50ohms, but you will pay about three times the price. Use the adapter, it's
$16 from the link below, it just isn't worth taking apart. Also, you will

I believe the voltmeter is calibrated for 75 ohms, not 50, otherwise they
are very similar. You can apply a dB offset to correct for the measurement
error, run the input at 10Kohms, and use a 50ohm feedthrough termination.
I own both (the B is has problems now), but I use the voltage
of the A being a 50 Ohm instrument.

Abhay,
The microprocessor learns the drift of the oscillator while it is connected, so that when GPS is lost, it can make
those corrections in anticipation of drift. The longer it's locked to GPS, the better it learns the drift (more
history). Don't confuse the word drift with locked, even
difficult.
In addition to the wiring options you can (obviously) have either a male or female on either end. There are so many
odd pieces of gear out there that you can have pretty much any combination.

on the net.
Hope that helps a bit.
