HP frequency counter 5342a

Hi, I am looking for technical advice on my HP freq counter model 5342A.
It works fine from 10khz to 500mhz. On the other range from 500 mhz to 18ghz
do not measure. Do anyone have the same problem? +5v and -5v on the sampler driver
is ok. Apply i/p say 1296mhz and try to measure at the o/p of the sample driver by
spectrum analizer at the o/p but nothing at all. My friend 9h1bn have the same problem too.
Could anyone help.
thanks
