Creating and Downloading User-Data Files

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

Minimum File Size

A PRAM file requires a minimum of 60 bytes to create a signal. If the downloaded file contains less than 60 bytes, the signal generator replicates the file until the file size meets the 60 byte minimum. This replication process occurs after you select the file and turn the modulation format on. The following example shows this process using a downloaded 14- byte file:

During the file download, the 14 bytes are translated into 56 bytes (fourteen 32- bit words). 14 bytes ⋅ 4 = 56 bytes

File size increases by a factor of 4

After selecting and turning the format on, the signal generator replicates the file contents to create the 60 byte minimum file size

60 bytes / 14 bytes = 4.29 file replications

The signal generator rounds this real value up to the next highest integer. In this example, the signal generator replicates the fourteen 32- bit words (56 bytes) by a factor of 5, which makes the final file size 280 bytes. This equates to a 70 byte file.

14 bytes ⋅ 5 = 70 bytes

70 + [(70 ⋅ 24) / 8] = 280 bytes

Or

56 bytes ⋅ 5 = 280 bytes

File size increases by a factor of 5

SCPI Command for a List Format Download

Using the list format, enter the data in the command line using comma- separated decimal values. This file type takes longer to download because the signal generator must 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.
