PNA Series Data-Based Cal Kit Editor


Information on the Data-Based Cal Kit Editor

This Calibration Kit Editor, now part of firmware A.04.06 and above, allows the creation of cal kits that include data-based standards. Data-based standards are described by a data list. A data-based standard should include a list of frequencies, the actual response for each s-parameter at each frequency and an estimate of the accuracy of the actual response to be used in determining the weighting factor used by expanded cal.

Currently, only one-port data-based devices are supported. Support for two-port devices will be added later. The download link is at the bottom of this page.

Preliminary #PNA keywords

The PNA currently does not recognize the following keywords (they are ignored). Future revisions will include the following keywords to allow the data-based standard to be completely defined by the CITIFILE.

#PNA Keyword table (Preliminary)
Statement Explanation
#PNA REV s #PNA Revision
#PNA STDTYPE s Calibration standard type
s can be DATA-BASED
#PNA STDREV s Standard revision
#PNA STDLABEL s Standard label
#PNA STDDESC s Standard description
#PNA STDFRQMIN f Min frequency for standard selection (may be different from range of use) (Hz)
#PNA STDFRQMAX f Max frequency for standard selection (may be different from range of use) (Hz)
#PNA STDNUMPORTS d Number of ports default 1
#PNA PINDEPTH d f1 f2 Indicates pin depth for coaxial connectors to allow for pin depth compensation to the model
d= port number
f1= value included in the model data (mm)
f2= actual value (mm)
#PNA DEFINECONNECTOR s1 f1 f2 s2 <f> Defines connector (NOT NEEDED IF PREDEFINED)
s1= connector ID
f1= minimum frequency (Hz)
f2= maximum frequency (Hz)
s2= connector type can be
COAX, WAVEGUIDE,
<f>
is an optional list of parameters to specify values needed for connector type.
<f> is ignored for COAX
<f> the first element is cutoff frequency for WAVEGUIDE
<f> to be determined for other types
#PNA CONNECTOR d s1 s2 Connector assignment
d= port number
s1= connector ID corresponding to predefined ID or
one defined by
DEFINECONNECTOR
s2
= connector sex can be MALE, FEMALE, NONE
#PNA COVERAGEFACTOR f Coverage factor for weighting default f =1



This program can be installed on either a PC or the PNA itself.

The regular CalKit Editor, which is available on the Applications page, now includes this capability. It is also part of the A.04.06 firmware which was released in December 2003.
