Creating and Downloading User-Data Files

Pattern RAM (PRAM) Data Downloads (E4438C and E8267D)

Command Syntax

:MEMory:DATA:PRAM:FILE:LIST <"file_name">,<uint8>[,<uint8>,<...>]

uint8

The decimal equivalent of an unsigned 8- bit integer value. For a list of usable

 

decimal values and their meaning with respect to the generated signal, see Table

 

8- 6 on page 312.

Command Syntax Example

The following example, when executed, creates a new file in volatile (waveform) memory with the following attributes:

•creates a file named new_file

•outputs a single pulse at the EVENT 1 connector

•bursts the data pattern 1100 seven times over 28 bytes

•transmits 32 nonbursted bytes

•resets the data pattern so it starts again

:MEMory:DATA:PRAM:FILE:LIST <"new_file">,85,21,20,20,21,21,20,20,21,21,20,20,21,21, 20,20,21,21,20,20,21,21,20,20,21,21,20,20,16,16,16,16,16,16,16,16,16,16,16,16,16,16, 16,16,16,16,16,16,16,16,16,16,16,16,16,16,16,16,16,144

The following list defines the meaning of the different bytes seen in the command line:

85Send a pulse to the EVENT 1 output, and burst the signal with a data bit of 1.

21Burst the signal with a data bit of 1.

20Burst the signal with a data bit of 0.

16Do not burst the signal (RF output off), and set the data bit to 0.

144Reset the data pattern, do not burst the signal (RF output off), and set the data bit to 0.

SCPI Command for a Block Data Download

The IEEE standard 488.2- 1992 section 7.7.6 defines block data. The signal generator is able to download block data significantly faster than list formatted data (see page 314), because it does not have to parse the data. When creating the data, remember that the signal generator requires a minimum of 60 bytes. For more information on file size limits, see “PRAM File Size” on page 313.

Command Syntax

:MEMory:DATA:PRAM:FILE:BLOCk <"file_name">,<blockdata>
