CS1351 Synthesizer Sweep Generator uses the new
technology of TDSP,FPGA,DDS,GPU,PLL,and the frequency range is
from 1-1000MHz with the frequency precision of 100Hz.At speed of
20ms,it still can make 200 points continuously,while at the max
sweeping speed of 10s, it can send out 100000 points.It has
dominant superiority for analyzing instrument or system F-V.The
Frequency Mark system of this instrument consist of five ones, and
it can be settled arbitrarily in the sweeping ranges,the precision
of marks is better than 100Hz.Due to using DDS+PPL,the precision
and stabilization of CWare much more than others,so it is a
high-precision instrument,as well as a high-precision sign
generator.It can be used in high-frequency and super
high-frequency four-port nets as a general instrument. While it is
usually used in radio,commumication and radar systems.Applying to
teaching and research,it can use for measuring the nets and
devices.
