ARBITRARY WAVEFORMS
In-built Arbitrary Waveforms
Sinc, Exponential Rise, Logarithmic Rise, DC, Positive and Negative Ramps and Square
waveforms are built-in and always present.
Additional waveforms are supplied on disc (Cardiac, Gaussian, Exponential Fall, Logarithmic
Fall).
User defined Arbitrary Waveforms
Up to 4 additional or user defined waveforms may be stored in non-volatile memory.
Waveforms can be defined by downloading of waveform data via USB memory stick, remote
interfaces, or editing via the instrument’s front panel.
Waveform Size: 2 points to 131072 points (128k).
Memory Size: Up to 4 waveforms of up to 64k points, or 2 waveforms of up to 128k
points, (or 2 of 64k points plus 1 of 128k points).
External Storage: Up to 1,000 waveforms per USB memory stick.
Vertical Resolution: 14 bits
Frequency Range: 1µHz to 10MHz (TG2511 - 1µHz to 6MHz)
Resolution: 1µHz , 14 digits
Output Level: 10mVp-p to 10Vpp into 50 W
Sampling rate: 125MS/s
Output Filter: Selects between 50MHz Elliptic or 20MHz Bessel filter depending on
the waveform.
Arbitrary Waveform Creation and Editing
Waveform creation and editing is provided within the generator including point insertion, line
drawing and interpolation.
WAVEFORM MANAGER PLUS
Both generators are supplied with Waveform Manager Plus. This Windows* based software
provides a sophisticated tool set for the creation, editing and management of arbitrary
waveforms. The waveforms can be transferred to the generator either using a USB memory
stick, or by the digital interfaces.
