          A Clean Signal Generator for noise Tests

          I found this Great information Today !!! Just wondering if anyone has bought and used a Max038 I.C. chip for signal generation circuits . I found 2 circuit schematics that run from about 1 khz to 20 mhz . Actually I would only need a 1 to 100 khz generator , a TTL , sine , square or triangle waveform can be generated on the circuits I found . I am just trying to find the cheapest price. I want a signal generator that will have 2 outputs . And this will be a great test device for Golden Sabre Light noise problems using a dual trace oscilloscope and 1 channel of generator used at front end of golden sabre and the other to the input channel 2 of oscilloscope and the RX output to channel 1 of oscilloscope. I know this can be done , and plus I need a good signal generator anyway !!!............. Thanks...........Eugene

            MAX038 was obsoleted because they shut down the fab that made them. For a fantastic sig gen look at Analog Devices DDS chips.

              Carl , Thank-You !! Bad news turns to good news !!! Analog Devices might be a better product and maybe they have a better price !!! I will check it out asap...............Regards................Eugene

                  A clean signal Generator for noise tests.....

                  Thank-You Carl , KingJL . The price of the AD9833 is around $6.00 us dollars , not bad at all , because the signal to noise and THD specs are better than excellent !!! Now I am searching the internet for external signal generator circuits for the AD9833.............Thanks.................Eugene

                    Build your own Test Equipment !!!

                    I found out that you can still purchase plenty of MAX038's and I sure like this circuit I found today !!!....... Yes , the AD9833 is a superior or better chip , but the external circuits I found for it are much more complex and software is required . I think Maxim is stupid to discontinue the MAX038 chip........Here is one of the D.I.Y. "do it yourself " signal generator circuits I found , the pdf schematic and the Authors prototype photo . I will post more generator circuits using both the MAX038 and ones using the AD9833.........Regards..............Eugene

                      Here is another great little circuit from 2003 !!! 5 years ago !!! The ICL8038 is $18.00-$22.00 u.s. dollars , way over priced but still available in limited supplies........Regards...............Eugene

                        Build your own Test Equipment !!!

                        I found another function generator project . What I did on this one is , I put everything together in one zip-package . This project "KIT" is no longer available -anywhere . It can still be built and again , the MAX038 I.C. can still be found , if you search......This project was originally from a 1996 electronic magazine , and since the MAX038 i.c. chip is officially discontinued . It is ok for me to post this here , on this Great Forum.........Cheers...........Eugene

                          Hi Eugene,
                          Thanks, that´s a nice one.
                          Now i need to find that IC ...

                                Thanks Carlos for the information !!! The first file "xr2206" downloaded fast and looks good !! The second file has a problem ?? 6.98 megabytes , but it is still downloading , a few more hours , it is at 47% now . Thanks for posting these Projects , it is nice to have choices on what Function / Signal Generator to build !!!!! .............Regards..........Eugene
