The LeCroy WavePro 700Zi series oscilloscopes with bandwidths of 4 to 6 GHz include universal ProBus/ProLink
probe interfaces. As shown in the following figure, each channel has a high bandwidth ProLink connector and a
50 /1 M ProBus connector.
Figure 3-6. A WavePro760 Zi showing the four sets of ProBus/ProLink probe interfaces. This oscilloscope
is compatible with all LeCroy probes.
This unique interface provides the user the greatest flexibility in probe selection in any oscilloscope. The ProLink
inputs provide a high integrity, high bandwidth interchangeable interface to SMA cables, LeCroy ProLink probes,
and accessories. ProLink is used for higher bandwidth probes.
The ProBus interface offers both 50 /1 M 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, differential probes. ProBus also includes sense rings for detecting passive probes. All scopes with
bandwidths over 4 GHz, except the WavePro 740Zi and760Zi, use 50 inputs and provide 1 M impedance by
means of external adapters.
The following figure shows a typical channel setup. The input selection is on the left hand side of the dialog box.
In this case the A input, the ProLink interface is selected. Each input selection has its own independent settings
for Probe attenuation, bandwidth and coupling.

Note : Input A (Upper) and B (Lower) refer to the two rows of input channels specifically available on WavePro
740 and 760Zi. WavePro 715, 725, and 735Zi all have only one row of input channels on the front panel, and
one corresponding selected input on the screen layout.
