In this episode Shahriar attempts to repair an HP 8648C Synthesized Signal Generator from a dumpster dive. The cause of failure is investigated and traced. Alongside the repair efforts, the internal construction and components of the synthesizer are also presented. Various component teardowns are shown and described including the structure of the VCO used in the generator assembly. The functionality of the repaired unit is verified using an Agilent Power Meter and Rigol Spectrum Analyzer. Finally, the overall unit block diagram is presented and the principle of operation is described in detail.
In this episode Shahriar presents the teardown of an Advantest TQ8325 Wavelength Meter. The principle operation of the instrument is explained along with a close up of the free space optics in operation. To verify the functionality of the unit, an infrared laser module is used as a CW coherent source. The impact of the laser diode’s temperature variation on the output wavelength is measured using the wavelength meter.
I’d like to Acknowledge Dr. Jeffery Lee for his consult and expertise on free space optics and fiber optic measurement systems.
In this episode Shahriar investigates the cause of failure of an E3634A DC Power Supply. The video features a step by step troubleshooting and teardown of the damaged power supply. Various schematics and block diagram of the power supply are presented. Will he be able to fix it?
In this episode Shahriar takes a look inside the “Logic”, “Logic16″ and USBee SX which were reviewed in the previous episode.
