuction with this larger module to effectively expand the number of inputs and outputs of the matrix. - Bloc iesiri/intrari digitale - Digital I/O (Option 014/HP 44474A) This module offers 16 very flexible bidirectional I/O lines and 4 TTL-compatible handshake lines for sensing and control of external devices. The digital inputs can be used to sense contact closures to ground. Each channel provides current sinks for remote switching of external relays, such as the HP 33311 series coaxial switches. : | | | | | | | | | | | |
