With the K3's option for external time base synchronization, there may
be some interest in low cost distribution amplifiers.
If you have a high accuracy time base, such as a Rubidium standard, or
GPS-disciplined crystal oscillator, you may wish to connect multiple
devices to one 10 MHz output. Traditionally this is accomplished via a
time base distribution amplifier, perhaps the most well known example
being HP's 5087A.
A recent suggestion on the Agilent mailing list suggested using an
inexpensive video distribution amplifier with separate Red/Green/Blue
channels, to distribute timing signals. I've acquired an Extron 6 300MX
video amplifier and it works well for this purpose. I've provided photos
and frequency response measurements in today's update at
