FYI, long time not here so I don´t know what the current state of the hack is. You will find the Front-End through the last IF (DSP) active, PIN diodes, and Mixer components (with Manufacturer and P/N) for the the DSA815 with Main Board up to v. You will be able to construct it yourself if needed, as I described it clearly in order of signal flow from SA Input through the Last IF (DSP Input). I didn't provide a schematic or block diagram (I could have) just because I didn't need any except for my personal hand sketches I made while tracing it out.
This architecture is valid for all versions of the DSA815s with the different Main Boards. This describes the IF Frequencies, Mixers, LO Frequencies, the on board LEDs that tell you which LO is currently active, etc. 05 (Boot 01.02 and 01.03), and Newer Units with Main Board 00.07 and above, with Boot 01.04) with notes.

High precision amplitude readings: this technology almost eliminates the errors generated by filter switching, reference level uncertainty, scale distortion, as well as errors produced in the process of switching between logarithmic and linear display of amplitude when using a traditional analog IF design. The ability to distinguish between small signals by frequency: using the IF filter with the smallest bandwidth setting it is possible to make out signals with a frequency difference of only 10 Hz. The ability to measure smaller signals: on the basis of this technology, the IF filter enables smaller bandwidth settings, which greatly reduce the displayed average noise level. The menu navigation is very intuitional in use and all functions and parameters are easy to reach because of the graphical interface.īenefits of Rigol's all digital IF design The Rigol Spectrum Analyzers have a sophisticated and easy to use user interface and offers multiple functions for all tasks.
These functions enable the analyzer to acquire signals and match parameters automatically, instead of the manual process necessary with a traditional analyzer. The very large display (20.3 cm / 8") of the Rigol DSA815 Spectrum Analyzer with a resolution of 800x480pixels provides a very good overview over all its comfortable functions like Auto Tune, Auto Range, Auto Scale and Auto Couple. This version is the base unit and does not include the tracking generator. The use of digital IF (intermediate frequency) technology guarantees reliability and performance to meet the most demanding RF applications.
