15.2.1 Content and format of the pattern generator files
The pattern generator supports .bin or .csv file formats.
Content and format of the R&S*.csv files
The file's header have the following structure:
●
Bit rate [double]: the number of transmitted bits per second. The value is reflected
in the user interface.
●
High level [double]: the value is reflected in the user interface.
●
Mask [string of 8 characters made up of "X"/"1"/"0"] : defines how the output of the
pattern generator looks like. The following values are defined:
– 1' means that the pin output is always at high level
– 0' means that the pin output is always at low level (close to 0V)
– X means that the pin output varies according to the given pattern
●
Data sample format [HEX, BIN, OCT, DEC]: indicates how the samples are going
to be interpreted. Each sample is represented as 8bit value (corresponding to the
8bit pattern generator) considering the selected format.
Example: Sample format HEX
Format= HEX // Defines the format of the pattern values [HEX, DEC, BIN, OCT]
0F -> Data Sample 1
21 -> Data Sample 2
........
The samples are mapped on the 8 pins of the pattern generator as follows:
=> Pattern Samples are:
D7 D6 D5 D4 D3 D2 D1 D0
0 0 0 0 1 1 1 1
0 0 1 0 0 0 0 1
Example: .csv pattern generator file
R&S Pattern Generator File
Rate= 1000000 // Bit Rate [double]
HLevel= 1.5 // High Voltage Level [double]
Mask= X111000X // Masks the Pins to be used in the Pattern Generator
// [0 => always LOW, 1 => always HIGH, X/x => used in the Pattern]
Format= DEC // Defines the format of the pattern values [HEX, DEC, BIN, OCT]0
