应用指南/技术说明书RIGOL5 应用指南/技术说明书 简介无论是传统的模拟示波器还是现代的数字示波器，测量信号频率的功能从产品诞生之日起就具备了。
早期的模拟示波器，测频过程需要工程师手动调节水平时基、触发等功能使得屏幕上呈现出1到2个周期的稳定波形后，通过观察该信号一个周期内占据的水平格数，再参考水平时基估算出信号周期，最终得到频率。
近些年随着数字示波器在测量技术在精度、速度以及使用便捷性等诸多方面突飞猛进的发展，示波器能够自动且快速的完成信号频率测量，并呈现到屏幕上，方便工程师进行读取。
RIGOL TECHNOLOGIES, INC.DSA1000 series is a 3GHz general purpose spectrum analyzer. With its stable performance as well as overall and easy-to-use test functions, it can fulfill most of the spectrum-related test and application requirements, such as maintenance, production and education. In addition, it is ahighly cost effective instrument that is worth having.All Digital IF TechnologyFrequency Range: 9 kHz to 3 GHzDisplayed Average Noise Level Up to -148 dBm (DSA1030A) Phase Noise up to -88 dBc/Hz @10 kHz offset (DSA1030A) Total Amplitude Uncertainty <1.0 dB(DSA1030A)Minimum Resolution Bandwidth (RBW) : 10 Hz (DSA1030A) Quasi-Peak Detector & EMI Filter (Standard)3 GHz Tracking Generator (for DSA1030-TG and DSA1030A-TG) Advanced measurement functions (option for DSA1030 and DSA1030-TG, standard for DSA1030A and DSA1030A-TG) 8.5 inch widescreen display (800X480)Complete Connectivity: LAN, USB Host&Device, VGA, USB-GPIB (optional)Compact size, light weightProduct Dimensions: Width X Height X Depth = 399 mm × 223 mm × 159 mm Weight: 6.2 kg (Without Battery and Package)Benefits of Rigol's all digital IF designUnique widescreen display, friendly interface and easy-to-use operationsPower ONLastFactory Preset User PresetPresetStatus saving and loading such asSetup State TraceCorrections Measure Marker Table Peak Table Limit1RIGOLDSA1000 Series provides a series of automatic setting functions such as Auto Tune, Auto Range, Auto Scale and Auto Couple that enable the analyzer to acquire signals and match parameters automatically, instead of the manual process used by a traditional analyzer. In addition, the User and Factory settings under the Preset function enable users to quickly and easily recall previous measurement settings.With the DSA1000 Series get a high quality spectrum analyzer without the price tag. This lowers the investment whether you are in stages related to research and development or manufacturing and maintenance. Don't let instrumentation costs dictate resource allocation. With our available calibration and maintenance training as well as firmware updates never regret a purchase because of total cost of ownership.1. The ability to measure smaller signals: on the basis of this technology, the IF filter enables smaller bandwidth settings, which greatly reduce the displayed average noise level.2. The ability to distinguish between small signals by frequency: using the IF filter with the smallest bandwidth setting it is possible to make out signals with a frequency difference of only 10 Hz.3. High precision amplitude readings: this technology almost eliminates the errors generated by filter switching, reference level uncertainty, scale distortion, as well as errors produced in the process of switching between logarithmic and linear display of amplitude when using a traditional analog IF design.4. Higher reliability: compared with traditional analog designs, the digital IF greatly reduces the complexity of the hardware, the system instability caused by channel aging, and the temperature sensitivity that can contribute to parts failure.5. High measurement speed: the use of digital IF technology improves the bandwidth precision and selectivity of the filter, minimizing the scanningtime and improving the speed of the measurement.Breadth of measurement functions andautomatic settings provide ultimate flexibilityIncomparable ValueAdvanced Performance and stabilityStability and precision is the primary design goal of the DSA1000 Series. We started with an all digital IF core. With the minimum 10Hz resolution bandwidth, -88 dBc/Hz phase noise (typical) at 10 kHz offset, up to -148 dBm displayed average noise level (10 Hz RBW, standard preamplifier on) and less than 1.0 dB total amplitude error, the DSA1000 Series makes high precision measurements easier than ever whether the application calls for low noise or narrow resolution.RIGOL 2Features and BenefitsDistinguish the two nearby signals clearly with the 10Hz RBWReadout the signal's Phase Noise directly by using the standard Noise Marker functionCompare the spectrums with different color trace The advanced Occupied Bandwidth measurement function The advanced Harmonic distortion measurement functionReadout the Spectrum Peak values with the Peak table functionThe advanced Channel Power measurementfunctionQuasi-Peak Detector & EMI Filter (Standard)RIGOL Spectrum Analyzer Option and AccessoryVSWR Bridge( VB1020/VB1040)Rack Mount Kit ( RM-DSA1000 )USB to GPIB Converter( USB-GPIB )RF Demo Kit ( TX1000 )RF CATV KitRF Demo Kit ( RX1000 )Soft Carrying Bag ( BAG-DSA1000 )DSA Utility Kit RF Cable Kit( CB-NM-NM-75-L-12G )( CB-NM-SMAM-75-L-12G )RF Adaptor Kit High Power Attenuator( ATT03301H )RF Attenuator KitDSA PC Software ( Ultra Spectrum )Advanced Measurement Kit（AMK-DSA1000）3RIGOLDesk Mount Instrument Arm(ARM)SpecificationsSet “Auto SWT” to “Accy”Resolution Bandwidth (-3dB)10 Hz to 1 MHz, in 1-3-10 sequence 100 Hz to 1 MHz, in 1-3-10 sequence Bandwidth (-6dB)200Hz, 9kHz, 120kHz, 1 MHz 200Hz, 9kHz, 120kHz, 1 MHzRBW Uncertainty<5%, nominal Resolution Filter Shape Factor (60 dB : 3 dB)<5, nominalVideo Bandwidth (-3dB) 1 Hz to 3 MHz, in 1-3-10 sequencefc ≥ 50MHz, preamplifier offSpecifications are valid under the following conditions: the instrument is within the calibration period, is stored for at least two hours at 5℃ to 40℃ temperature, and is warmed up for 30 minutes.
