Output switcher

Operating Manual 1120.8610.14 - 0

The output switcher has a special feature: After channel number

–1 has been entered,

the output switcher can through-connect all signal paths in busbar

, except the path

selected for busbar

. This setting allows, for example, worst-case crosstalk

measurements, in which the coupled residual signal is measured in one channel and
all other channels are driven.
