Hi! I just want to ask if is it ok to use a different wavelength when testing a fiber optic cable used for transmission line or for OPGW? For example I am using a singlemode fiber with 1550nm wavelength, is it ok if I will use 1310nm wavelength for testing?
Hi! I know this is quite a very simple question, where we all know that once a circuit is open we can measure a voltage equals to the supply voltage while the current is zero, but I want to fully understand why and how? why is the voltage be equals to the supply voltage at components before the...
Hi! I am working on a PCB design, which is for audio DSP, I want to avoid ground loops. How should I connect the grounds? Where should their common ground connection be? any suggestion guys?
Hi! I would like to sync multiple digital clock using an NTP server and I am want to know if there are any application that can be used to connect to a NTP server?
How To design a clock network with NTP mutlicasting configuration
Hi! I am new with NTP, and I would like to synchronize time setting and display for multiple digital clocks. I have checked few sites but it does not show example for the network/system design. Can you please help me on to start...
Hi! I have to multiple clocks which are from 2 different clock brands, and I want to create a single network among the clocks where I can set the time and will automatically apply to all the clocks. Will a universal Time server a good idea to interconnect the clock? Or do you have any idea on...
Hi! I am trying to load program in PIC16LF1939, but as I connect the PICkit 3 and sets the operating power to 3.3V it give me this message.

I have attached the schematic and PCB layout for the FTDI and the EEPROM, and so as a screenshot of the FT_prog for the FTDI.. I am thinking right now the possibility of a damaged FTDI, i have tried to replace the EEPROM twice but get the same response;(at the EEPROM) there is No clock pulse at...
