| Which Spectrum Analyzer Measures Very Low Frequencies? |

Tiny, what did you end up doing? |

Hey! Just a quick update. I ended up borrowing a LabOne Spectrum Analyzer made by Zurich Instruments from another company. I ended up finding out all sorts of neat things about my circuits that I didn't realize. For instance, the cutoff frequency for a basic rc filter changes when biasing at different voltages such as 5V vs 100V. I didn't realize the ceramic capacitors could change so much. I feel like I'm learning a lot more than I expected. Thanks for the great advice guys! I'm still watching ebay for an HP3562. Hopefully budge and available line up just right one day. |

Have you seen the free "Spectrum Lab" software? https://www.qsl.net/dl4yhf/spectra1.html#download The reason I ask is because many audio cards would qualify as capture devices at low frequencies, especially if coupling capacitors were removed or increased in value. It also runs under Wine on a modern Linux OS (just verified) https://www.qsl.net/dl4yhf/spectra1.html Another similar program is Baudline. |
