Used to measure
and calibrate precision
devices (e.g., Terminations,
Attenuators, and Adapters).
Requires Offset
SWR Autotester.
Mathematically
computes
the return loss
from the raw
ripple data.
Enter approximate length
of transmission line in
meters or feet. Meter or feet
selection is accessed
under SYSTEM SETUP
after pressing the
SYSTEM MENU key.
Select the number of
data points. The 1024
selection provides better
distance resolution in the
final plot but requires longer
calibration and measurement
times. You might run the first
test using 256 data points,
then rerun the measurement
using a higher resolution if
you determine from the plot
that it is needed.
Lets you zoom in on
an area of interest.
Enter the points (in feet
or meters) where you
want to start and stop
the zoom action. If the
range is altered, the
STOP distance will
change accordingly.
Choose the type of side
lobe reduction algorithm
that the 541XXA will use
to process the DTF
measurement data.
This process suppresses
sidelobe data that may
mask small reflections.
Offsets return loss by fixed
amounts to account for
known losses (e.g. attenuators)

To delete a previously entered coaxial or waveguide entry,
1. Highlight the entry, then press the Select key.
2. Choose the ENTER NEW COAX or ENTER NEW WAVEGUIDE option.
3. Highlight the name in the next entry to appear and press Clear key.
NOTE:
Use this selection when
transmission is a hydrid
consisting of waveguide
with a coax input.
Frequencies must
be entered such that
cutoff Freq is less
than F1 Freq and F1
is less than F2 Freq
(cutoff Freq <F1<F2)
at all times. Also the
F2-to-cutoff Freq
range must be within
the range of the
541XXA model.
Alternative menus depending on selection of Medium type
NOTE:
In addition to being able to add and
edit the lists of waveguide and coaxial
transmission lines, you may also access
these files directly and make changes.
These files (COAX.LST and WVGD.LST)
are available in ASCII text format on the
541XXA System Diskette. They can be
edited with DOS text editor, such as
EDIT.COM that is available from within
MS-DOS 5.0 and above. Do not edit the
files using a word processor. It will
introduce coding that will corrupt
these two *.LST files.
Fixed types may not
be altered; however,
they may be used to
create a new type
(e.g. , POLYE1).
This new type may
then be modified.
Limits the frequencies used when
performing DTF measurements,
e.g., to avoid specific bands.
This may restrict the available
display resolution at small
distance ranges.
NOTE
To modify a frequency range, press
the Frequency key after selecting DTF.
This displays the "FREQUENCY MENU
DTF MODE" menu options.
