Downloads Directly into Pattern RAM (PRAM)
Chapter 4 187
Via the remote interface:
For TDMA formats, send the following SCPI command:
[:SOURce]:RADio:<desired format>[:STATe]:ON
For custom modulation, send:[:SOURce]:RADio:CUSTom[:STATe]:ON
To adjust symbol rate, filtering, or other parameters, send the appropriate SCPI command.
SCPI Command to Download Data in Block Format
:MEMory:DATA:PRAM:BLOCk <datablock>
This command downloads the block-formatted data directly into pattern RAM.
Sample Command Line
A sample command line:
:MEMory:DATA:PRAM:BLOCk #ABC
#A the number of decimal digits to follow in B
B a decimal number specifying the number of data bytes in C
C the binary user file data
Example 1
:MEMory:DATA:PRAM:BLOCk #1912S407897
#1 defines the number of decimal digits to follow in “B”.
9 denotes how many bytes of data are to follow.
12S407897 is the ASCII representation of the data downloaded to the signal generator.
This variable is represented by C in the sample command line.
NOTE Not all binary values can be printed as ASCII characters. In fact, only ASCII
characters corresponding to decimal values 32 to 126 are printable keyboard
characters. The above example was chosen for simplicity. Typically, the binary
value corresponding to your 8-bit pattern is not printable.
Therefore, the program written to download and upload user files must
correctly convert between binary and the visible representation of the data
sequence.
