Review on 🔬 Advanced Semiconductor Analyzer with Curve Tracing - PEAK Atlas IT (DCA Pro) by Brandon Miller

I bought this item in 2016 - I use it a lot for my tube amp, guitar effects - repairs, rebuilds and custom builds. I needed something to handle all the semiconductors in different guitar amps and pedals - from diodes (silicon, germanium, shock, zenar, LEDs etc.) - transistors (new, vintage, silicon, germanium, signal, power etc.) ) and FET, JFET, MOSFETS and other devices you may encounter while working with this device. I needed a robust, easy-to-use analyzer for testing, as well as advanced features that would allow me to evaluate and sort through parameters such as gain (hFe) - create trace curves with memory for matching and the ability to " yes /no" Fast sorting of potentially hundreds of devices that need to be sorted by a specific parameter value. This analyzer does all this and more, with a simple computer interface that further enhances its advanced built-in features/functions. I was concerned about the price (expensive at the time), reliability, sturdiness given the small size and thin appearance, and the lack of a connector/transformer for the external battery rectifier? Well all of those fears have been washed away after receiving and using this device for the past 4 years (same battery btw). There's 'price' and 'cost' - too many just focus on price - this analyzer is worth every penny considering it does what no other in its price range does - and to me not just convenience, but also It also turns out that there is a need to save time and have a device that you can rely on to work whenever you need it, and exactly - sorting and curve following has become one A necessity when you need to sort through hundreds of transistors to create matching parameters - a fuzz or pedal boost that not only works, but sounds better than the rest. So DCA75PRO = HIGHLY RECOMMENDED Not so - ESR70 and LCR45 are great analyzers too, but for around $140 and $120 a pair - you can buy (again after a few weeks of research) the DE5000 LCR meter/analyzer - does it all what they do these 2 meters and even more. and only costs $118 for a kit with additional probes. For an additional $14 and $20, you can purchase upgraded 1m alligator test leads with a large Kelvin cable clamp to replace the 3" test leads that come with the DE5000 TL-21 Kelvin Test LEAd interface connector. Luckily the TL-21 test leads come with the meter and can easily be opened up (2 screws on the back) to desolder the short leads and solder on the 1m Kelvin test leads after the BNC connectors on these new ones test leads have been disconnected). The Revain page for the DE5000 has the correct results for the Kelvin test, which I mention here on the same page as the recommended "commonly purchased" item. This meter has laboratory accuracy, can measure inductance, capacitance (along with all other capacitor parameters including phase angle, ESR, "Q" etc.), resistance (AC impedance and DC resistance) - the LCR function can be set for circuit measurements . (serial or parallel connection) and what makes it different from all the others is the ability to set the frequency of the test signal in the ranges: 100 Hz, 120 Hz, 1 kHz, 10 kHz and 100 kHz. No other LCR that I know of can test these 5 different and important areas. This is especially important when designing audio circuits and power supply filters, where frequency is important when choosing the right capacitor or inductor, as their values will change depending on the AC frequency at which they are designed to operate. Of course, ESR measurement is important for capacitors working in specific circuits. where a high ESR can adversely affect the operation of the circuit. I've been using the DE-5000 for 4 years and no doubt it's my capacitance, inductance and complex impedance meter or for circuit resistance measurements where my DMM isn't giving me correct measurements. The only thing this analyzer can't do (and none of the battery powered ones including the Atlas can) is leak test capacitors at nominal voltage - like e.g. B. a 100uF/500V power supply capacitor in a tube amp. To do this I need to get my old Heathkit IT-11 which tests capacitors up to 600 volts by applying up to 600 volts across the capacitor to measure leakage. This BTW can be very dangerous for a beginner and I don't recommend messing around with high voltage capacitors unless you are familiar with the dangers and understand the technology (e.g. how capacitors KEEP those high voltage charges even after power is removed) . They can still kill you after removing power from the HK IT-11. So Peak Atlas ESR and LCR Analyzers - Excellent Quality - YES, excellent value for money?ESR and more at more user-configurable test frequencies than anyone Atlas devices with equal or better accuracy/accuracy and more functionality than the other two, combined with the best range - lower and upper limit in relation to the component test ranges Peak Atlas DCA75 PRO - Absolutely the best on the market - Excellent quality - YES, good Value for money - YES
