    Oscilliscopes

    If you had $350 to spend on a scope, which one would you get?

    And does anyone know of a sub $50 multimeter that can read down to the 10s or 100's of µA ?

      You might have to spend a little bit more money than this to find a good quality one for the money

          you dont get tek or hitachi for that price unless they are 20years old.

          that money can buy a brand new 4 channel scope from rigol or siglent

            Here is one model that might what you are looking for not this model number though

            MASTECH MS8239C

            I have use a Mastech meter before at a job over 10 years ago and back then there meters were pretty good back then I have no idea what kind of quality they have now

            Or this model that the picture is below I have used this meter for a while I have not used the UA setting before but have used the milliamperes scale and the amp scale and have no complaints about the use of it

            It does have Bluetooth capability and does work pretty good with the Apple application it works fairly good easy to use but it is very basic in design

            If I remember correctly it was under $50.00 on eBay

            I hope this helps you

              My Sencore SC3100 I bought new for a lot more than $350 has been a great one. They can be had now in your price range. 100MHz, dual channel. Built in DMM and frequency counter.

                  I own a Fluke 117 and had I known at the time that micro amps would be important, I would have chosen better. Just feels wrong to spend that kinda money again just to get microamps when I've got a good meter.

                  I dunno ... I'm sure ill end up biting the bullet and springing for the right one.

                    So Amazon has two Rigol's around $350 ... this one is a 2 channel 200Mhz and this one is a 4 Channel at 50 Mhz

                    THEN, I saw this sexy lil thing ... but it's a buck and a quarter over budget ... yet it might be worth it.... But just look at it ... it exudes class and style and it says ... "I'm gonna be here for a long time doing a damn good job"!

                      So as I was looking at the Siglent page, I noticed a timer counting down at the upper right. When I clicked on the scope, the price was $474 ... but that timer was telling me that I had just 10 minutes to take advantage of some deal I stumbled on and the scope was at $424 ... so figured since I'm Amazon Prime if for some reason I don't like it, they will take it back no questions asked.

                      I went ahead and got it... should be here Monday.

                        Here is the scope I ended up buying. It should be here Monday. It was a little over budget, but it seems highly functional with some cool technology in it including a web interface that can be accessed from anywhere. :-)

                          Re: Oscilliscopes

                          a very good scope.
                          i think you can even hack the software to upgrade it to 200MHz.
                          there is a thread at eevblog about that.

                          same for the rigol btw, you buy the 50MHz and unlock it to 100MHz.
                          but the siglent is better - and can go to 200MHz

                              Very nice!

                              I just haven't been able to let go of my old CRT scope....

                                what i want for my collection is a hybrid design from HP.

                                just before they went to lcd they produced a range of traditional looking scopes that where actually digital with a mini CGA? (24KHz) monitor in them!!!
                                the top model was colour!

                                unfortunatly every time one is on ebay some scumbag collectors who will probably never use it bid them up to stupid prices!!

                                same thing happens with HP bench meters - i know for a fact some of the buyers have 5+ of the same model just stacked for display/bragging rights!

                                  So it's already capable of 200Mhz, just have to hack it and enable it? ... sweet!

                                    Maybe you could find a broken one for a good price and fix it?

                                      I just haven't been able to let go of my old CRT scope....
                                      If you got table space to throw away ... then more power to you!

                                      I'm kinda the same way though ... if it works, seems like a waste to buy another one. That's why my last laptop was almost 10 years old before I bought a new one after it finally gave up the ghost.

                                      I even tried to save the old one... it just kept shutting down for no reason and after a lot of troubleshooting, I figured there must be microfractures in the lead-free solder on the mainboard somewhere so I even stuck the mainboard in the oven for 10 minutes to re-flow the solder. That actually worked for about a week or so till it started shutting down again... each time the re-flow only worked for a few days ... then a few hours ... then I finally just called the time of death and stopped CPR and bought a new one lol.

                                        Maybe you could find a broken one for a good price and fix it?
                                        they are already broken on ebay.
                                        they are bragging to each other = posting pictures of their "collection" on eevblog!

                                          Does any one have any opinions on the Siglent SDS2352X-E scope, are they reliable? I almost got the 300Mhz 2Ch Rigol, it seems Siglent has the edge.

                                          Reading input and output of bridge rectifier on the same scope?
                                          by EasyGoing1
                                          I have a 40 volt AC transformer that I put a bridge rectifier on, and I wanted to see the input signal and the output signal on the same screen on my scope, so I set one channel up with the test lead on one side of the input and the ground lead on the other side of the input, then I used another channel on the scope and clipped the test lead on the positive side of the output then the ground on the negative side of the output.

                                          When I connected the transformer to power, the wire that was connected between the ground lead on the second channel and the negative side of the bridge rectifier...

                                          Lenovo Ideapad 100S-14IBR

                                          need help guys.. Bios ic UX3 - 25Q64FWSIG no 1.8 volts

                                          shorted 1.8ALW volts to ground. eeprom is ok


                                          Findings : i disconnect the vcc from the circuit using jumper 1505 and test the output of the 2Z-3F F0V ic it produces 1.8v so i injected a 1.8v in the vcc of the eeprom and somehow the processor is heating up and it draws 2.090 amps .

                                          my question is how much current does this ic can produce at normal level. does the 1.8vALW powered the processor.

                                          am i dealing with a shorted processor?...

                                          I am thinking of buying a component tester but I want to get the most out of the device for the money that I am going to spend

                                          Any idea but I would prefer actual use of the device it good points and it short comings be completely truthful about the review of the device

                                          There are so many versions of this type of device and I do not have enough information to make a good decision at this point

                                          When I bought my battery testing machine I had some information to go by because of electrical experience with auto electrical experience in this field job wise (...

                                          Hi. Could anyone with knowledge advise if this pcb in photos can be repaired? I'm willing to spend time and money on it to gain experience however I searched net for schematics and couldn't find so it's impossible to know what are some of burnt components. I can't find any second hand replacement board and new one is out of my budget and it exceeds value of cooker. I'm new to this forum but have had few successful pcb repairs of tv's and cooker pcbs and also made few working circuits for fun. Any help appreciated. Regards....
