I'm so glad you asked before buying.
I hate having to tell something they wasted their money.

Hi,
Quick correction, I wrote "HP 5314A and 5314B" and meant "HP 5316A and
5316B" which is the relevant here.
Sorry for that blunder.
Cheers,

Thank you Paul.

Thanks for your insights Rick.
The manual specifically states: "The HP 5316B does not actually use the
external input signal for a time base but locks-on to the signal with an
injection-lock-multiplier. The external signal must be 1,5, or 10 MHz"
My only experience with injection
Wes many of the HP sig gens and counters use that method I might guess

are as good as the external reference is.
One gotcha. It seems some people pull the oscillators to sell on auction
sites. So if its missing thats a bit

Hi
The “typical” HP counter for many decades has phase locked an internal
oscillator to
the external reference. I have not seen any designs that use injection locking.
Given the
somewhat crazy math associated with injection locking, this is not a big
surprise.
By modern standards the 5316 is
As I understand it this counter has an external reference input that isn't used
directly as the time base but injection locks the internal time base. Does
anyone here know how well this works. Is using a GPSDO as a reference a
worthwhile accuracy improvement?
