No master oscillator. Complete and untested otherwise. has counter to 512MHz. GPIB. 35$ plus shipping
Good deal. I'd think most around here have a 10 MHz source to feed it with, so the lack of OSC shouldn't be an issue. I'd jump, but already have two.
I will point out that the HP 5328a counter has a function where it can act as a (1:10-1:10e7) decade divider. It's in the documentation, but not obvious. One nice thing is that the input is subject to the level and slope controls, which are much more capable than what's found on most simple dividers, so you can work with a wider range of input signals. It may work even without an internal OSC!
HP: "START A, STOP. Sets the counter to totalize the number of events at the A input until STOP is selected, for N=l on the RESOLUTION switch. For N>l, the number of counts divided by N is totalized. The scaled output (i.e., frequency of A/N) is available at the Time Base Out rear panel connector."
I don't know that anyone has characterized the jitter when using this feature, though.
