16 CS700A Signal Generator Module Controls [View Menu]
Cleverscope can be fitted with the CS700A internal direct digitally synthesised signal generator module to
generate sine, square, and triangle waves, at a frequency between 0.002 Hz and 10 MHz. You can vary the
amplitude over the range 0  5V p-p and the offset over the range –4 + 4V.
The signal generator outputs samples at a 50 MHz rate and uses a 5th order modified Chebychev reconstruction
filter.

No sweeping occurs.
Frequency steps occur at fixed time intervals and are
asynchronous with the sampling system. Gain/Phase values
are not coherent with the signal generator frequency, and
records peak values across the entire spectrum range.
Frequency is only adjusted between sample frames. The
cycle is Set Frequency - Capture result... Set Frequency -
Capture Result. Since this is synchronous with the sampling
system no smearing of the spectra will occur. When
Gain/Phase is selected, the Spectrum Display automatically
interpolates from one frequency point to the next, and
gain/phase values are coherent with teh signal generator
frequency.
Synchronous capture with 50 points per frequency sweep
(decimated to freq step values).
Synchronous capture with 200 points per frequency sweep
(decimated to freq step values).
Automatically sweep the signal generator in the Acquisition
unit when doing a multi frame capture, in between
captures.
