These Product Tours are just a structured sequence of web pages. Click the ► button to step through them.
The navigation buttons have the following functions:
|◄ takes you back to the beginning of the current tour
◄ is the same as your browser back button
▲ takes you up a level in the hierarchy
► steps forward to the next page
The drop-lists give another way of accessing the same pages
shows and hides a map of the structure of the tour with links to each page.
expands the tour into its own window (only visible when embedded in another page.)
TG251xA and TG501xA Series Tour Map
TGxA Series Function Generators: phase locking generators
each generator can be set to be a Master
or a Slave for phase locking
External Frequency Reference
The generators use a high quality
TCXO crystal as the internal frequency reference.
If a higher accuracy or stability is
required, an external 10MHz reference signal can be
applied to the Reference Clock input.
Phase Locking Two Generators (or more)
Two generators can be synchronized together to provide
outputs at the same frequency (or at harmonics) and with
a phase difference.
The amplitude and phase of these
outputs can also be modulated providing the capability
to perform QAM and QPSK respectively.
Any waveform other than pulse can be
used, and the phase difference is adjustable between
-360.0 and +360.0 to a resolution of 0.1 degrees. Skew
is better than 5ns.
When synchronizing two 2-channel generators it is possible
to have four closely synchronized and phase adjustable
waveforms. It is also
possible to synchronize more than two generators but
results are not guaranteed.
Included as Standard
These features are
included as standard on both the TG501xA and TG251xA,
unlike some competitor products for which they are an
expensive option.
