Rebonjour a tous:
My experience is with
HP RF gen 8640B, counters, spectrum/network analyzer 4195A and synthesizer 3325A
Yokogawa scope DL7440 and time analyzer TA720
TEK scopes with REF input (2465B CTT options)
REF inputs use 50 Ohm inputs with wave shaping, so not critical for waveshape, sine, square, pulse ~ 100 mV or greater.
We set our Leo Bodnar Mini GPS, set for 32 mA (max) RMS output
http://www.leobodnar.com/shop/index.php?main_page=product_info&products_id=301 Measured square wave Trise ~ 650 pS (on 500 MHz Yokogowa DL7440) , 1.8V P-P into 50 Ohms
We distribute as a master clock with 50 Ohm BNC passive (transformer) splitters, we can drive 4...6 instruments easily.
10 MHz capable 2X, 4X 6X and 8X splitters are common, e.g. Mini-Circuits, with BNC, SMA, N and other connectors.
With a 4 way splitter Merrimac, we got 930 mV P-P on each output and ~ 3 nS Trise.
Even after a 6way split the outputs are 200 mV or more, so all instruments sync.
https://www.minicircuits.com/WebStore/Splitters.htmlOld Splitters are on epay, eg Blonder-Toung and Merrimack.
Even old CATV cable splitters (F connectors) work, at 10 MHz.
Hope this is useful!
Bon Chance,
Jon
