On the Tektronix MDO4000 series instruments the delay is factory aligned
to within +/- 5 ns, but on
Reverting somewhat closer to the original topic:Attached 2 BJT circuit has
unity gain with a PN floor well below -180dBc/Hz (10MHz +13dBm input) with a
reverse isolation better than 60dB. 2nd Harmonic output is about -70dBc or so.4
of these could be driven from the outputs of a 4 way splitter to

Jim,
It really depends on the complexity of your system.
For some you can analyze it or measure it with fairly simple tools.
For other systems, you need to calibrate it with a signal of known
timing and compare the known timing out of the same box with that of
your system. This is how GPS/GNS

One simple way to look at it is:
The conversion process is a filter. It has an impulse response and a group
delay. If it’s a digital downconversion
process, those things are very well known (no analog drift …). You can, if
needed, put in correction filters to

Here's an interesting problem.
You have a fast sampler that is collecting samples off-the-air (e.g. the
end of LORAN) with a fairly wide bandwidth: say 10 Megasamples per second.
Those samples get post processed in a digital downconverter (not
necessarily in real time) to a narrower band repr
I once spent a very miserable but profitable weekend remaking a thin
ethernet network where the "installation expert" had stripped back 10B2
coax four inches and neatly separated core and shield, heatshrinked them
into pigtails and then soldered them into panel mount BNC sockets.

The radio (B210) runs with either of the I7 laptops that are here.
As you point out, making sure that the bus speed and devices are
compatible is key.
The B210 is a "development board" so to sp
