Billed as an alternative to large, expensive signal generators, the NovaSource G6 RF signal sources cover frequency bands ranging from 2.4 to 5.875 GHz. The instruments provide coverage for emerging license-free ISM bands with wireless product standards, such as 802.11a, 802.11b and Bluetooth, as well as other bands populated by U-NII, HiperLAN, and wireless local loop users. Though designed for use on the lab bench, the G6Õs compact sizeÑabout the size of an ordinary walletÑmakes it well suited for field applications. The instrument has a simple user-interface and non-volatile memory and has the ability to perform internal frequency modulation, making it suitable for new PCS and cellular development and test applications. In addition, the instrument includes an entirely new frequency sweep function, which is said to be a useful tool for applications such as filter testing and birdie searches. A standard serial interface replaces the parallel interface found on other NovaSource family products. Users can choose from six frequency bands: 2.4 to 2.9 GHz, 3.4 to 3.7 GHz, 3.7 to 4.2 GHz, 5.15 to 5.35 GHz, and 5.47 to 5.875 GHz. Step sizes as small as 1 kHz are standard. Price is $899 each for quantities fewer than 10. For more details, call Dave Jordan at NOVA ENGINEERING INC., Cincinnati, OH. (800) 341-6682.
