SMA Probe Head Atten/Offset Calibration
1 Referring to Figure 90 below, perform the following steps:
a Connect the SMA to BNC adaptor to one of the SMA connectors of
the deskew fixture or SMA (f) to SMA (f) adapter.
b Connect the 50 ohm terminator to the center SMA connector of the
SMA probe head.
c Connect the other end of the deskew fixture or SMA (f) to SMA (f)
adapter to one of the SMA connectors of the SMA probe head.
d Connect the BNC connector of the SMA to BNC adaptor to the Aux
Out on the front panel of the Infiniium oscilloscope.
e Connect the positive (+) side of the InfiniiMax probe amp to the GPO
(SMP) connector of the SMA probe head whose path is connected to

NOTE
Each probe is calibrated to the oscilloscope channel to which it is connected. Do not switch
probes between channels or other oscilloscopes, or it will be necessary to calibrate them
again. It is recommended that the probes are labeled with the channel on which they were
calibrated.
