Description
Lab Brick® LMS Signal Generators series of USB-compatible, synthesized signal generators cover a frequency range from 0.5 MHz – 20 GHz with low noise, fast 100-microsecond switching time, and fine 100 Hz frequency resolution. They require no additional DC supply voltage and offer advanced features such as phase-continuous linear-frequency sweeping, internal/external 10 MHz reference, and optional pulse modulation. GUI software can track and control several connected signal generators, simplifying multiple-signal test setups. Each device stores settings in internal memory, allowing it to power up in a specific instrument state.
Each device comes with a USB flash drive containing the GUI software and digital version of the programming guide, along with a 3-ft. USB cable. It measures 4.90 x 3.14 x 1.59 in. (124 x 80 x 40 mm.) and weighs less than 1 lb. (0.45 kg). In non-USB applications, the Lab Brick® signal generators can operate with battery power or remote power supply. For automatic-test-equipment (ATE) applications, a programming guide is available for each Lab Brick® signal generator. In addition, they are programmable by means of LabVIEW software drivers from National Instruments (www.ni.com). Lab Brick® LMS Signal Generators
Lab Brick® synthesized signal generators comply with international requirements for electromagnetic-compatibility (EMC) emissions and immunity for Class A ISM devices to ensure that they don’t interfere with other ISM-band equipment. All Lab Brick LMS signal generators are ROHS-compliant and can be used with any PC or laptop computer with USB 2.0 port (or powered USB hub) and Windows 2000, XP, Vista, or Windows 7 operating system.
