For example, I can take any of my sensors,
which are marked to have a 50 dB range and connect them to a signal generator. I
start out with the maximum level indicated on the sensor and all is well. I go down 10 dB
on the generator and the 436A follows, 10 more dB it still follows. Now, go 10
dB more and typically it goes under-range and no more reading. I just tried it
using an 8484A which has a stated range of -20 dBm to -70 dBm. With -20 it is
OK, -30 it is OK, -40 is OK, now I go to -50 and it just reads -4 indicating
below range. Before applying power the readout showed a -7 indicating it
properly detected the lowest range of the sensor. So, what¡¯s up? Thanks -
Mike

Hi Mike:
How are you making the measurement?
