Yesterday I was a little bored and I was staring to a box full of quartz cristals. I was wondering what frequency was, especially a very old one with russian marks on it. I know from an elder that the number on the Russian cristal is not the frequency but some sort of code. Stupid, eh?After I contemplate various possibilities of transistor oscillators, I came up with a simple, reliable and versatile TTL configuration, 'a classic' to say it simple.It's a 74LS00 oscillator in series configuration, the schematics is pretty self explanatory.Now I cand measure with precision the exact frequency of my 38.9 MHz crystals which, by the way, are overtone! I will make nice filters for 12.95 MHz on long winter days!Without a quartz crystal, it self-oscillate around 50 MHz with a very nice sinus wave! Some are curious about my lab tools.Well, I do have some stuff collected in years.The most important tools in a electronics laboratory are the scope and the signal generator.My scope is a AGILENT DSO 1014A, a four channel 100 MHz 2GSa/s scope. I wish it was a analog one but they are very big and expensive.
Because you can use it on some measurements where a digital scope is useless due to alias issues.This scope is a nice one but, in reality, is made by RIGOL:-) Either way, it's a nice piece of equipment!Agilent's DSO1000A Series oscilloscopes deliver the performance andfeatures you'd expect in a big scope - and the portability and low priceyou require ina small one. They've redefined the economy scope by giving you more:more signalviewing, more capabilities and more productivity.Description from Agilent webpage:Capture long time periods with high resolutionAll models provide provide up to 20 kpts per channel of convenient acquisitionmemory standard. The scope will maintain high-resolution acquisitions evenat slower timebase settings so you can see the details on your signals.See your signals more clearlyThe DSO1000A Series incorporates a bright, crisp LCD color display. Youcan quickly view your signal from almost any angle. Unlike conventional scopesthat always require menus to be on, the entire 5.7-inch diagonal screen isavailable for waveform display as needed.True Zoom mode for signal details and contextDual display and True Zoom shows your entire signal and zoomed in waveformdetails at the same time.23 automatic measurementsAll DSO1000 Series scopes come equipped with 23 automatic voltage, time andfrequency measurements.
Press the Measure key to bring up the three you usemost often or display all single-channel measurements on the screen simultaneously.Sequence mode for easier debugRecord up to 1000 occurrences of a trigger event and then play them backto easily spot glitches or other anomalies for further examination. Store thewaveforms to internal or external memory (USB flash drive).Digital filtering on waveformsApply a real-time digital filter of your choice to the source waveformto eliminate unwanted frequencies from your display.
Digital filtering selectionsinclude low-pass, high-pass, bandpass and band-reject filters. Frequency limitsare selectable between 250 Hz and the full bandwidth of your oscilloscope.Advanced triggeringTriggering options for the DSO1000A Series include edge, pulse width, compositevideo, pattern and alternate channel trigger modes.
These modes ensure thatyou can capture and view hard-to find signal conditions.Make fast go/no-go decisionsAutomatic pass/fail mask testing comes as a standard feature on all 1000 Seriesscopes. Acquire a 'golden' waveform and define tolerance limits to createa test envelope.
Incoming signals will be compared to the allowable rangeand quickly flagged as pass or fail. This is ideal for manufacturing or servicewhere you need to make decisions quickly.Waveform math and FFTStandard math functions include addition, subtraction or multiplication ofany two input channels and Fast Fourier Transform (FFT) with four user-selectablewindows (Rectangle, Hanning, Hamming and Blackman).Programming and ConnectivityFor remote instrument control over USB, use Agilent's I/O library or NationalInstrument drivers in your application. The drivers are compatible with AgilentVEE Pro, National Instrument's LabView and LabWindows/CVI.Built-in USB host and device ports and free IntuiLink software make documentationand PC connectivity easy. Store waveforms and setups to a USB flash drive,easily update scope firmware and print to any PictBridge compatible printer.Here is a flash movie, pretty self explanatory. The signal generator is a ZOPAN KZ1405 Function Generator produced in the 80's by the Polish Institute and Scientific Equipment Manufacturing -Zopan.It covers 0,01 Hz - 10 MHz in square, triangle and sinus waveform.
It's a well built analogic signal generator and it works very nice. Only a little contact spray to the potentiometers.Has sinusoidal, triangle and square wave forms, all of them with variable ratio (they call it 'symmetry') and a very usefull offset setting!Very, but very simple and reliable!I will change the capacitors when I will have some time because I suspect that some distorsion at 0-10 MHz due to ageing.Some guys thinks the KZ's are adequate for making music. Well, I don't!from on.Thanks to a great Polish guy, I do have the schematics for my Function generator! I wrote about, the new multimeter in my shack.Well, I told you that I have a very old DMM, a Voltcraft VC98 with 3 and 1/2 digits.I bought it from my first wage, back in 1995 and was around 200 USD at that time. A lot of money!I never succeded in my trial to make him communicate with my PC via IR.It has no autorange, the selector is a pain in the a&.^&. but it works! Yes, it works perfect and even has a bargraph wich is very nice.
It's a backup DMM in my shack.The other one is also a Voltcraft, a VC-960, top of the DMM in 2011 if I remember right. Have some issues with it but manage to make it back in service. At least at 90% (still have some problems with AC current measurements).Here are some pictures:The VC-98 near the VC-960.

Well i decided to buy a newer multimeter for my electronics works and so will use this mainly around up to 50V AC/DC: Got it delivered yesterday from conrad: It is on sale here right now in sweden and is on sale for like 50€ so i know it might not be the best quality like fluke, appa and gossen and so on was a bit curious on how the inside of this meter looked like so i took it apart and took some photos of it. The feeling of the multimeter otherwise in quality feels pretty solid it got 4 screws holding it together and the input jacks are pretty solid compared to uni-t ut61x series where there is a flimsy little metal tube pushed down in the front and held down by the back cover it also warn you of cables in the wrong terminals too, me i find it pretty ok even if i know well enough not to use the wrong inputs and so. I have looked at the construction and i like it pretty much seems to have both ptc and movs and a bunch of serial resistors on the input 3 x 33m? And 4 x 2.5m? Before the input of the ic seems pretty ok and after i saw the other side of the pcb i am pretty happy with this unit. So updated the post with more images of both sides of the pcb, and i changed the thread name as it became a teardown lol.
I bought this meter about 2 years ago, also for €49,99 (special offer). I was planning to post a teardown of it here (already made the photos), but never got around to it and Hagis2k beat me to it. Considering the rather poor accuracy specs I doubt that UNI-T went to much trouble calibrating/adjusting this meter. Unless you get any response from Conrad or UNI-T (I wouldn't hold my breath until that happens), probably your best bet would be the datasheet I linked here before and a bit of reverse engineering to figure out what the pots in this meter do. Before you start playing with these you better have access to some kind of reference that is significantly more accurate than the stated accuracy of your meter.
Anyway I wonder why you care. The VC-850 is simply not a precision instrument and it is not going to be no matter what you do with it.
For many purposes its accuracy is good enough, but if you need really accurate measurements this is the wrong meter. Compared to my Fluke 179 (stated DC volts accuracy: 0.09%+2 digits, which is average at best but still a lot better than the VC-850), I noticed that the divergence is not uniform across the voltage range. At some voltages the indication on the VC-850 is a few counts higher than on the Fluke 179, at other voltages it is a few counts lower, and at some voltages they pretty much agree. A simple adjustment won't make those all go away.
