Creating and Downloading User–Data Files
Overview
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.
Prior to creating and downloading files, you need to take into consideration the
file size and the amount of remaining signal generator memory. For more
information, see “Signal Generator Memory” on page 321
