A mating plug is furnished with each
instrument .
For example, to programanattenuation of
106 .5
dB,
pins 14, 7, 8, 10, and 12 of
the LEVEL
PROGRAMplugmust be grounded,
then to reduce the attenuationby 6 dB
(i.e . 100 .5 dB), ground is removed from
pins
7 and 8 . (Note that O dB reference
point
is +13 dBm .)
