Estimating the Duration of a Measurement with the FLS 106
19.3
Scanner
Number of Measuring Points
19.3.1
The duration of a measurement with the scanner increases linearly with the number of the
measuring points set.
Travel Distance
19.3.2
The smaller the distance between two neighbouring measuring points, the less time it takes to
travel between the measuring points.
Sweep Time
19.3.3
The larger the sweep time of the spectrum analyzer, the longer the measurement takes. It should
be noted that the sweep time alone is a multiple of the time required for travelling and transmitting
the measurement curve. This may take several seconds, especially if the span to be shown is large
and the resolution bandwidth is small, it may take several seconds. In addition, the sweep time is
multiplied by the value set at "Average Count" if "Average" is used.
Transmission Time
19.3.4
The time for the transmission of a measurement curve from the spectrum analyzer to the PC
mainly depends on which transmission interface is used. The transmission of a measurement
curve with 1,000 measuring points only takes a few milliseconds if a GPIB and VXI is used. In
contrast, the transmission takes several seconds if the RS232 interface with a small baud rate is
used.
Storage Requirements for the Measurement
19.4
Both the hard-disk storage and the RAM storage must be large enough for storing and showing a
scan's measurement results.
The storage requirements depend on the:
- number of measuring points in the space
- number of points per trace
- vertical resolution of the spectrum analyzer
Please note that when using Windows as a 32-bit operating system, no more than 2 GB of RAM
storage is assigned to the individual programs.
