90332 -
HITEC Sensor Solutions Inc.
The 90332 digital FM telemetry systems is designed to be used with full-bridge, strain gage sensors. The system features a miniature transmitter powered by a simple 9V battery, and a remote receiver capability of receiving the digital transmission over long distances. The digital technique eliminates many of the problems associated with traditional analog frequency modulated telemetry systems. Improvements with a digital technique include elimination of ripple, temperature drift characteristics, and higher signal resolution.

Model 514 -
Inovonics Inc.
Inovonics’ INOmini 514 is a standalone decoder for FM-stereo multiplex signals. It accepts a demodulated FM-baseband input and decodes the signal to discrete left and right channel audio. The recovered stereo program is available as a professional line-level balanced output, and also as an AES digital audio signal.

MS 1522 -
Meltronics Systemtech
Transmitter and Receiver units are designed to work at 24V DC voltage (nominal) with variation between 19.2 V to 28.8V. The system is designed to work with carrier frequency 1800/2700 Hz and modulated frequency 65Hz/85Hz. For 1800Hz Carrier Frequency RED border is used in Front Panel and for 2700Hz Carrier Frequency BLUE border is used in Front Panel. Maximum power consumed by transmitter and receiver are 1.2W and 8W, respectively. Sense level for receiver is less than –19 dBm and No sense level for receiver is more than –22 dBm with 1mw (0 dBm) transmitter power. The equipment is designed to work satisfactorily with temperature variation from 0°C to 55°C with relative humidity of 95% at 35°C. Suitable test points are provided in the back of the equipment to monitor the necessary parameters.

Si4703 -
SparkFun Electronics
This breakout for the Silicon Laboratories Si4703 FM tuner chip is a little more stripped down than our FM Tuner Evaluation Board. If your project already has an amp and just needs a full-featured FM tuner, this is the board for you. Beyond being a simple FM radio, the Si4703 is also capable of detecting and processing both Radio Data Service (RDS) and Radio Broadcast Data Service (RBDS) information. The Si4703 even does a very good job of filtering and carrier detection. It also enables data such as the station ID and song name to be displayed to the user.

LS-11-F -
Lumistar Inc.
The LS-11-F portable FM test transmitter is designed for checkout and troubleshooting of telemetry receiving systems operating with FM modulation. For applications with any of the ARTM modulations (Tier 0, Tier I, or Tier II), please refer to the LS-11-M Data Sheet. Complete ground stations including the antenna with LNA, RF down-converter, IF receiver, bit synchronizer, and PCM decommutator can be tested and bit error tests performed. The design allows secure links to be tested with an external encryptor. The Test Transmitter contains an internal PCM Data Simulator and Pseudorandom patterngenerator that operates in a BERT mode. The device provides simulated clock and data (without transmitter enabled) and accepts external data for modulating the internal transmitter. Complete setup can be achieved locally through the keypad and two-line LCD display or remotely through the USB Interface. Operational parameters include the PCM format parameter database information (frame sync patterns, wavewords, etc…), pre-modulation filter selection, transmitter carrier frequency, transmitter deviation, and output power level. Output power can be selected from approx. -60 to +5 dBm in 5 dB steps. The Test Transmitter contains a LiFePO4 Battery (Lithium Iron Phosphate), which provides higher energy density at ¼ the weight of legacy lead-acid batteries. The unit also provides an internal battery charger and will operate for up to twelve hours on battery power having received on a full charge.

Cen-Stat Static Grounding Clamps -
Newson Gale Inc.
Static grounding systems like the Earth-Rite range combine interlock control and visual indication to verified ground connection points and offer the highest levels of protection over electrostatic ignition risks. However, equipment specifiers may select passive grounding devices, like single pole clamps, to ground and bond plant equipment.

LS-27-B -
Lumistar Inc.
The Lumistar LS-27-B Modular Dual Channel Tri-Band Tracking and Data Receiver is Lumistar’s third generation of modular high performance FM Receivers. This wideband designs supports one or two independent channels of PCM with data rates up to 20Mbps. The unit includes both an optional FM demodulated output for PCM data, and standard programmable AM/linear AGC outputs for auto-tracking receivers. The design offers 8 IF Bandwidths and 8 Video Filters per channel for each receiver.AC coupling with a low pass filter is employed to ensure a high quality data link with long strings of NRZ-L ones or zeroes. The unit provides a software selectable 10 MHz reference I/O port forlocking local oscillators to a high precision external source or to arrange multiple units in a master/slave arrangement. The receiver’s control and status is achieved via Ethernet, USB or auto-switched RS-232 (or “4-wire” RS-485 in place of 232). When utilizing the RS-422 interface, multi-drop configurations can be accommodated.
