combination of grooves, external threads and a coaxial interface
with a 2.92 mm airline geometry.

The second connector half is the connector saver. It has a similar
interface on one end, with spring-biased inner and outer contacts.
The connector saver has projections which interlock with slots on the
mounted connector and a coupling nut which secures the two halves;
resulting in a non-rotational, torque independent electrical connection. The
spring-biased inner and outer contacts eliminate the need for specifying
proof torque and no tools are required to mate or un-mate the connection.
The connector saver is easily field replaceable, should damage occur,
making it a more field reliable system. The 2.92 mm connector savers
operate mode free well beyond 36 GHz.
2.4 mm Interface
LabMaster 945MZi-A Master Acquisition Modules and 945SZi-A Slave
Acquisition Modules use the 2.4 mm interface 25 - 45 GHz inputs on
channel 3, input B. This interface consists of a precision connector and a
LEMO power and communication connector. It offers 50 Ω input
impedance only.
The 2.4 mm high-bandwidth electrical paths are comprised of two
connector halves/subassemblies which have a common mating interface:

The first connector half is mounted onto the oscilloscope
connector panel. The outer end of this connector has a
combination of grooves, external threads and a coaxial interface
with a 2.4 mm airline geometry.

The second connector half is the connector saver. It has a similar
interface on one end, with spring-biased inner and outer contacts.
The connector saver has projections which interlock with slots on the
mounted connector and a coupling nut which secures the two halves;
resulting in a non-rotational, torque independent electrical connection. The
spring-biased inner and outer contacts eliminate the need for specifying
proof torque and no tools are required to mate or un-mate the connection.
The connector saver is easily field replaceable, should damage occur,
making it a more field reliable system. The 2.4 mm connector saver
operates mode free well beyond 45 GHz.
