DDS Frequency Sweeper Accuracy ±1ppm Range 20Hz~60/120/160/320/520MHz
DDS Frequency Sweeper Accuracy ±1ppm Range 20Hz~60/120/160/320/520MHz Overview: Digital synthesis frequency sweeper adopts direct digital synthesis technology, microprocessor control; built-in detector, no need to detect the probe, can be completed within the range of 20Hz ~ 120MHz any frequency band amplitude frequency characteristics, phase frequency characteristics of the measurement.Sweep mode can be set arbitrarily, such as linear, logarithmic, point frequency, etc., can directly display the cursor position of the frequency value, amplitude value, phase value. 6.4-inch TFT color LCD screen, visual comfort, high clarity, Chinese/English menus, easy to operate, in the sweeping range of the cursor can be set up at the same time and display five, randomly configured RS232 interface, VGA (external monitor) interface, optional USB interface, print port. Features: ■ Frequency sweep signal source using direct digital synthesis technology, microprocessor control, embedded operating system■ Built-in detector, without detector probe can be completed within the range of 20Hz ~ 120M any frequency band amplitude frequency, phase frequency characteristics of measurement■ With external detector probe, the amplitude and frequency characteristics of any frequency band in the range of 1MHz~520MHz can be measured.■ Scanning mode can be set arbitrarily, such as linear, logarithmic.■ 6.4 “TFT color LCD screen, visual comfort, high clarity■ Chinese/English menu, easy to operate■ In the frequency sweep range can be simultaneously set and display five cursor measurement value■ The machine is equipped with RS232 interface, VGA (external display) interface■ Optional USB interface, print port■ Waveform storage, waveform analysis■ peak search: maximum value, minimum value search function■ Reference line search: reference peak, reference valley search function■ -3dB bandwidth measurement■ Q measurement function Main technical indicators: NameTechnical IndicatorFrequency Range20Hz~60MHz/120MHz/160MHz/320MHz/520MHz Frequency accuracy＜±1ppmMaximum frequency resolution1μHzSweep width20Hz～60MHz/120MHz/160MHz/320MHz/520MHz or spot frequency (zero sweep) Output level+13dBm～ -87dBm ( f≤60MHz） +10dBm～ -87dBm (f≤120MHz) 0dBm～ -87dBm (f≤520MHz)Output Impedance50Ω/75ΩOutput Level Resolution0.1dBmLevel flatness±0.5dB （after RF calibration）Phase Noise<-120dBc/Hz （20kHz off carrier frequency）Display ScaleLogarithmic scale Log: 0.1dB/gram to 10dB/gram Linear scale Line: 1mV to 5VAmplitude Resolution0.1dBSweep TimeAuto, Manual （50ms～10s）Free Vernier5，Frequency arbitrary settingDisplay range80dBDynamic range70dBInput Impedance50Ω/75Ω/1MΩ selectable (internal detector)Detector probeFrequency range 1MHz～520MHz Dynamic range 60dB Characterized impedance 50ΩPhase Measurement FunctionPhase Measurement Range：-180°～+180° Phase error≤±1°InterfacesStandard RS232, VGA interface, optional USB, print portDimensions344mm×200mm×385mm （W×H×D）Weight6kg
