USB signal generators offer popular bands to 4 GHz

March 27, 2013 // By Graham Prophet
Vaunix Technology, manufacturer of Lab Brick USB powered test equipment, has announced eight new models to their LMS Series of signal generators covering 70-450 MHz, 250-1500 MHz, 600-3200 MHz, and 1000-4000 MHz.

The Lab Brick LMS series of USB-compatible, synthesised signal generators features low noise, fast 100- µsec switching time, and fine 100 Hz frequency resolution, requiring no additional DC supply voltage. Advanced features include phase-continuous linear-frequency sweeping; selectable internal/external 10 MHz reference; optional pulse modulation; ability for GUI software to track and control several connected signal generators, simplifying multiple-signal test setups; and device storage of settings in internal memory, allowing it to power up in a specific instrument state. All devices offer robust aluminum construction.

The new models include: LMS-451D, a 70-450 MHz unit with +10, +13, and +20 dBm output power options; LMS-152D, a 250-1500 MHz unit with +10, +13, and +20 dBm output power options; LMS-322D, a 600-3200 MHz unit with +10 dBm output power; and LMS-402D-13, a 1000-4000 MHz unit with +13 dBm output power. Applications for these products include building automated test equipment (ATE), use as a portable LO source, and engineering/production test lab use, both stationery and mobile.
