As with digital logic you can run into "fan out" issues...I used to use even more "ported" (is that a word?) Mini Circuits passive splitters to feed my 10MHz bench referenced test gear. But as more and more instruments were added the outputs began to fall below the reference input requirements of the devices. Powered dividers provided the answer and in those cases the cross talk wasn't as important. TAPR still makes a good one with 6 outputs (have three of them all full!), although the case to put them in isn't available any longer. Thanks for sharing as usual!
@@IMSAIGuy Yep, for instruments like analyzers, signal generators, VNAs etc. they're probably not all that great. But to just distribute 10MHz around I think they're ok, although I suppose cross talk could introduce some modicum of a phase noise jitter effect from the test equipment's input circuitry that accepts the standard and comes back down the line so good point to at least consider, thanks!
I have a 4 port and 8 port mini circuits power splitters. I would like to measure them also with my NanoVNA. But I only have the 1 load, from the NanoVNA kit. Is there a way that I can measure this with this current setup? Or do I need to buy more RF loads? Thanks. MikeK

I found a big problem with them, crosstalk. The TInySA is really noisy and getting back into the good SA. I will be using a coax relay to switch.

@@PapasDino oddly, a video will post on the 11th where I talk about a distribution amplifier for my 10MHz cal reference.
That HP power divider - Agilent Keysight HP 04192-61001 Power Splitter - is an accessory to the HP4195A. I made one myself with 2 resistors
yes it was part of a kit. it included two bridges forward and reflected, a load, and the splitter. I have all but the forward bridge.

you need more loads.
Any reflection bridges to show?
I've shown reflected bridges in other videos. Not using the nano but on the HP8921
Hello Sir.Can you demonstrate how to measure antenna gain using TinySA.Thank you.
The TinySA will not be able to test antenna gain. You need specialized equipment and laboratory conditions.
