Vertical Channel Setup Program - HP 54501A Programming Reference Manual

Vertical
Channel Setup
Program
This sample program demonstrates
some
of the commands
used to set
a
vertical channel, in
this
case channel
1.
The
program assumes that the
AC
CAL signal from the rear panel
of
the instrument
is
connected to channel
1
through
a
10:1
probe.
The program
sets
the probe
attenuation factor for
channel
1
to 10:1.
