Table 8-4 Binary File Type Commands

Command		Command Syntax
Type

Query		:MEM:DATA? "bin:file_name"
		This returns information on the named file: <bit_count>,<block_data>.
		Within the context of a program, this query extracts the user file, provided it was
		download with the proper command.

Query		:MEM:CAT:BIN?
		This lists all of the files in the bit file directory and shows the remaining
		non- volatile memory:
		<bytes used by bit files>,<available non-volatile memory>,<"file_names">

a. See “FTP Procedures” on page 303.

There are three ways to format the file name, which must also include the file path:

•"BIN:file_name"

•"file_name@BIN"

•"/user/BIN/file_name"

Command Syntax Example

The following command downloads a file that contains 34 bytes:

:MEM:DATA "BIN:new_file",#2347^%S!4&07#8g*Y9@7.?:*Ru[+@y3#_^,>l

After execution of this command, the signal generator creates a file in the Binary (Bin) directory (memory catalog) named “new_file” that contains 34 bytes.

For information on downloading block data, see “Downloading User Files” on page 296.

Selecting a Downloaded User File as the Data Source

This section describes how to format SCPI commands for selecting a user file using commands from the GSM and Custom modulation formats. While the commands shown come from only two formats, the concept remains the same when making the data selection for any of the other real- time modulation formats that accept user data. To find the data selection commands for both framed and unframed data for the different modulation formats, see the signal generator’s SCPI Command Reference.

1.For TDMA formats, select either framed or unframed data:

:RADio:GSM:BURSt ONOFF10

ON(1) = framed

OFF(0) = unframed

2.Select the user file:
