Both generators offer DDS generated
arbitrary waveforms capability.
A number of standard waveforms are
included, and up to four user defined arbitrary
waveforms can be stored in the instrument at any one
14 bits, 128k words, 125MS/s
Waveforms have a vertical resolution of 14 bits (16,384
amplitude levels). Waveforms can be created using
between 2 and 131,072 points (128k).
The sampling rate is 125MHz and DDS techniques are used
to provide any repetition rate between 1uHz and 10MHz
(TG501xA) or 6MHz (TG251xA)
with up to 14 digits of frequency resolution.
Internal and External Waveform Storage
Up to four user defined waveforms totalling up to 256k
words can be stored within the permanent internal memory
of the instrument.
However, a front
mounted USB port enables external Flash memory storage of up to
1000 waveforms of any size.
memory stick also provides a quick and convenient method
for transferring waveform files to and from a PC.
It can also be used for storing instrument set-ups.
complex waveforms are provided both built-in to the
instrument and for loading into the user defined
These include sin(x)/x, exponential
rise and fall, logarithmic rise and fall, gaussian,
lorentz, haversine and cardiac waveforms.
This waveform (sine with 35% third
was created using Waveform Manager Plus.
The display shows an approximation
of any arbitrary waveform loaded.
Local arbitrary waveforms can be loaded from
a USB flash disk which can store up to 1,000
waveforms. Waveform names are maintained
and can be edited within the generator
Pre-built complex waveform such as
sin(x)/x are built-in to the instrument.
Waveform Manager Plus is
a Windows based program for waveform
creation and editing.
