Synchro/resolver measurement on a VME
card
ACAL Microsystems has introduced the North Atlantic Industries 64CS3 - a high-density, DSP-based VME card.
ACAL Microsystems has introduced the North Atlantic Industries 64CS3, a high-density, DSP-based VME card that includes eight separate, transformer isolated synchro/resolver to digital channels and six separate, transformer isolated digital to synchro/resolver convertor channels Each channel has a 16bit resolution (24 bits for combined two speed operations), accurate digital velocity outputs (user programmable for single-speed and two-speed modes), wrap-around self-test, and an optional 5V A programmable reference supply

Embedded controller allows direct access to ATM
The Interphase 4531, available in the UK from Crellon Microsystems, allows system integrators to access the ATM backbone without requiring an external CSU/DSU.
Embedded motherboard configured for connectivity
The PATX3070 Pentium-class motherboard, now available from Crellon Microsystems, combines AGP graphics capability with a range of powerful interfaces.
One outstanding feature of this card is the continuous background built-in-test (BIT), which is totally transparent to the user and is performed on all functions and channels, including accuracy tests in addition to reference and signal loss detection.
The BIT requires no programming, and does not interfere with the normal operation of the card.
Power-on self test, however, can be user programmed.
Measurement channels feature an accuracy of 1 arc-minute and simulation channels an accuracy of 30 arc-seconds.
All channels can produce as an option, differential incremental encoder (A and B) outputs, with programmable resolution, and either a zero degree marker pulse or commutation outputs for 4, 6 or 8 pole brushless DC motors eliminating the need for Hall Effect sensors on the motor.
Even encountering large accelerations, the S/D channels do not loose tracking because they shift to higher bandwidths smoothly, continuously and automatically with no glitches with tracking rates being limited only by bandwidth restrictions up to 150rps at 16bit resolution This card is available in both commercial and military temperature ranges, and is ideally suited for programs, including airborne, shipboard, ground mobile and C3I applications.
The 64CS3 is available with operating temperature ranges of -40 to +85C and 0 to +70C.
Conduction cooled versions with wedgelocks are also available.
