VIA
DIRECTOR
Version 1.09
VIA Director provides chart plotting
and archiving of
SWR, Return Loss (RL), Impedance, Resistance, Reactance, Phase Angle
and
remote analyzer commanding
written for use with the
AEA Wireless, Inc.
CIA-HF and VIA-HF analyzers.
VIA Director Features:
SWR, Return Loss (RL), Impedance, Resistance, Reactance,
and Phase Angle:
• The VIA Director is used to control the AEA CIA-HF and VIA-HF analyzers.
These analyzers are capable of computing SWR, Return Loss (RL), Impedance, Resistance,
Reactance, and Phase Angle for any given frequency within the range of the analyser.
The VIA Director is used to retrieve these values from the analyzer, visually
display these values to the user, and archive the data.
Analyze an entire frequency band or just a single
frequency:
• For frequency band analysis, select the start and end frequencies, and
then select a step size. As the data values are being calculated, a plot will
appear in the Active Chart Plotting window. The individual data values; SWR,
return loss, impedance, resistance, and reactance, are accessible through a separate
scrolling data list window.
• For single frequency analysis, just enter a frequency. The data values
are displayed in the appropriate fields within this window.
• The Active Chart Plotting window contains several “tabs” used
to display individual data (SWR, return loss, impedance, resistance, and reactance)
waveforms. The window can be easily resized to take advantage of your monitor
size and resolution.
• A Comparison tab within the Active Chart Plotting window lets your overlay
the various data waveforms for easy visual comparison.
• A Smith Chart tab is also available.
Command the analyze remotely:
• Change an analyzer's width setting using the application's zoom in/out
function.
• Set the step size to 1kHz, 5kHz, 10kHz, 20kHz, 50kHz, 100kHz, 200kHz,
or 500kHz, depending upon the analyzer model selected.
• Step the analyzer center frequency up or down based upon the step size
currently set.
• Power on or off the analyzer.
• An Analyzer Control window simulates the front panel of the analyzer.
Most of the analyzers front panel functionality is available via the Analyzer
Control window.
Manipulate multiple charts:
• Display up to fifteen chart plots at one time. This feature allows easy
comparison of different "runs" of a frequency analysis, especially
handy during antenna tuning. Any or all of the fifteen plots can be selectively
turned on or off. You may also find this useful for comparing historical data
for a particular antenna. An analysis can be performed and the data saved for
later retrieval. At some later date, another analysis can be performed on the
same antenna. The previous analysis can be reloaded into the VIA Director. These
two chart plots can then be “overlaid” to check for any changes in
antenna performance/characteristics.
• Clear any one of the fifteen charts with a single button press. This
allows you to start again from scratch.
• Designate any one of the fifteen charts to be the "Active" chart.
The active chart is the only chart changed during a frequency band analysis;
the “Non-Active” charts will be unaffected. To differentiate between
the plots, the line width of the active chart is displayed slightly thicker than
the other lines.
• Zoom and pan within the chart plotting area.
• Display the individual data values, called labels, for the chart plots
within the plotting area.
• Enter a title to describe the chart, with or without a date and/or time.
• Quickly update the date/time for a chart.
• Select the background color of the chart plotting area.
• Turn on/off the background color gradient for the chart plotting area.
• View chart in 3D mode, handy for viewing slight differences between similar
charts. This feature will shift each chart slightly to the right. The data values
for each chart remain unchanged.
Create charts manually:
• Can't get a PC near your antenna during analysis? Data can be recorded
during your analysis and then, at a later time, manually entered using the VIA
Director to create a chart plot of your data.
Document charts:
• Print the chart plotting area to your printer. A printer setup facility
is also included.
• Save the chart plotting area as a bitmap, meta, or enhanced meta file--useful
for historical storage and incorporation into end user reports or documents.
• Save the active chart to a file for retrieval by the VIA Director at
a later date.
• View or Print a report of the active chart's raw data values.
• Export the chart data as a comma delimited text file allowing, for example,
import into a speadsheet for further analysis.
