SMA/SMP Lead Set
The SMA/SMP interconnect has two parts:
l
An interconnect “lead” which plugs into the amplifier module
l
Two cables (either SMA terminated or SMP terminated) which plug into the interconnect lead
and connect to female SMA or SMP connectors
SMA/SMP lead set
A network at the end of this interconnect lead, at the point where the SMA cables attach, attenuates
the signal for the correct scale factor as well as provides some response compensation. The SMA
input cables must always be used with the SMA interconnect lead. Calibration is not dependent on
these leads. However they are a matched pair, so individual cables should not be interchanged
between probes.
The SMA DC blocking adapters (supplied with the SMA interconnect lead) can be used to extend the
common mode or differential mode range by removing any DC component which exceeds the
range. This would most likely be a common mode component.
NOTE: The SMA input cables use the same connectors as in the interconnect leads and will
physically mate with the amplifier module. However, the system will not work properly in this
configuration. No damage to the probe or amplifier will occur. However maximum voltage to prevent
destruction will be much lower and the susceptibility to ESD is reduced.
