The default closed channels are 1 and 5 — the lowest number in each bank. At power-up, the lowest numbered channel in each
bank will always be closed. If using a saved setup that calls for another channel to be closed, the card will be switched to that
channel but only after the ﬁrmware has ﬁnished "waking up." Therefore, the lowest channel will ALWAYS be closed for at
least a brief time at power-up. The user needs to verify that nothing is connected to the lowest channel in each bank that could
The connectors on the card are standard SMA type connectors. When making or breaking connections, use a torque wrench to
produce mating torque of 0.9 N•m (8in•lbs).
Use a box-spanner torque wrench similar to Suhner Type 74 Z-1-0-21, Identiﬁcation number
543130. This wrench is for SMA connectors with a 1.00 N•m torque with 8.0mm (0.315 in.) across
Model 7711/7712 channel connections
Do not touch live RF (radio frequency) conductors, even at low voltages! RF behaves
differently than DC or low frequency AC. Low voltage RF can cause severe burns. RF
signals spread out over body areas generating substantial currents at the points of
contact with RF conductors.
Make all connections using correct wire size. If BNC connections are required, use the SMA to BNC adapter cables (see
