Complete AM/FM/ØM analog modulation functions
The DSG800 comes fully equipped, even in its standard
conguration. The AM/FM/ØM analog modulations
are included and the instrument also supports internal
and external modulation sources. The optional input
impedance of the external modulation can match the
impedance change of an external load. In addition,
the external modulation supports AC and DC coupling
modes to adapt to different types of modulation signals.
The DSG800 can also modulate two different modulation
sources (internal or external source) at the same time.
Thus, it can produce a hybrid modulated signal similar to
FM + AM.
Standard LF output function
The DSG800 can output the LF signal (such as DC,
sine and square waveforms) via the LF connector for a
variety of simulation testing environments. The LF signal
and the internal modulating signal are independent of
each other. Both the RF and LF signal sources can be
enabled at the same time.
Powerful pulse modulation function
The DSG800 not only supports external pulse
modulation, but also features an internal pulse generator
which can produce baseband signals with adjustable
cycle and pulse widths. In addition, it can also load a
user-dened pulse list to generate a pulse train. The
pulse train can be used as the modulating signal of pulse
modulation and can also be output as an independent
pulse generator.
The DSG800 can produce high quality pulse modulated
signals. The rise/fall time is less than 10 ns, and the on-
off ratio is greater than 70 dB.
System atness calibration function
The atness calibration function can compensate for
external amplitude loss caused by cables, RF switches,
adapters or other devices.
The DSG800 provides a user-dened atness correction
list function. You can download and activate the function
by generating a CSV format le using a spreadsheet
like Microsoft Excel© on a computer. With the help of a
computer, users can exibly edit calibration points and
easily adjust the amplitude calibration over the desired
frequency range.
