Probe Operation
There are two basic operating modes for the P6467 probe that you can set by
jumpers J2 and J3, NORM and DIV2. The following sections describe the
operating modes and the clock distribution.
The NORM operating mode lets you acquire data synchronously and asynchro-
nously at speeds up to 100 MHz. The NORM mode acquires data in a similar
matter as the standard 92A96 probes. The main difference is that the P6467
probe does not have individual podlet connectors. A 30-pin connector is used to
connect to a mating connector on the system-under-test. You can connect the flex
cables to one of two mating connectors available from AMP Inc. The two
connectors and the pinout information is described in Appendix A: P6467
High-Speed Probe Adapter Input Connector.
When you use the probe in the NORM operating mode, the flex cable defined as
the Master Clock channel passes the signals from the probe to J200 (bottom two
connectors). Jumper J1 (MSTR CLK/EXT) must be in the MSTR CLK position.
You only need to connect one of the probe cables to either of the top two or
bottom two probe cable connectors.
The DIV2 mode (divide-by-two) operating mode lets you acquire synchronous
data at speeds greater than 100 MHz. If you choose to use the probe in the DIV2
mode, you must be aware of the following limitations of this operating mode:
H
Only synchronous acquisitions are allowed.
H
You can only use one clock signal with no clock or data qualifications.
H
Data is sampled only on the rising edge of the supplied clock.
