An alternative to Commercial Off The Shelf systems, Mnemonics' presents their newest development.

Mnemonics, Inc. has developed and fielded IBS receive and processing systems since early 1984. The Miniature Integrated Broadcast System (MIBS) Part number ZS4001C, technology is a small ¼ ATR "FAT" design that is light weight and offers an open systems compliant design. MIBS integrates proven technology that lowers risk, and will be fully sustainable in years to come.

We have incorporated a cost effective spiral development plan for future growth supporting the possible addition of alternate configurations. These configurations can support transmit and receive functions as well as providing the necessary pathway for the cryptographic requirements supporting the Common Integrated Broadcast (CIB).

MIBS

Based upon the Mnemonics certified Zebra cryptographic module, the certified Wedgetail BI Terminal software, a commercial off-the-shelf (COTS) processor, and the latest in miniature software defined receiver technology, the Mnemonics IBS receiver provides all the receiver capabilities in small light weight, reconfigurable package. The ¼ ATR chassis is 2.6 x 7.62 x 16.25 inches. The total weight is less than 15 lbs.

Radio Technology

The MIBS radio technology was adapted from the Software Defined Radio Architecture. The system allows for the ability to use programmable RF filters, synthesizers, and modems. The use of standard 6 U VME symmetrical mother board assists in maintaining a common configuration. With the use of a Mnemonics developed Quad-Channel SATCOM receiver mezzanine we are able to package the system in a small cool operating form factor. This common form factor allows the insertion of a full band transmitter mezzanine if desired.

The Acu-Trac® NEMA6 liquid level transmitter is a non-contact transmitter that is a direct replacement for level senders on tanks with depths up to ≤ 3.0 meters (118 inches). The NEMA6 liquid level transmitter offers a choice of outputs (analog current loop; ratiometric voltage; or non-ratiometric voltage).

The NEMA6's RS-485 bus allows real time processing of fuel data and messaging over the RS-485 bus.

The RS-485 bus also provides the user flexibility to program the NEMA6 liquid level transmitter for tank configuration, digital filtering, transmitter mounting offset, gauge drive output full and empty endpoints and communication mode.

• KYNAR® Package: Chemically resistant Polyvinylidene Fluoride (PVDF) package.

• More Accurate: 2% of tank volume

• More Reliable: Acu-Trac® NEMA6 liquid level transmitter is non-contacting. Resistive float sender have a wiper that slides across a resistive strip that with time can wear and cause intermittent or complete loss of the signal.

• Non-Invasive: Acu-Trac® NEMA6 liquid level transmitter mounts to the same opening as the resistive float sender, but does not protrude into the tank.

• Digital Filtering: User programmable time constant in digital filtering eliminates errors due to fluids sloshing in mobile tanks.

• Tank Profiling: User programmable strapping tables for unique tank shapes.

• Chemical compatibility: Acu-Trac® NEMA6 liquid level transmitter works with a wide variety of media including diesel, motor oil, hydraulic fluid and black water.

• Self Test/Diagnostics: Power Up Test verifies liquid level transmitter is operating properly and diagnostic messages are sent over the RS-485 bus.

• Real Time Fuel Data: Real time fuel data over the J1708 data link for on vehicle communication.

• RS-485 Messaging: Three types of messages are provided on the RS-485 bus – setup and programming commands, timed data broadcast message, and diagnostic messages.

• NEMA 6 Rating

• CE Mark Class B Rating

New battery-powered microminiature RF wireless instrumentation system measures and transmits up to 64 channels of programmable temperature data to a PC.

Endevco Corporation's new Model 5860 MicroWIS RF wireless data acquisition network measures and transmits temperature data via a wireless link to a receiver plugged into the RS-232 port of a personal computer (PC). Up to 32 Model 5010 wireless temperature transmitter units can be placed within the coverage zone to collect temperature data at programmable sample rates varying from 1 sample-per-second to 1 sample-per-hour. This system can be used in a broad range of test and monitoring applications, including aerospace, automotive testing, laboratory, process industry, and manufacturing.

Operating in the license-free ISM band, the network provides reliable RF communication up to 100 feet indoor (No LOS) and 200 feet outdoor (LOS). The transmitter units are designed for applications that operate at low power (7 mA in active mode and <2 microA in standby mode). This provides for a battery life up to one year at a 1 sample-per-minute rate.

Each transmitter unit has two input channels for sensing two temperatures: one internal and one external to the unit. The external temperature (-200°C to +200°C) is measured via a two-wire Resistive Temperature Device (RTD). Temperature data in digital format is encoded with the Unit ID and error detection code, packetized and transmitted.

The Model 5860 receiver unit is plugged into a PC through the serial port and collects the data from all transmitter units. This data is plotted and logged on the PC. Standard Windows 95 and Windows 98 user interface software accepts user setup commands and then broadcasts them to the transmitter units. When data from the transmitter unit is received, the application software time stamps the data. The complete MicroWISÔ Microminiature Wireless Instrumentation System is typically installed and configured in less than an hour.

Endevco is the world's leading designer and manufacturer of dynamic instrumentation for vibration, shock and pressure measurements.

The MS2721B handheld spectrum analyzer is designed to conduct highly accurate analysis on the new wave of wireless LAN and cellular signals, including 802.11a, 3G, ultra-wideband, WiMAX, and wireless medical patient monitoring systems. The MS2721B is ideal for AM and FM broadcast proofing because the wide dynamic range and low phase noise make NRSC measurements on analog and IBOC signals easy with no need for an external carrier notch filter. The MS2721B is a small and easy to use portable spectrum analyzer with unprecedented measurement capability for applications up to 7.1 GHz. Weighing in at less than 7 pounds, it is equally at home on the engineering bench and in the field.

Other members of the B series family include the MS2723B that covers up to 13 GHz and the MS2724B that covers up to 20 GHz.

Options for this instrument enable the user to add WCDMA, GSM, GPRS, EDGE, and HSDPA measurement. Options for measuring and demodulating fixed WiMAX signals are available. The tracking generator option delivers specified performance from 400 kHz to 7.1 GHz. A GPS receiver can be added to allow measurements to location-stamped and to greatly improve time base accuracy.

Another option adds spectrogram, signal strength and RSSI. There is an option to add a user definable channel scanner option that is excellent for interference mitigation work in complicated RF environments.

Several smart measurements are built into the MS2721B, including channel power, adjacent channel power ratio, Carrier to Interference ratio (C/I), and field strength. In addition, an AM/FM/SSB demodulator is included. Demodulated signals can be monitored using the internal speaker or by using a universal 2.5 mm 3-wire headset, such as used with many cellular telephones.

The MS2721B spectrum analyzer has low phase noise of -100 dBc/Hz @ 10 kHz offsets, best in its class typical DANL of -163 dBm in a 1 Hz RBW, resolution bandwidth (RBW) range of 1 Hz to 3 MHz and video bandwidth (VBW) range of 1 Hz to 3 MHz. It also has the fastest sweep speeds of any spectrum analyzer in its class. It automatically sets the fastes possible sweep speed consistant with accuracte measurement results.

The use of Compact Flash memory modules or USB Flash Drives up to 512 MB allows an unlimited number of traces and setups to be stored. Measurements may be stored directly to the compact flash module or the USB Flash drive. A 512 MB module will hold over 20,000 Spectrum Analyzer measurements. Remote programming using the Ethernet 10/100 Base-T connection is provided using SCPI programming. The Ethernet connection gives the user flexibility in remotely operating the instrument using Anritsu's remote access software, shipped with the product. Measurements and setups may be uploaded and downloaded using either the Ethernet or the USB connection.
