Precision Voltage and Current Sources
VI-700
-
The VI-700 Voltage and Current Source is a versatile precision dialable or remotely programmable voltage and current source. Its three ranges provide up to 20 V full scale (200 V with the HV option), and down to 100 mV resolution; and 20 mA full scale down to 0.1mA resolution. Both voltage and current outputs are available simultaneously. The output is set by a range selector and thumbwheel switches in the LOCAL mode, or by a digital input at the rear panel. The REMOTE mode control can be a RS232 or IEEE-488 interface.

Serializer/Deserializers & Selector Muxes
-
Serializer/Deserializer muxes use both rising and falling edges of the clock to serialize the data from parallel inputs to serial output while demuxes deserialize the data from its serial input to parallel outputs. Selector muxes routes the differential inputs to either one or more of the desired outputs upon assertion of the appropriately selected port. Muxes can be used in various applications including High Data Rate Ethernet, Fiber Communication, Signal Routing and Broadband Test & Measurement Equipment.

Standard Directional Gyroscopes
4000B-series
-
The 4000B is our standard air-driven directional gyro. As the aircraft turns left or right, gears on the sensing unit and dial shaft translate this rotation into rotation of the instrument’s vertical dial. Left turns produce clockwise dial rotation and right turns produce counter-clockwise rotation. The gyro is controlled by a heading selector knob located on the lower left of the instrument. Pressing and turning the knob first disengages the dial shaft and then resets the dial to a new heading, which results in a new course indication. Releasing the selector knob re-engages the dial shaft. The on-course position of the pointer is always at the top of the azimuth circle (0° on the dial with the aircraft headed north).

16 or 32 channel Digital to Analog Converter
LS-71-P
-
The LS-71P PCI D/A Converter (DAC) board provides high speed analog outputs of PCM decommutated data allowing real time data displays using strip chart recorders or similar devices. The LS-71-P board is designed to be used in conjunction with the Lumistar LS-50-P Multifunction PCM Decommutator boards and uses an over-the-top communication bus directly from the decom to the DAC to avoid any glitches in the analog outputs due to PCI bus activity. Direct “mailbox” type access is also provided to allow the user to send information through the PCI bus to the DACs. The DAC board design allows 2 LS-50-D Multifunction decom boards to be used with a single DAC board allowing tagged data from either data stream to be directed to any DAC channel. An optional LS-71-DB Word Selector Daughterboard allows two additional data streams to be monitored with the ability to select channels from 4 data streams to be displayed on any DAC channel. The design incorporates an extremely large memory (more than 200,000 16-bit words) used as a lookup table allowing linear or non-linear EUconversions with constant delay regardless of the number of polynomial coefficients required. Standard product supports a single decom, however, dual decom support is available as an option.
