Common HAM and Broadcast uses for a spectrum analyser

1. Measuring the performance of a crystal filterHams use crystal filters in their radios to enhance selectivity, but short of installing thefilter there is really no easy way to test one. A spectrum analyser with a tracking generatormakes it fairly easy. Simply feed the tracking generator into the filter input and look at theresulting response from the filter output.A nice additional feature on so...

Is the DSA-815 CISPR Compliant?

The Rigol DSA-815 Spectrum Analyser represents a significant shift in how companies perform EMI and EMC testing. Now, R&D Engineers can afford to have test equipment that allows them to troubleshoot and test designs on their bench without having to schedule and pay for time at a full compliance lab. As with any product, there are trade-offs for cost vs. performance. The DSA-815 is a great too...

Hints for optimizing Demodulation with a Spectrum Analyser

The Rigol DSA1000 and DSA800 series spectrum analysers have demodulation capabilities.Here are some hints that can optimize the demodulation output.1. Use an antenna matched for the frequencies of interest2. Set the center frequency of the spectrum analyser to the center frequency of the signal of interest. For example, of you wish to demodulate an FM signal with a carrier of 100MHz, set your spec...

Spectrum Analyser Feature Demonstration

The DSA 800 series of spectrum analysers are packed with features. Spectrum analysers are similar to oscilloscopes.. except that they measure and display amplitude vs. frequency and not amplitude vs. time as a scope does. Typical applications include Radio (Channel monitoring, demodulation of radio transmissions), Characterizing antennas, amplifiers, and filters, EMI/Interference testing, and RF...

Is a Preamp necessary with EMI work?

It's generally recommended to use a preamp with a spectrum analyser when performing EMI and EMC pre compliance tests. The preamp is used to amplify the acquired signal above the noise floor for low level signals. So it's very useful for EMI work. Final determination will come down to what energy levels will be tested....
