Recording Options Setup
When a device is connected, click on the double‐arrow icon
DIMM speed of the device. The application automatically inspects the device and displays
its speed, as long as the Host Under Test (HUT) is active.
If users select combinations in the Memory Controller settings which are not specified by
JEDEC specification for the appropriate Speed Bin, the application will display an error in
Red for the CL (nCK) and/or CWL (nCK) values with an exclamation mark (!) (see
Figure 2.17 on page 51). In this case, the analyzer will not enable the refresh button for
the timing violation triggers. The software will populate the Timing table with the last
valid set of timing values. The user may modify the individual timing values manually as
desired.
Note:
If operating the analyzer with invalid memory controller parameters, the analyzer software will
capture normally but may flag numerous timing violations.
