The LT3955, a DC/DC converter designed to operate as a constant-current source and constant-voltage regulator with an internal 3.5A switch, is now available from Linear Technology. The device’s internal PWM dimming generator makes it ideal for driving high current LEDs, and it also has features suitable for charging batteries and supercapacitors.
Aeroflex Inc. announced the addition of enhanced VSWR (return loss) and distance to fault to the tracking generator functionality of the Aeroflex 3550 Digital Radio Test System. By utilizing the sweep of the tracking generator, the 3550 can measure and display the VSWR of an antenna or find the location of one or more faults in a cable.
Anritsu Co. will be exhibiting the new P25 Phase 2 TDMA analysis capability of its S412E LMR Master, as part of its portfolio of test solutions to address the key technologies associated with public safety networks – including LTE, narrowband and P25 – during IWCE 2013 in Las Vegas, March 11-15.
NuWaves Engineering, an international Radio Frequency (RF) and Embedded Systems solutions provider, announced that two of its module-level RF products, the Multi-Octave RF Upconverter (MORF™) and the ConvertaWave2™ Downconverter, have been selected by ViaSat Inc. to be embedded in the company’s VRG-1000 RF Signal Environment Generator product line.
The MS2720T features a touchscreen, full-band tracking generators to 20 GHz, and best-in-class performance for dynamic range, DANL, phase noise, and sweep speed, providing unprecedented levels of spectrum monitoring, hidden signal detection, RF/microwave measurements, and testing of microwave backhauls and cellular signals.
Agilent Technologies Inc. announced a new basic spectrum analyzer for budget-constrained applications in R&D, manufacturing, maintenance, educationlabs, spectrum management, benchrepair and other general-purpose analyzer applications.
Teseq Inc., a leading developer and provider of instrumentation and systems for EMC emission and immunity testing, now offers a pulse generator with improved accuracy. The FT 5531, an upgraded version of the FT 5530, supports classic and modern testing standards.
Rohde & Schwarz now offers harmonic filter options for its R&S SMB100A microwave signal generator. These filters make it possible to achieve a harmonic suppression of more than –50 dBc over a wide frequency range from 150 MHz to max. 40 GHz. At low frequencies below 3 GHz, it is even possible to achieve an excellent –58 dBc.
Rohde & Schwarz has enhanced its fully integrated R&S SGS100A by adding a model for I/Q modulated signals from 80 MHz to 12.75 GHz. Combined with an I/Q baseband generator, the instrument can be used to generate test signals for all radio standards in this frequency range. As a result, the R&S SGS100A is ideal for X-band signals from 8 GHz to 12 GHz for radar and satellite communications. The I/Q modulator's wide RF bandwidth of 1 GHz makes it possible to generate pulses with high chirp bandwidths and steep pulse edges.
Agilent Technologies Inc. announced that its Signal Studio for Global Navigation Satellite Systems (GNSS) software (N7609B) has been enhanced with real-time and basic mode capabilities designed to allow engineers to simulate Galileo signals for receiver testing and to address the needs of the manufacturing test market.
