Description
The Lab Brick LSG series of USB-compatible signal generators covers frequencies from 20 MHz to 6 GHz with high output levels and excellent spectral purity. They require no additional DC supply voltage and offer several operating modes, including continuous-wave (CW) and swept-frequency. 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. Lab Brick LSG Signal Generators
Each device comes with a USB flash drive containing the GUI software and digital version of the programming guide, along with a 6-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® 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 LSG 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.
