Special
4:
Disable Output Blanking
When the amplitude of
a
signal being output
is
changed enough
to
cause a change in the setting
of
the discrete attenuators on the output board, the
signal
is normally shut
off
or
‘blanked’ to prevent
switching transients
from
being output during the change. The blanking normally
lasts
about
14
msec.
Enabling
this
special tells the instrument
to
continue
to
output the signal during the process of
changing the attenuators, thereby reducing the amplitude switching time
to
about
2
msec., but allowing
any switching transients that may be present to be output in the process.
Special
5:
Floating Outputs on Power Up:
You can pre-define whether the output(s) will be floating
or
chassis ground referenced when the
instrument
is
pmered-up.
