5.7.2 Screen Image Files
A screen image file represents a "snapshot" of the whole of the screen excluding the key area.
A screen file can be recalled in a similar way to an image on a digital camera, whilst sweeping
of the spectrum analyser is suspended (Paused). It can also be exported to a PC and printed
for documentation purposes.
Screen files are indexed colour bitmaps of about 50 kilobytes in size. Within the instrument
they use an 8.3 naming format with the extension .BMP A maximum of 999 files can be stored
within the internal memory of the instrument. Screen files can be copied to a PC and imported
into photo viewing and editing programs such as Windows Picture and Fax Viewer, Paint,
Photoshop etc.
Image files can also be displayed using PSA-Manager software which is supplied with
Option U01.
5.7.3 Setup Files
A setup file records the complete state of the instrument at the point that it was saved, including
marker positions, the view trace and the reference trace.
Setup files are small being a few kilobytes each. Within the instrument they use an 8.3 naming
format with the extension .SET. A maximum of 999 files can be stored within the internal
memory of the instrument. Setup files can be copied to a memory stick or onto a PC for backup
purposes, but have no function outside of the instrument.
5.7.4 Other File Types
When Option U01 is fitted (see section 6) three other file types can exist. These are
Compensation Table files, Limit Pattern files, and Logging files. Details of the functions are
provided within section 6 of the manual.
5.7.4.1 Compensation Tables
Compensation tables are normalised files of amplitude versus frequency which must be created
outside of the instrument using PSA-Manager software. They are a few kilobytes in size.
They files have the extension .CMP and are located in the folder named TABLES. Files can be
transferred using either a USB Flash drive, or by direct connection to the USB port of a PC.
5.7.4.2 Limit Pattern Tables
Limit pattern tables are normalised files of amplitude versus frequency which must be created
outside of the instrument using PSA-Manager software. They are a few kilobytes in size.
They have the extension .CSV and are located in the folder named TABLES. Files can be
transferred using either a USB Flash drive, or by direct connection to the USB port of a PC.
5.7.4.3 Logging Files
Logging Files record multiple entries of sweep data in response to a variety of trigger signals.
They can contain several types of data and are variable in size up to tens of megabytes. They
have the extension .LOG and are located in the folder named LOGS.
The files are created within the instrument and must be transferred to a PC for analysis using
PSA-Manager software. Files can be transferred using either a USB Flash drive, or by direct
connection to the USB port of a PC.
