Telemetry Transmitter for FM with up to 3 Bands
LS-11-F
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.

LS-45-DB
The Lumistar LS-45-DB Dual Channel Bit Synchronizer Daughterboard provides optimal reconstruction of a serial PCM data stream that has been corrupted by noise, phase jitter, amplitude modulation, or base line variations. The all-digitaldesign assures a high performance, consistent product, with excellent reliability and long-term stability. Dual channel design can feed each channel of the LS-55-DD dual decom. The LS-45-DB also has a post D combiner that allows for optimal ratiocombining of the two input signals A unique Built-in-Test feature allows performance verification for the Bit Synchronizer to ensure the highest level of operation. Auto-test BIT is performed for a short duration on the application of power and tests more than 90% of the Bit Synchronizer components. This test verifies that power is properly applied, verifies that there are no internal bit errors, and performs other tests to ensure that the bit synchronizer is fully operational with status indication of results. Command-test BIT performs the same functions and can be initiated by the user at any time through the Lumistar software when used on Lumistar PC products. The user has the ability to generate internal pseudo-random patterns and calculate internal bit error rates with or without the injection of forced errors.Various status indicators are also available through the software. The Bit Synchronizer also contains a BER reader as well as frame sync pattern indicator.

Displacement Transducers
Procter & Chester Measurements Ltd
Pressure: Measures gas or liquid pressure. Pressure is an expression of the force required to stop a fluid from expanding. The transducer generates a signal from the pressure imposed upon it. Torque: Measures the torque (or twisting motion) on a static or rotating system. The static torque element has little movement and therefore more economic to manufacture and purchase. Rotary or dynamic torque is more complicated as the signal needs to be transferred using slip rings, wireless telemetry or rotary transformers/inductance technology so that the strain gauged shaft can continuously rotate. Displacement: Measures distance. The displacement transducers that PCM offer are slightly different to standard units. They have a strain gauge/wheatstone bridge. The benefit here is that if the customer has existing electronics that uses strain gauge/load cell technology, they can use them with these sensors.

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.
