Average detector

Posted on: December 16th, 2020 by Doug Lovell

16/12/2020
The RIGOL DSA800 and DSA700 families have an RMS Average detector which is great for basic average measurements. However, the RMS Average detector differs from the Linear Average detectors associated with many EMI measurements.This measurement can best be approximated by combining a video bandwidth filter of 10 Hz and us...

16/12/2020
AMK-DSA800 option provides various measurement functions, including T-Power (Total Power), ACP (Adjacent Channel Power), Chan Pwr (Channel Power), OBW (Occupied Bandwidth), EBW (Emission Bandwidth), C/N Ratio, Harmo Dist (Harmonic Distortion) and TOI (Third Order Intermodulation). For advanced measurement functions, the measurement mode can be single or continuous and you can control the measureme...

Why am I seeing the message “Intermediate Frequency Out of Range”?

Posted on: December 16th, 2020 by Doug Lovell

16/12/2020
There is too much power being delivered to the instrument.The Spectrum Analyser is a Swept Superheterodyne design and does not have preselection filters. Therefore, the mixer is seeing all of the power (full 9kHz-1.5GHz frequency range) regardless of what you have set for the start and stop values....

Setting up the DSA800 series spectrum analyzers to capture the lowest level signals

Posted on: December 16th, 2020 by Doug Lovell

16/12/2020
The DSA800 series spectrum analyzers consist of the DSA815, DSA832E, DSA832 and DSA875. Each can come with or without a tracking generator.The lowest level signal you will be able to see captured on a spectrum analyzer will be limited by the DANL or displayed average noise level so the lower the DANL the better....

16/12/2020
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 gen...
