Most active probes match probe to oscilloscope response
automatically using probe response data stored in an on-board
EEPROM. This ensures the best possible combined probe plus
oscilloscope channel frequency response without the need to
perform any de-embedding procedure.
Interfaces differ in bandwidth capabilities, so the interfaces contained on
your oscilloscope—and their exact location—depend on the bandwidth
rating of the oscilloscope model you purchased.
High-bandwidth interfaces ( 45 GHz and up) must be enabled by selecting
the appropriate Dual Bandwidth Interleave setting on the Timebase dialog
and the Input B setting on the Channel dialog.
ProBus Interface
LabMaster 10xxZi Acquisition Modules rated to 36 GHz use the ProBus
interface for AUX In and AUX Out connections. These connectors are
located on the front of the unit next to the channel inputs.
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.
2.92 mm Interface
All LabMaster 10xxZi Acquisition Modules use the 2.92 mm interface to
input signals up to 36 GHz on channels 1-4, input A. This interface consists
of a precision connector and a LEMO power and communication connector.
It offers 50 Ω input impedance only.
