Chapter 2: Probing and Selecting the Sampling Mode
Probing the Device Under Test
Using the E5380A Mictor-Compatible Probe
The E5380A MICTOR-compatible probe has a MICTOR connector end.
If you have a device under test with connectors designed for the
Agilent E5346A high-density probe adapter, you can also use the
E5380A probe.
However, the lower bandwidth of the E5380A probe limits the
maximum state speed of the logic analyzer to 600 Mbits/second.
The minimum input signal amplitude required by the E5380A probe is
300 mV.
The probe matches two 17-channel probe cables to a single-ended 38
pin MICTOR connector.
Mechanical
Considerations
Each E5380A probe requires a MICTOR connector and support shroud
built into the device under test.
You can order a probing connector kit, which contains five MICTOR
connectors and five support shrouds, using the Agilent part numbers:
• E5346-68701 for PC board thicknesses up to 0.062 in.
• E5346-68702 for PC board thicknesses from 0.062 to 0.125 in.
You can order MICTOR connectors separately using the Agilent part
number:
• 1252-7431 (or AMP part #2-767004-2)
You can order support shrouds separately using the Agilent part
numbers:
• E5346-44701 for PC board thicknesses up to 0.062 in.
• E5346-44704 for PC board thicknesses from 0.062 to 0.125 in.
• E5346-44703 for PC board thicknesses from 0.125 to 0.70 in.
Electrical
Considerations
All inputs on the E5380A MICTOR-compatible probe are single-ended.
The E5380A probe does not have a threshold reference voltage input.
When using the E5380A probe, the logic threshold voltage is adjusted
in the user interface.
