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.

The Model FIM-71 is a portable, laboratory quality Field Strength Meter designed for rigorous field applications. Combining a calibrated half-wave dipole antenna and a highly accurate tuned voltmeter with a range of 140 dB, the FIM-71 is suitable for practically all types of RF emission measurements in the 45 MHz to 225 MHz spectrum. The operator can switch select wide or narrow bandwidth, peak or average value of TV or pulse modulated signals, AM or FM demodulation, and a meter dynamic range of either 20 dB or 60 dB. A dc analog output voltage, proportional to the meter indication, is provided for driving a chart recorder. A leveled output from the calibrating oscillator is available for measuring cable insertion loss, filter response, amplifier gain, and other signal ratio measurements. The 4-1/2 inch, taut band, mirrored scale meter is calibrated in volts and dB for precise measurements in field or laboratory environments.

Class A Ovens
-
Gruenberg ovens can be designed as Class A ovens to conform to OSHA, NFPA 86A, Factory Mutual (FM) and Factory Insurance Association (FIA) requirements. Class A ovens are equipped with a high exhaust rate: because the heating elements are an ignition source so a high exhaust rate is needed to dilute the volatile vapors below the “lower explosive limits.” As a result, the heating elements’ kW must be sufficiently increased to compensate for the heat loss caused by the above-normal exhaust rate. In addition, for a Class A oven to be energy efficient, the additional kW required must be carefully calculated according to solvent load and operating temperature requirements.

Wide Mechanical Tuning Bandwidth Gunn Oscillators
-
Wide mechanical tuning bandwidth Gunn oscillators utilize high performance GaAs Gunn diodes and various cavity designs to yield near full band frequency coverage. Unlike dual-tuner oscillators, frequency and power optimization are accomplished by a single micrometer. Furthermore, these oscillators can be modified into electrically tunable oscillators by replacing the micrometer with an electrical actuator. The wide tuning bandwidth of these oscillators offers a low cost, high performance means of signal generation, making them ideal test sources for labs and antenna ranges. While standard models offer a waveguide interface, a coaxial interface is also available. When used with a Gunn oscillator regulator/modulator (SOR series), these oscillators can produce AM or FM modulated signals for many test applications.
