Hi "anonymous",
 
the 53132A only does that for a couple of nanoseconds. Then it jumps to a  
stupid value such as:
 
 
0.004 us
-0.002 us
0.999,999,993 s
 
It get's even better when the counter decides it doesn't have enough  
resolution in frequency mode:
 
2,3** u
 
Absolutely horrible to parse, these guys should have heard of scientific  
notation. Not sure who programmed that unit, or if there is a firmware  
upgrade that gives proper numbers.
 
bye,
Said

Counters  like the Agilent 53230 actually WILL output negative delays 
in this case  as long as the delta is still small. This is a quite useful 
feature in  such cases...
