A pc based usb oscilloscope,high quality ,low price. uso-2300 series,20M/40M/60M/100M/200M
Hi everybody I've used my PC's sound card as a very basic oscilloscope for a while now but since I switched to a laptop which only has a mic input (very high sensitivity and can't be relied upon because of internal filters) I decided that I need an usb oscilloscope. Plus I'd like to upgrade the bandwidth. I searched on the net for (...)
Hi all, If some one has the circuit diagram of DUAL CHANNEL usb oscilloscope published in ELECTRONICS FOR YOU 2006 DECEMBER issue please post it.Our college library has one copy of the particular issue but it is closed for some days.the circuit diagram that i am able to download from Efy website is a blurred one so please upload the circuit diagr
Hi, Does anyone have any idea what parts are inside the "Swordfish" Hand Held usb oscilloscope (ADC,UC,RAM,FIFO...) ? Thanks
Hi I have one of the older Bitscope, I am not satisfied with the frame rate when updating. The new ones is much faster and have ethernet / usb. I depends upon the budget, last time I checked the PICO were more expencive. It also depends if you like to buy a finished product or build something yourself. If you have money I would buy a external
Hello Friends, I'm planning to make a computer based CRO using usb.. Earlier I have made a computer-based CRO using the parallel port & PIC 16F877A... Now I'm planning to use PIC 18F4550 which has an inbuilt usb module... However, the 18F series is much different from the 16F series.. I'm currently reading the data sheet to understand the wo
usbscope50 is very tiny usb scope,i also want to made a home scope,anyone can send me usbscope50 schematic. Added after 5 hours 14 minutes: very beautiful scope
Hello everyone. This is my first post in this forum. I am a student of 4th B Tech (ECE). I have planned to build a PC based usb oscilloscope using PIC 18f4550, to plot high frequency signals upto 10 MHz, in these vacations of mine. I am thinking of using external ADC made by TI for signal sampling,( TLC5540) which has sampling rate upto 40MSPS,s
usb control is the simple part of your project. For the other, it depends on the specification. If you regard acquiring of kHz audio signals as "DSO", it can be simple too. Several 10 MS/s, as achieved by typical usb oscilloscope black boxes, is already demanding. It requires special hardware and a profound analog and digital electronics (...)
You're not going to get that kind of range and rate in the same device, expect. At least, back when I was working in 30V technologies you couldn't. More likely you will have a switched attenuation network at the front end (your vertical/div) and work with whatever ADC provides you the sampling speed / accuracy you want. You would have
Hi all , I got the circuit from following site it works usb oscilloscope

Hi all, I'm designing a PIC32 based usb oscilloscope. I need a dual supply for the opamps as it simplifies input impedance and level shifting. I selected a unregulated +5V to +/-5V DC to DC converter (needs to be isolated so this limits my choices here) and then I was either going to use +/-3V LDOs in front of this to provide the supply for the
Hi ! i m doing usb oscilloscope as my FYP i m completed hardware circuit now tell me how to use A to D converter of PIC 18f4550 to convert analog signal to digital plz give me a sample code I begin to think that I am the only user of Google.
Hello all! I must resolder Picoscope2000 wires. Does anybody know whether a Picoscope2000 schematic diagram is available somewhere? Thanks a lot gusts
Hi! Here's a cool hack I came up with during the weekend, and surprisingly enough, proved to feasible: Capturing composite video NTSC signal with a usb oscilloscope (Picoscope 2204 to be exact, they have a nice C API), and decoding it realtime to emulate a composite display in
Try using oscilloscope and see what's going on with voltage lines on your processor. I am assure it is best method. usb oscilloscope and DSO oscilloscope, helped me alot with low frequency signals, power lines, data lines, etc. problems. Cheap, frequency is enough to find all kinds of problems. Also: Maybe you make too much (...)
Hi Does anyone has seen a oscilloscope home project on the web that can be connected by means of usb 2.0 ? Thanks in advance.
