Syntax MMEMory:WORKspace:IMPort[:USER]
<ProfileType>,<"SourcePath">,<"RelativeTargetPath">
Input
Parameters
<ProfileType>: Specify jitter sweep or spread spectrum clocking profile
type or SPProfile.
<“SourcePath”>: Specify the absolute source path of file to be imported.
<“RelativeTargetPath”>: Specify a current setting or a shared (common)
storage location.
Description An arbitrary profile waveform file can be imported for generating jitter
sweep or spread spectrum clocking. Three arguments have to be specified:
The first one is the profile type JSPRofile | SSCProfile | SPProfile,
second one is the absolute source path of the file to be imported,
third one is a relative target path "current:…" addresses the current setting
and "shared: …" addresses a location in the storage that is common for all
user settings.
For jitter sweep files, the file extension "…jcs" has to be used and for
spread spectrum clocking the extension "…txt".
S-parameter profiles containing1- to 9-port components are supported.
The file extension "…s1p…s9p" can be used.
