TPI USB Wideband Signal Generator

TPI Wideband Signal Generator & Computer Display - RF Cafe Website

Robert Yarbrough, an independent consulting RF engineer, sent me information on a nice compact, inexpensive, wideband RF signal generator that he has developed. Joining what has become a very extensive array of USB-powered test instruments - signal generators, power meters, oscilloscopes, multimeters, spectrum analyzers, software defined radios, etc. - from various vendors, the TPI Synthesizer generates high spectral purity signals ranging from 35 MHz to 4.4 GHz with programmable output power levels from -55 to +10 dBm. Sweeping can be set for both frequency and power for testing both frequency and amplitude responses of passive and active devices. The unit can be locked to a 10 MHz external reference and it also has a buffered 10 MHz output for locking other devices to the synthesizer. Executable user interface software runs under Windows, and was developed for LabView and Tickle platforms. At a price of only $330, this synthesizer is well within the budgets of many experimenters and hobbyists, and can supplement the research and development laboratory equipment of professional and academic institutions. Extensive hardware and software descriptions are available on the TPI Wideband Signal Generator website.

For amateur radio enthusiasts, Morse Code and beacon software modules are available.

I get quite a few requests for consultant referrals. If you are in need of assistance, you might consider talking to Robert.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived...