I was wondering how to use an WinTV usb card as an oscilloscope, becouse it has an SVHS input and probably we can expect at about 5 MHz of bandwith. I was thinking on using vendor drivers from Visual C++. Any help with usb routines or how to program in low level such hardware? Thanks in advance. :)
Have a look at this one they do a PIC18F2550 KS0108 Graphical LCD oscilloscope and usb scope using a PIC18F2550 sorry forgot to add wizpic
everyone!! Im planning to buy this oscilloscope from ebay. Does anyone have used this oscilloscope? any comment regarding this? thanks. :D
I've searched the forum, but there seems to be no update on the threads asking for a usb PC oscilloscope project. Personally, my needs are fairly simple, I just want one that can show square waves at around 5kHz - this is too fast for an audio card version. I found these on
can anyone share a schematic of a usb-based oscilloscope? thanks!
Hello guys! I need to build a MATLAB GUI that can read and display real-time data from my usb port. It will work like a virtual oscilloscope. I cant do that! Who can help me? If you have any files that can help, please email me tks in advance!
I want to get a spectrum analyzer to learn and view charactarictics of various audio shaping circuits (so I'm staying in the DC - 20KHz region). My options are getting a 150$ - 200$ usb based scope that comes with a spectrum analysis software. There are various manufacturers here but the spec. is pretty much the same. The other options is to get an
Several years ago, I posted a link to a PC Based oscilloscope project I was working on. was some interest, however, most of the requests were for a usb connected oscilloscope. Well, I finally got around to incorporating usb into the project
I am designing 100 MHz scope + 100 MHz logic analyzer on usb bus. In future, I plan use FireWire interface for data exchange between board and PC. I think it is better idea then use slow COM port
Hi. In essence this signals are digital in a diferential configuration. In usb you have signals levels for different sates of the port. For example some levels are "disconnect", etc. You can find more information here: or in the usb standards. Regards.
Yes you can buy PCI or usb digital oscilloscope, just search google for pc based oscilloscope. Here are some links for PC based oscilloscopes:
Salam, 8051 is slow to count external pulses, use PIC instead because it has internal prescaler attach to TMR0 (Counter). Bye Or better Ubicom IP2022, that have speeds up to 160MHz (and also 160MIPS), 4K data SRAM, 64KB Flash, 16KB Data/Programm SRAM, S232, or usb, or Ethernet ( need only external magnethics).
I have downloaded the software in the 1st post and it works with me. Can I connect this software to an external circuit via cables(RS232, Parallel, usb, Firewire). It's really important for me. Thanks very much for your help.
Can I connect this scope to an external circuit using cables(RS232, Parallel, usb, Firewire,..etc).???? If yes, What is the interface circuit.??? Thanks to all of you.
I want to modify the design of PC base oscilloscope given here But the bandwidth is limited to 500kHz due to the FT245 usb data transfer limitation of 1MB/s. I want to increase the bandwidth to something useful like say 20MHz using high speed ADC (40MSPS, 8-bit) and FIFO buffer. Now the problem is that how
Hi I read that for compliance test usb output has to satisfy a particular eye diagram. Can anyone point me to the actual algorithm used by scopes to obtain the eye pattern for this? Basically, I want to know whether only cycle-cycle peiod differences are important or is the accumulated phase also important. If anybody knows this please tell.
Bitscope natively uses Serial Port (RS232 using PIC16F628) Communication, which is then converted either to usb or ethernet, depending on model you choose. So screen refresh rate would be a rather low. I would suggest to go for a pure usb version, something like these (Good Features and S
hello! can anybody tell me about the max baud rate for usb 1.0? im having an pc based oscilloscope project.. how will i know the max frequency that my oscillscope can read correctly? im using pic16f877a, max3100, and usbmod3..
hi i designed a digital board (computer motherboard), where there is a usb HUB (SMSC usb2504) connected to one usb port of the south bridge. There are some on-board devices connected to other ports of the south bridge, they are working. The Hub can be configured using SMBUS, or with internal default configuration. If we try with SMBUS, (...)
