control for a wide range of probes with bandwidth ratings from 3 GHz to 20
GHz. The nature of the ProLink interface with its recessed BMA connector
means that an adapter must be connected to the ProLink interface to allow
SMA or 2.92/K connector terminated cables to be attached to the
oscilloscope channel. These adapters are normally provided with your
oscilloscope, and are described in ProLink Interface Adapters (on page 67).
ProBus Interface
LabMaster 9xxMZi-A Master Acquisition Modules rated to 20 GHz use the
ProBus interface for inputs up to 25 GHz on channels 1-4.
LabMaster 945MZi-A Master Acquisition Modules use the ProBus interface
for inputs up to 25 GHz on channels 1 and 4, input B.
The ProBus interface contains a 6-pin power and communication
connection and a BNC signal connection to the probe. It offers both 50 Ω/1
MΩ input impedance and provides probe power and control for a wide
range of probes such as high impedance passive probes, high impedance
active probes, current probes, high voltage probes, and differential probes.
ProBus also includes sense rings for detecting passive probes. The ProBus
interface may also have a BNC-terminated cable connected directly to it.
ProBus is based on a BNC connector and, depending on the exact BNC
connector used and the oscilloscope design, is rated for up to 4 GHz with
50 Ω coupling or up to 1 GHz for 1 MΩ coupling (depending on the exact
model purchase).
2.92 mm Interface
LabMaster 930SZi-A Slave Acquisition Modules use the 2.92 mm interface
for inputs up to 36 GHz on channels 2 and 3, input B.
LabMaster 945MZi-A Master Acquisition Modules and 945SZi-A Slave
Acquisition Modules use the 2.92 mm interface for inputs up to 36 GHz on
channel 2, input B.
This interface consists of a precision connector and a LEMO power and
communication connector. It offers 50 Ω input impedance only.
The 2.92 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
