Meeting ID: JFDBP6
Meeting Key: m&R'QJw|4
Agenda:
- Review of Touchstone(R)2 draft 5
- Example of S-parameter Shorting under IIRD9
========================================================================
No opens were raised.
During review of the latest revision of the Touchstone(R) update draft,
several recommendations were made:
- (Radek) revise the noise parameters according to the following
summary:
x1 is a frequency and is formatted from the options line
x2, x3 are the complex form of the source reflection coefficient and
are not normalized; they are not formated by the option line
in version 1.0 files. x2 is a magnitude (not R or dB)
x4 is in degrees
x5 has normalization per version 1.0 options line but should not
be normalized in version 2.0
- (Bob, John A.) reorganize the document to make the difference
between
version 1.0 and 2.0 rules more clear
- (Radek) provide more version 2.0 examples
- (Radek) remove G, H mentions for 1-port and n-port formats
- (Radek) explain how empty options lines are interpreted
- (John M.) use | instead of / character to separate options
- (Radek) use a non-1 option R in an example
- (Radek) use a non-normalized example
- (Radek) explain the number of items/line or line length requirements
in
version 2.0. Clarify that the parser reads groups of 2N+1
elements,
where N is the number of ports. End-of-line characters
therefore
don't matter
- (Radek) Replace "matrix format" with "matric row-wise entry"
Michael will implement these changes.
ARs
-----
Sam - provide a simple drawing of "virtual reference" case
Michael - update IIRD9 draft with changes for final review next time -
DONE
Team Objectives:
1) complete ICM-IBIS linking BIRD and any associated changes to the
ICM specification
2) update the ICM specification, if needed, to clarify the mapping of
ICM nodes to S-parameter ports
3) complete a specification for "Touchstone Plus" or similar
industry-standard definition for Touchstone-like files, to include
complex impedance references, removal of limits on the maximum number
of ports and per-port impedance references
