Agilent X-Series Signal Generators SCPI Command Reference 131
System Commands
Memory Subsystem (:MEMory)
Pattern Ram files are binary files downloaded directly into waveform memory as an array of bytes.
Each byte specifies a data bit (LSB 0), a burst bit (BIT 2), and an Event 1 output bit (BIT 6). Refer
to the Programming Guide for more information on pattern RAM downloading.
Example
:MEM:DATA:PRAM:FILE:LIST "Pram_Data", 85,21,21,20,20,100
The preceding example downloads PRAM data, in list format, to a file named Pram_Data in the signal
generator’s volatile memory (WFM1).
Range
0–255
Remarks Refer to “File Name Variables” on page 13 for information on the file name syntax.
:DATA:SHAPe
Supported N5172B with Option 653 or 655, N5182B with Option 656 or 657
:MEMory:DATA:SHAPe "<file_name>",<rise_pnts>,<rp0>,<rp1>,...<fall_points>,<fp0>,
<fp1>,...<fp(n)>
:MEMory:DATA:SHAPe? "<file_name>"
This command loads a burst shape file into the signal generator’s non–volatile memory (NVWFM).
"<file_name>" This variable names the destination file and directory path.
rise_pnts This variable indicates the number of rise points used to describe the burst shape
rising slope.
rp0,...rp(n) This variable defines each successive rise point, where 0 is no power and 1 is
full power.
fall_points This variable indicates the number of fall points used to describe the burst shape
falling slope.
fp0,...fp(n) This variable defines each successive fall point, where 1 is full power and 0 is no
power.
Refer to the Programming Guide for more information on downloading and using files.
Example
:MEM:DATA:SHAP "Shape_File",6,0,0.2,0.4,0.6,0.8,1.0,2,0.5,0
The preceding example loads shape data to a file named Shape_File in the signal generator’s
•
"Pram_Data" Pram_Data is the file name. PRAM files are saved
to the signal generator’s volatile memory (WFM1).
• 85 The first 8- bit integer value
• 21,21,20,20,100 Subsequent 8- bit integer values.
