5. N5380B SMA Head
The N5380B SMA probe head provides the highest
bandwidth for connecting to SMA connectors. The
input resistance is 50Ω on both inputs. A shorting cap
connects one side of both resistances to ground. For
applications that require the resistances to be
referenced to a voltage other than ground, the shorting
cap can be removed and a dc voltage can be applied.
The E2695A 8 GHz SMA head for InifiniiMax I probe amplifiers was discontinued in December
N OT E
2013 and replaced by the N5380B 12 GHz SMA head.

Disconnecting the N5380B
When disconnecting a probe amplifier from the N5380B SMA probe head, grasp
the probe amplifier as shown in
from the SMA probe head without any rocking (either side-to-side or
up-and-down).
Pulling on the probe amplifier cable or strain relief, or rocking the probe amplifier to
CAUTION
remove it, may damage the probe head or probe amplifier.
