The template for component data fiIes is as follows:
! comment line
<data line>
. . .
where
!
indicates that ah following on this Iine is a comment
#
indicates that entries following on this Iine are parameters that are being
specified
frequency
units
parameter S for S-parameters
format DB for dI3 magnitude and angie in degrees
MA for linear magnitude and angle in degrees
RI for real and imaginary pair
Rn the reference impedance in ohms for the analyzer making the measurement
(R 50 or R 75)
The "format" above is selected by the current selection under the FORMAT menu. lb select the
DB format, the FORMAT must be LOG MAG. For MA, the FORMAT must be LIN MAG, and aII
other FORMAT selections wiIi output RI data. The S2P data wiII always represent the format
array data, including effects of electrical delay and port extensions A CITIfiIe wiII be saved at
the same time. lb be consistent with previous versions, the CITIfiIe data saved wiII represent
the DATA array (corrected data) without effects of electrical delay or port extensions.
Here is an S2P example fiie for an 11 point measurement of a 20 dB attenuator:
