Switch Management
Switch sequences allow you to define and
control complex signal paths with user as-
signed names. Sequences can be nested
and called from your program. Up to 500
sequences can be defined and stored in
non-volatile memory so when power is
lost, the sequences are not. Use sequenc-
es and the break-before-make features
to ensure switch closures are made in the
right order and eliminate possible damage
to your valuable DUTs or test equipment.
See Figure 6.
Switch counts are also stored in the
instrument’s non-volatile memory. So you
can monitor when a a switch is nearing its
end-of-life.
Additionally, power up/down states can
be identified and stored in non-volatile
memory, protecting the DUT when power
is lost.

Graphical Web Interface
The built-in graphical web browser inter-
face provides remote access and control
of the instrument via a Java-enabled
browser such as Internet Explorer. Using
the web interface, you can set-up, trouble-
shoot and maintain your instrument from
anywhere on the network. See Figure 7.
