A BNC socket providing an
AC
signal for connection to an external filter set
or other external device. The Sensitivity is 200 mV
/ms-
2
(weighted
or
unweighted) with a DC offset
of
300 mV maximum for the WHOLE BODY
mode, and
20
mV
/ms-
2
(weighted)
or
2,0 mV
/ms-
2
(unweighted)
in
the
HAND-ARM mode, at the appropriate reference frequencies. Output
im-
pedance is
50
n and minimum load impedance is 5 kn.
A BNC socket to return the externally filtered signal
to
the 2512. Maximum
signal level is 5 V peak. Input impedance is
147
kQ
in parallel with 100
pf.
Sensitivity is 200 mV
/ms-
2
in the WHOLE BODY mode, and 20 mV
/ms-
2
in
the HAND-ARM mode.
For grounding the instrument. Accepts plug JB 0002.
