Product Name: VXI Modules
Product Description
|
Pickering Interfaces have a range of very high density VXI
switching modules. All System 30 modules are SCPI programmed, Message
based, C sized cards. They are suitable for complex functional test
applications requiring very high density switching with fast switching
times.
The initial range includes very high density matrix modules
containing up to 2340 relays per module. With this level of density we
will be offering a "Switching System On A Card". System 30
matrix modules will be available both with and without automatic relay
self test. They are available in a wide variety of formats with many other
configurations available to order.
All System 30 cards are self contained message based VXI
modules, they do not require special master adapters to be added to the
first switching card (these convert VXI instructions into a propriety
serial local bus protocol, locking you into that cards manufacturer).
Built In RS-232 Port
All System 30 VXI modules have an RS-232 port built right on the front
panel. This offers the following significant advantages:
- Full SCPI command set functionally.
- RS-232 port allows easy familiarization and debugging of your final
VXI code from any RS-232 terminal.
- Module re-configuration may be done via RS-232 port (no banks of
confusing DIP switches). This is all assisted with built-in help
screens.
- Firmware updates may be downloaded from the Web (or floppy disc/CD
ROM) using the RS-232 port (firmware includes all code and gate array
configurations).
- May be used as an RS-232 controlled standalone switching module (no
VXI chassis or slot 0 controller required). Please contact Pickering
Interfaces for further information.
- Choice of 8 baud rates up to 57600 and higher.
Very High Density VXI Switching Pickering Interfaces
VXI cards offer very high density switching. Up to 2340 relays per
card, this is up to 10X the switching capacity of competing VXI switching
cards (from HP, Tektronix, Racal, etc). So one high density System 30
matrix card will have the equivalent switching capacity of a fully loaded
VXI chassis using competing modules. This greatly increases switching
density and will reduce overall system cost.
Reed Relays For Maximum Performance and Reliability
All high density switching cards use only high quality reed relays (not
inferior electromechanical relays as in most competing products), these
give very long life (over 100000000 operations) and very consistent
contact resistance in a hermetically sealed reed relay (very important for
low level signal switching).
SCPI Message Based Interface with Built-In Self Test
All modules have a built in 32 bit embedded microprocessor together
with a custom gate array for fast loading of switching patterns. Operating
speed is close to register based modules but with the flexibility and ease
of programming of a SCPI message based interface. The embedded
microprocessor allows our matrix cards to have extensive Built-in Self
Test, some cards have relay self test with diagnosis down to reed relay
level including switch contact test.
