The
TP801-PCI and the Handyscope HS3 are equipped with an arbitrary
waveform generator. The HS4 does not have this capability.
The
function generator offers five default signal shapes: sine wave,
triangle, square, DC and white noise. The selected signal shape is
immediately shown in the display of the generator.
The
amplitude of the signal can be freely set between 0 V and 12 V peak.
A DC offset between 0 and 12 V (TP801: 10 V) can be applied to the
signal. Also the symmetry of the signal can be changed, from 1% to
99%. The frequency of the signal can be set from almost 0 to 2 MHz.
The
function generator also offers a sweep function. The sweep function
operates together with the spectrum analyzer. It can be set manually
but it can also copy the sweep limits from the lower frequency and
higher frequency from the spectrum analyzer. Together with the
"measure maximum values" mode from the spectrum analyzer
this gives a fast and easy way to create frequency response graphs.
It
is also posible to generate a signal that was previously measured
using the oscilloscope. With the File button a signal file can be
loaded into the function generator memory. The generator will then
generate this signal, whilst the amplitude, and frequency, can still
be adjusted.
Eight
user definable presets are available, in which often used signals
can be stored. With a single click on a button the required signal is generated
