![]() ![]() I've decided that the only hope for this thing is to try and align the front end (which btw Pioneer recommended be replaced if there were any issues). It needed to be totally disassembled, cleaned, and lubed before any alignment attempt.Īt any rate, back to our story. The manual's alignment instructions specifically state that attempting to align the front end may "prove unrecoverable" or something to that effect. Specifically in this case a Pioneer SX-1980. The immediate need is FM tuner front ends that have been worked on by, shall we say, the unqualified. ![]() It's time for something that I can lift with three fingers. I've got a bench full of older HP gear for this, anchored (literally) by a 141T SA system with tracking generator. I have decided (probably) that its time to step up to the world of digital spectrum analyzers with a side of oscilloscope, and possibly even self contained sweep generator.Ī bit of background. 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.Greetings to all. 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 100 Hz. Benefits of Rigol's all digital IF design 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. 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. The use of digital IF (intermediate frequency) technology guarantees reliability and performance to meet the most demanding RF applications. The Rigol DSA815/TG is a compact and light Spectrum Analyzer with premium performance for portable applications. ![]()
