Creating a Standard Gain Antenna Cal Denition
In-Depth Description of a Cal Denition
The example below is of a cal denition that contains one antenna denition. The top four
lines are the header for the entire le . These lines must only occur once , at the top of the le .
CITIFILE A.01.01
#NA VERSION HP8530A.01.00
#NAME ANTENNA_DEF
These three lines should be included exactly as shown. The rmware revision on line 2
\HP8530A.01.00" does not need to be changed if your HP 8530A has a later rmware revision.
Keeping line 2 exactly as shown above is acceptable . These lines are part of the le header .
#NA DEF_LABEL uWaveA.1
This line denes the title for the antenna calibration softkey . Y ou can change the label
\uW aveA.1" to any label you want, up to the limit of ten characters . This line is part of the le
header .
#NA STANDARD 1
This line starts dening the antenna denition. When creating several antenna denitions , the
number \1" should be incremented (2, 3, and so on) for each successive antenna denition.
\Creating a Cal Denition with Multiple Antenna Denitions" shows an example of this .
#NA STANDARD_LABEL SASGH-1.10
This denes the softkey label for this antenna denition. Y ou can change the label
\SASGH-1.10" to any label you want, up to a maximum of ten characters . It is recommended
the label be changed to reect the type and frequency range of the standard gain antenna.
VAR FREQ MAG 21
Enter the number of frequency points at the end of this line (where the number 21 is located
in this example). The rest of this line always stays the same .
DATA GAIN [1] DB
This line does not aect the antenna denition in any way , but we recommend you leave it in.
(Future rmware revisions may require this line .)
SEG LIST BEGIN
SEG 2000000000 4000000000 21
SEG LIST END
These three lines dene the start frequency , stop frequency , and the number of points (again).
Frequencies must be expressed in Hertz. Never change the rst or third line .
