Minimum Hardware
Module quantity considerations
The following table provides examples of general guidelines for the number of U4164A modules
required for a few example applications. Refer to the requirements of your specific devices,
interposers and probes to determine the requirements for your application.
DUT configuration
U4164A module requirements
General purpose measurement requiring a given
number of channels on a single time base
DDR4 DIMM Interposer, > 2.5 Gb/s data rates,
capture all ADD/CMD/data
Each U4164A has 136 channels. A maximum of three
U4164As can be combined for 408 channels
Three U4164A modules, each with Option 02G
DDR2/3/4, 64-bit data, ≤ 2.5 Gb/s data rates,
capture all ADD/CMD/data (read and write)
LPDDR1/2/3/4, ≤ 2.5 Gb/s data rates
LPDDR4, > 2.5 Gb/s data rates
Two U4164A modules, each with Option 01G
One U4164A module
May require up to three U4164A modules (depends
on the number of data signals probed and the probing
layout) 1
1. To determine the number of channels, and therefore the number of modules, required for a DDR/LPDDR
memory system operating at > 2.5 Gb/s, allocate four U4164A channels for each DDR/LPDDR memory DQ
captured.
