Higher Frequencies
The TG5011 significantly out-performs other
generators in its price range by offering both sine and
square waves up to 50MHz. The lower
cost TG2511 is limited to 25MHz.
Waveform Quality The TG5011 and
TG2511 generate high purity sine waves with low harmonic
distortion and low phase noise.
Square waves have a rise time of below 8ns (13ns on
TG2511) and low
overshoot. Variable symmetry can be used up to 25MHz,
although the Pulse Function is more appropriate for wide
duty cycle waveforms.
Triangle and Ramp
High quality triangle and variable symmetry ramp
waveforms are available up to 500kHz (TG5011) or 250kHz
(TG2511).
These waveforms are also available at higher frequencies
via the arbitrary function but without symmetry
adjustment and with poorer waveform quality as the
frequency increases.
Exceptional frequency precision The
frequency of these waveforms can be set with up to 14
digits or one micro hertz of resolution.
The DDS based frequency generation system uses a TCXO
timebase oscillator with a stability of 1ppm.
VLF generation The high resolution of
the DDS system means that very low frequencies can be
set. For example, a frequency of
around 1mHz could be set with a resolution of 0.1% and a
stability of 1ppm |
