Data Sheet

Further features with option U02
Option U02 is a firmware upgrade that increases the capabilities of the
PSA3605 or PSA6005 to include the following features (marked with *).
Automatic Measurements*
Automatic measurements
of Channel Power (CP),
Adjacent Channel Power
Ratio (ACR) and Occupied
Bandwidth (OBW) can be
performed.
Measurements can be
performed continuously or
in single-shot mode.
Limit patterns and limits comparator*
Limit lines and patterns can
be defined which can be
simply visual aids or create
automatic actions. Zone
restriction can be applied.
A single or dual line limits
comparator can be used to
generate audible warnings,
output signals, or to freeze
or log the trace.
Channel Markers *
Channel Marker List files are a special type of limit pattern file that
contain only vertical lines. They can be particularly useful for showing
channel position frequencies.
PSA-Manager provides
an editor that enables
them to be created by
simply entering a list of
frequencies. Each file can
contain up to 50 marker
lines.
Triggered sweep*
The standard sweep modes of continuous repeat and single shot can be
extended to include triggered sweeps from an external signal or internal
limits comparison.
High resolution Scan Mode*
The normal sweep mode of the analyzer collects and displays 271 points
of data across the span.
In Auto RBW mode the resolution bandwidth will be set to be appropriate
for this number of points, and can not be significantly improved upon
by setting a narrow RBW. Instead, the span must be reduced until the
desired resolution is obtained.
There are circumstances where it may be useful to observe a span at
much higher resolution than is possible using a normal sweep
.
Scan Mode is an entirely
different mode of operation
in which a narrow RBW can
be set resulting in a much
higher number of data
points being collected - up
to 210,000 points.
This data is written to a file,
the contents of which are
displayed in a compressed
form. Pan and zoom
functions allow any part of
the scan to be analyzed in
detail right down to one
pixel per point.
Once the scan is completed,
the data is written to the
display in both the graticule
window and an overview
area below as a data
envelope.
When the display is zoomed, the overview continues to show the whole
scan whilst indicating the section being shown within the graticule
window.
The marker can be used to rapidly pan the display to a new area.
At maximum zoom (271 points shown) the display returns to showing a
single data point per pixel, and the marker provides an amplitude readout
in addition to frequency.
Scan files can be saved in a similar way to trace files, and exported
as CSV data for use with PSA Manager or other third party analysis
programs.
Data Logging*
The PSA Series 5 can log results in response to a variety of stimuli. Data
is stored as files that can be transferred to a PC for analysis using PSA-
Manager software.
The data stored can be the
peak level, centre frequency
level, the whole trace, or
a bitmap screen image.
Each file can contain up to
25,000 entries.
The 1.8GB of internal memory enables vast amounts of data to be stored.
Logging entries can be created by an internal timer (adjustable from
seconds up to hours), the manual trigger key, the external trigger input,
or the limits comparator.
