Distributing reference clocks and triggers in a lab

(1/3) > >>

Hi,

Let's say I have several instruments and most of them can take a 10MHz reference clock and all of them have both trigger input and trigger output.

Now I'd like to be able to distribute the 10 MHz from a single clock reference to all of them and also be able to configure the trigger in/out dispatch without having to plug/unplug cables.

Does any one have recommendations for one or the other ? (somehow I doubts BNC 'T' will do ... it'll half the power each time and it's already only 0.5 Vpp in 50ohm at the clock ref output)

sacherjj:
This still may be fine.  If you connect them in parallel, they will all still be 0.5V.  The question then is if you have enough power to provide the needed current to all of them.  Generally the input requirement is much less than the outputs, so you might just be able to T everything up.

mikeselectricstuff:
 video distribution amp may be an off-the-shelf solution - composite one may ebe marginal but an analogue VGA amp ought to do it easily

DavidDLC:
What we do is to have a common signal distributor (10 MHz reference) and then small amplifier/conditioner/filter units right before our instrumentation. But our production line is noisy.

We don't have the trigger connection that you mention.

Huh ... it won't be be 0.5V if the source impedance is 50R. It'll end up be 0.2V after 4 devices.
