PERFORMANCE
CHARACTERISTICS,
SPECIFICATIONS
Properties expressed
in
numerical values with stated tolerance are guaranteed
by
the ma
nu-
facturer. Specified non-tolerance
numerical
values
indicate
those
that
cou
ld
be nominally
expected from the mean of a range of identical
instru
ments.
This specification is valid after a warm
-
up
time
of 30
minutes
and
f
or refe rence cond itions
of
mains voltage, ambient temperature, relative humidity, air pressure, and
ai
r
speed, see
c hapters 4. 8, 4. 9. Unless stated, parameters measured
at
the signal output
a
pply
with
a
50
fl
load,
0
dB attenuation, and
no
DC
offset.
Unless stated, relative
or
absolute to lerances relate
to the set value.
