All of the functions of a high-level RF signal
generator at a fraction of the cost
The DSG800 provides conventional sweep and analog
modulation functions as well as a pulse train generation
function normally reserved for high-level signal sources.
● Flexible frequency and amplitude sweep functions
● Complete AM/FM/ØM analog modulation functions
● Standard LF output function
● Powerful pulse modulation function
● System atness calibration function
● Simple and easy to operate
Measured level repeatability @ 1 GHz, 0 dBm
When the RF signal generator is used as a reference
source, we often pay more attention to the amplitude
stability and frequency stability of the output signal.
Amplitude stability is mainly determined by the internal
ALC (Automatic Level Control) circuit of the RF signal
generator. The ALC circuit is used to compensate for the
amplitude deviation that may result from temperature
changes. The DSG800 features a specially designed
digital ALC scheme that ensures high precision and
stability of the output signal. Frequency stability is mainly
determined by the internal reference clock stability. The
frequency stability of the DSG800 can reach 5 ppb by
installing high stable reference clock option OCXO-B08.
The high stability reference clock can also output a signal
used as the frequency benchmark of the entire test
system so as to enhance the overall level of frequency
stability.
Flexible frequency and amplitude sweep functions
The DSG800 supports frequency and amplitude
sweeping with step, list, logarithmic, and linear functions
as well as continuous and single sweep modes. The
RF signal generator can be congured to perform step
sweeps for amplitude and frequency characterization of
RF components. It can also sweep according to a user
denable sweep list.
