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...

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....

DSA800 USB file limit

Posted on: December 16th, 2020 by Doug Lovell
16/12/2020
On the DSA800 series with current firmware up to version 1.18 there is a known limit on the number of files that can be shown when viewing a USB stick's content on the instrument front panel.This limit is 50 files or directories. Once this number is reached additional files will not be shown in the file browser. This can...

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....

Setting up the RSA3000 and RSA5000 series spectrum analysers to capture the lowest level signals

Posted on: December 16th, 2020 by Doug Lovell
16/12/2020
The lowest level signal you will be able to see captured on a spectrum analyser will be limited by the DANL or displayed average noise level so the lower the DANL the  better.To obtain the lowest DANL the RSA3000/RSA5000 series analyzers will need to be operating within these parameters and settings:...
