Telemetry Transmitter for FM with up to 3 Bands
LS-11-F - Lumistar Inc. (Lumistar)
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 pattern
generator 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.
