124 Agilent X-Series Signal Generators SCPI Command Reference
System Commands
Memory Subsystem (:MEMory)
The preceding example downloads and appends the data, Y9oL, to an existing file named IQ_Data
stored in the signal generator’s non–volatile memory (NVWFM).
Remarks Refer to File Name Variables for information on the file name syntax.
:DATA:BIT
Supported N5172B with Option 653 or 655, N5182B with Option 656 or 657
:MEMory:DATA:BIT <"filename">,<bit_count>,<datablock>
:MEMory:DATA:BIT? <"filename">
This command loads bit data into signal generator memory using the <bit_count> and <datablock>
parameters and saves the data to a file designated by the <"filename"> variable. The query returns
the bit count, file length information, and the data.
<"filename"> This variable names the destination file and the directory path.
<bit_count> This number represents the number of bits in the data block.
<datablock> This parameter represents the data and file length parameters. The data in the file
is represented by the <datablock> variable. The file length parameters are used
by the signal generator for allocating memory.
Refer to the Programming Guide for more information on downloading and using files.
Example
:MEM:DATA:BIT "Test_Data",16,#12Qz
The preceding example downloads bit data to the file, Test_Data. The table below describes the
command parameters.

# This character indicates the beginning of the data block
1 Number of digits in the byte count
4 Byte count
Y9oL 4 bytes of data
• "Test_Data" Test_Data is the file name. The directory path is not
needed. The path "/USER/BIT/" is implied.
• 16
Number of bits in the data block
•
#12Qz
Data block
#
This character indicates the beginning of the data block
