Measurement of the second LO on B sampler :?

Measurement of the IF out on B sampler with a cable between port 1 and 2 :
?
?
The output of B sampler seems to be KO (should be about -15 dBm at 37 MHz). Is my B sampler dead ?
?
Measurement of the A5 sampler (middle one, with nothing connected on port 1 and port 2):
?
?
I have about -8 dBm, this sampler seems to be OK.?
?
Measurement of Sampler R (with R cable connected on A channel):
?
?
?

I measure about -18 dBm on the output of R sampler. It seems to be OK.
