test using HP53123A:
The pink line is the noise floor using the TI mode
The blue line is the noise floor using the Frequency mode (gate 2
sec)
The other two line are the same oscillator, an HP105B tested with
both the modes.
As you can see the range between 1 and 200 sec is "totally
compromised" by the system noise floor using the TI method.
The approximation using the freq mode can be anyway usefull to make a
comparatinon between two source.
I suppose to have right measurements, without any restriction we have
to use the Timepod or other high level instruments than this kind of
counters.
