In this episode Shahriar takes a close look at the Signal Hound Real-Time Spectrum Analyzer (BB60C) and Tracking Generator (USB-TG124A). In order to evaluate the performance of these units a few experiments have been setup. The performance of the Signal Hound unit is compared with the Tektronix RSA306.
A set of FHSS 900MHz long-range radios are used in the first experiment. The frequency hopping behavior, channelization, bandwidth and transmit powers are all captured using the BB60C. Furthermore, the recording capability and zero-span modes are used for frequency demodulation. The tracking generator (USB-124A) is then used to measure the performance of a band-pass microwave filter as well as a high-gain amplifier (40dB) gain. The free-space performance of the TekBox EMC Probe Set is also measured using the tracking generator.
