5 Creating and Downloading User-Data Files

Overview

User data is a generic term for various data types created by the user and stored in the

signal generator. This includes the following data (file) types:

Bit This file type lets the user download payload data for use in streaming or framed

signals. It lets the user determine how many bits in the file the signal generator uses.

Binary This file type provides payload data for use in streaming or framed signals. It

differs from the bit file type in that you cannot specify a set number of bits. Instead the

signal generator uses all bits in the file for streaming data and all bits that fill a frame for

framed data. If there are not enough bits to fill a frame, the signal generator truncates the

data and repeats the file from the beginning.

PRAM With this file type, the user provides the payload data along with the bits to

control signal attributes such as bursting. This file type is available for only the real-time

Custom and TDMA modulation formats.

FIR Filter This file type stores user created custom filters.

State This file type lets the user store signal generator settings, which can be recalled.

This provides a quick method for reconfiguring the signal generator when switching

between different signal setups.

User Flatness Correction This file type lets the user store amplitude corrections for

frequency.
