The DCA Pro is an advanced new design that features a graphics display, USB communications, PC Software and an enhanced component identification library. The DCA Pro supports all the components that the popular Peak Atlas DCA55 supports, but adds plenty more. Components supported include: 1. Transistors (including Darlingtons and "digital" transistors), Silicon and Germanium types. Measures gain, VBE and leakage. 2. MOSFETs, enhancement mode and depletion mode types. Measure on-threshold (at 5mA) and approx transconductance (for span of 3mA-5mA). 3. JFETs, including normally off SiC types. Measures pinch-off voltage (at 1uA) and approx transconductance (for span of 3mA-5mA). 4. IGBTs (insulated gate bipolar transistors). Measures on-threshold (at 5mA). Diodes and Diode networks. 5. LEDs and bicolour LEDs (2 lead and 3 lead types). 6. Zener Diodes with measurement of zener voltage up to 9V at 5mA. 7. Voltage regulators (measures regulation voltage less than 8V, drop-out voltage, quiescent current). Note that some regulators are not stable without their decoupling caps and/or minimum load and cannot be tested by the DCA75. 8. Triacs and Thyristors that require less than 10mA of gate current and holding current.

Nice to know we still make quality equipment in England!!
Peak do a range of portable test gear in basically the same case.
i love it.. especially the zener tester. it can tell ya if its a voltage regulator as well. bloody brilliant.
Paul, I love to hear the trains. Thanks!
Hello Paul. I think you will find Gm is mutual conductance. Have a good day!
I bought the Peak Atlas DCA75 Pro some years ago, is and amazing tool, I use every day for test IGBT's Modules.
Save me a lot time in my repairs.
Wort every dollar.
Best Regards.
I love my peak esr. Want more of their stuff
I got an LCR-TC1 US Pocket Multifunction Transistor Tester for about $19 does everything except no computer interface. I use it all the time especially when you just read what it is.
The pc/testing graph feature is really handy to customize to your application
I have one of these and never knew it had a curve trace feature . Thanks
Hi Paul, I’m glad you like your new toy. You made me lol at the end, “and if you’d like to have this well I’m afraid you’ll have to buy your own”. K
Thanks again, its a really great piece of test gear.
Ah! You broke down and got one. I did the same. It helped me match up FET's and fix my Tek 475's little trigger-centering problem.
It's a bad-ass little dude.
I lamented not having a case so I googled and sure enough, they make 'em and they're on Amazon. Not too 'spensive either. I think it's worth getting one. I think it was $25.
PS: I actually very much enjoyed the train whistle in stereo in the ol' earbuds. (8^D)
Edit: ah, yours was on Keeran. Thanks, Keeran. Good on ya.
Man those Peak meters are some really nice kit. Cost a ton but worth the money if you work professionally in electronics. I’m definitely jealous. Great video Paul, you deserve the goodies that come from teaching all of us what you know, thanks for all you do man.
Thanks Mike, how are you doing?
@@learnelectronics been doing alright, just working on my synth. I’ll tell you that thing keeps changing trying to get all of the elements working together is a harder challenge than I thought but it is fun.
That is a keeper, enjoy.
Peace Paul. 🏖️
A great device and worth the $150.00 you pay, if you can afford it. Thanks, Paul.
Always with interesting topics :D👍
Really nice piece of kit. Thanks for the detailed look, Paul. Surprisingly, they are cheaper at Digikey.....$125.
Thank You
Keiran(sorry if thats spelled wrong) That was an awesome gift.. fair play to ya dude!!
Wow Cool...Love it when "Casey Jones" goes past your window...lol
Peak do a nice range of test equipment in the same format as your model but are, as you say, not the cheapest! They do have a great reputation over here.
I'd love to get one of them just a little out of my price range
Then go for one of the little Chinese component testers. Way cheaper, still incredibly useful.
@@JohnBailey39 I have and love my cheap tester maybe if I win the lottery I will pick one up. have a great day
@@dukeeod1650 know exactly what you mean. Mine is one of my most commonly used tools.
@@JohnBailey39 already have 1 just saying I would love one of these also
Lots of functionality and probably worth every penny. But it's not in my budget either.
Why didn't you open it up? They also sell those ESR/LCR meters and I have always suspected them of being the same cheap atmega based things sold on Aliexpress with a custom case and label.
This is a much older design, but it works good. It can also do leak current on Ge transistors for us buffs who make Fuzz pedals :-)
Paul, I have got to pick one of these magical devices up. thanks again for the great video. Will you be testing the DCA75? both of them come in a kit.
I'm looking into it
g_m is "transconductance." FETs use voltage to control current so their gain is mA/V, which is reciprocal of resistance=conductance.
also bjts have transconductance, but this instrument doesn't show it.
It would be nice to see you do an opamp tester circuit.
Hi paul peak do a range of this style of device like ones for zeners or capacitor esr and inductors also a non pro version of the one you got at half the price
Love ya Paul
That's a cool smart machine
What a cool device. Your audio is greatly improved.
BTW, did you get the question I left for you on your last Atari punk vid?
I *like* to hear the train go past. Sounds more... authentic somehow.
Nice unit, I wonder if it measures a transistor while in circuit to get a real time graph of it in use.
I doubt it would read in circuit as the base pin usually has a current limiting resistor and other shunt paths might throw the readings. Usually to check a transistor you could just check across base emitter an see if it's working with .5-.7 v drop tho 👍
Wow nice, wonder if such a device can be made with an Arduino and a few fancy ancillary circuits
It would be nice if the circuit symbol showed the wire color. I can never remember which one is anode vs. cathode.
So you have to compare Peak's readings to the parameters in the semiconductor's TDS to determine whether it's faulty , correct ?
I looked at these but was off put for the price. A bit pricy but maybe worth it for the curve tracer - if your scope couldn’t do the same thing. I think $50 would be more like it. You got this free - what is your idea for a good price?
These are not cheap. $150 is what they go for
@@learnelectronics even in the UK where they are made, they cost about £145 ($181)!!
Can you test components in circuit for troubleshooting with this meter
Nice
Were is the link?
Oh boy! Thanks. And it's not the size of a microwave like Tektronix of my youth.
What does the dca55 pro doe that the dca55 cannot do
cool stuff. how about a 50v zener?!
It can't, you can test zeners using the Peak Atlas zener tester.
Best Regards.
Atlas DCA Pro error shows NO Component when connected to
L7912CV
If I try to connect 2 wires only on any pins it detects it as zener diode. no reply from manufactuer.
Very nice if you can afford ot.
Cool, I bought one, but it’s on back order, have to restrain my excitement
Does not detect vloss for capacitors either, all chinese do.
👊👍👍👍👍👀
Test this against $14.00 models
