LabMaster 10 Zi Oscilloscopes
The 2.92 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 2.92 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 saver
operates mode free well beyond 36 GHz.
1.85 mm Interface
LabMaster 10xxZi Acquisition Modules rated over 36 GHz use the 1.85mm
interface for 50-65 GHz inputs (channels 2 and 3, input B). This interface
consists of a precision V-male connector with a V-female to V-female barrel
adapter and a LEMO power and communication connector. It offers 50 Ω
input impedance only. The barrel adapter is easily field replaceable, should
damage occur.
The male connector is mounted onto the oscilloscope connector panel
when delivered. The female-female barrel adapter must be manually
attached before connecting cables.
