Re: [time-nuts] DC distribution

Hi where the wire is too thin for the crimp I actually strip the wire to long and fold it half One reason to crimp is so there is not a hard line for a fracture IE a point for the cable to brake By soldering the joint you actually introduce a potential fracture point It's all my time

Re: [time-nuts] DC distribution

Hi I am standardising on 4 pin XLR connectors for 12 Volts as used in the TV industry Perhaps you could use the 6 pin for 5 volts I do not recommend the 2 pin as this is for 240 V ac Or the 3 pin as you could take out a microphone I am going to be Using military connectors for 24 V DC and 400

Hi Dave I posted the question as I am not up to speed with the latest solutions But I want the lowest phase noise that is easily possible so you might be correct as it is to lock up a 10 Ghz receiver but later for a 120 Ghz receiver Regards Paul -Original Message- From: time-nuts

Re: [time-nuts] GPSDO 10MHZ Splitter

Hi you can always use a resistive splitter So if you have an output impedance of 50 ohm You use 2 off 50 resistors to feed 2 off 50 ohm loads / signals to other equipment with a 50 ohm input So we have a load comprising of 2 off 100 ohm loads in parallel = 50 ohm This method is often

Hi just a thought Video distribution amps for analogy video have been talked about Video is typically 7 mhz so they should work OK The input signal is looped to each amplifier input and terminated on the last amplifier input with a resistor for video it is 75 ohm but for a reference signal
