SAFETY SUMMARY
System Weight and Handling Restrictions - Depending upon the specific system and configuration, each RPTS100 chassis weighs approximately 30 pounds. The RPTS100 is housed in a ruggedized enclosure designed for carrying, handling and operation by one person. Electrical – The RPTS100 is designed to operate on 12 VDC battery power as well as 115/230 VAC 50/60 Hz, and complies with all U.S. and International safety codes and regulations required for safe operation and use of commercial equipment. Use standard and accepted safety practices with respect to operating commercial electrical equipment at all times to avoid the risk of personal injury or death. EMI/EMC – The RPTS100 complies with all FCC and CE regulations regarding electromagnetic interference and compatibility. There are no personnel hazards or safety issues with respect to EMI/EMC when operating the system. Exposure to Radio Frequency (RF) Signals – The RPTS100 is designed to transmit RF signals from 200 MHz to 5250 MHz at levels of +10 dBm to -70 dBm. These signal levels are well below the minimum safe exposure levels prescribed by both U.S. and International standards. There is a high power (+37 dBm) output option available and, when this option is installed all safety practices and procedures in place at the user location applicable to protection from RF signal exposure at these levels must be followed.

2 – GETTING STARTED
2.1 Description The RPTS100 Telemetry Signal Simulator is a portable ruggedized device designed for pre-mission checkout of a telemetry ground station, as well as basic telemetry receiver functional testing. The simulator provides a user-selectable multi-mode modulator, calibrated single RF output, and an optional embedded Bit Synchronizer and Bit Error Rate Tester (BERT) with pseudo-random PCM code generator. The RPTS100 RF output frequency range is 200-1150 MHz, 1415-1585 MHz, 1650-1850 MHz, 2185-2485 MHz and 4400-5250 MHz. Available modulation formats include PCM/FM, NTSC Composite Video, PM, BPSK, QPSK, IRIG 106-09 Tier I SOQPSK-TG and Tier II Multi-h CPM. The RPTS100 can also be externally modulated with a user-provided signal and test pattern, and also has binary file playback capability for external modulation using pre-recorded mission data. The RPTS100 design consists of a single channel RF Telemetry Test Signal, FPGA-based I/Q modulator an internal 10 MHz reference, and an optional embedded Bit Synchronizer/BERT that includes a pseudo-random code generator. These components are all housed in a small, hand-carried ruggedized battery-operated enclosure designed for operation in support of TM ground stations. The Test Signal Simulator provides a phase-locked RF source and modulator with user-selectable, calibrated RF signal outputs from +10 dBm to -70 dBm in 0.1 dB increments. A high power option is available that extends the RPTS100 output levels to +37 dBm. RPTS100 system set-up, control and status monitoring is provided by a front panel Touch Screen. 2.1.1 Configurations and Options The RPTS100 is produced in several user-specified configurations. Standard hardware features include: Single Band RF Tuning (2185-2485 MHz); +10 to -70 dBm RF output; PCM/FM modulation; External modulation; recorded file playback and operation on both 12 VDC and 115/230 VAC power. Optional features include: an embedded Bit Synchronizer and BERT; 200-1150 MHz, 1415-1585 MHz, 1650-1850 MHz and 4400-5250 MHz RF tuning; PM, BPSK, QPSK, Tier I SOQPSK-TG, Tier II Multi-h CPM and composite video modulation modes; and a +37 dBm High Power RF output. 2.2 Initial Hardware Set-up and Operation The user should read this User’s Guide and become familiar and comfortable with the overall features, options and configuration of the specific RPTS100 system that will be used. Table 2-1 lists and describes the RPTS100 I/O. Figure 2-1 illustrates the RPTS100 I/O of all standard and optional configurations with respect to AC and DC battery power, inputs, outputs and Touch Screen controls. 2.2.1 Operation with AC or DC Power Source The RPTS100 can be operated either using its internal rechargeable 12 VDC batteries, or using an external 115/230 VAC, 50/60 Hz power source. A simple three position EXTERNAL AC IN – OFF – INTERNAL BATTERY System Power switch (Figure 2-1) is provided.
