Best Deals for Oscilloscope Multimeter Generator,Cooling Fan

Fast delivery (12 days). Arrived in very good conditions. The HDS242S oscilloscope function is great, better than expected. Tested up to 25MHz using the internal signal generator....Yes,it can run in parallel while using the multimeter or the oscilloscope. Frequency and voltage very where very precise. I compared the measurement with my Owon VDS1022i PC oscilloscope and shows the same values. I need an external function generator to test it up to 40MHz, but for now it works fine. The Auto adjust mode function takes few seconds to adjust the freq and voltage scales. Very intuitive menu. It took me less than 15 minutos to realize about all the functions and settings without read the manual. Easy to use and switch between function. I used the internal AWG in a loopback to inject the 25MHz you can see in the pictures. I also tested the Windows HDS application to connect the HDS to my computer. The software is not as great as for virtual oscilloscopes but allows you to capture continuous data from your HDS oscilloscope. See the screen capture of my computer. In summary, great product for the price. I'm very satisfied. Thanks also to Banggood for the offer and the fast delivery.

Although proccesing time was a bit high (ordered Oct 4th and shipped Oct 15th) it tooks 13 days to arrive only. No import duties were applied fortunately. BG order team contacted me by email and solve the problem with shipping method. Satisfied. The engraver came well packet, inserted in foam. All parts complete, no damages. The only improvement point can be add an anti-static bag/foam to the controller board. Still pending assembly and first testing. Construction and materials looks robust and there is no signs of wobbling. I bought it cause wireless and standalone operation options. It comes with GRBL 1.1 firmware but can not be used directly with third party software (Lightburn, LaserGRBL, etc) but propietary Vigotec VigoWorks software only instead becasue the ESP32-WROOM has propietary firmware to connect to the CH330N USB interface chip and to the Atmel 328P procesor. However an small modification in the controller board can be done easily to make it compatible :-), using a 4PDT switch and small soldering to allow switch the board between Vigotec mode and third party software mode compatible.

jjjjmalic Not time tondo It nos but you can search for "VG-L7X" in GitHub and you wiill find a "VG-L7X wiki!!" article done by arkypita user (the "LaserGRBL" software creator). Then go to "Hardware Hack" section. You will find there how are wired the ESP32WROOM with the CH330N chip and the Atmel 328P. That way you will realize yourself how tondo It. Do at your own risk. Think that warranty expires with the modification. Good luck
