Connection sequence specifies the open/close sequence of the relays when changing
from an existing connection to a new connection. You can specify the connection
sequence by using the [:ROUTe]:CONNection:SEQuence command described in
Chapter 7.
You can select one of the three connection sequences shown in Table 5-3 for each
card installed in the E5250A.
