信号发生器ARB编辑软体使用手册

信号发生器简易使用手册一、概述信号发生器主要的功能是在手机测试时提供符合要求的信号，因此我们在使用前要先了解信号发生器的一些基本的性能指标（如所能产生的信号频率范围、幅值范围等），选择符合我们要求的仪器来进行测试。

信号的频率范围一般都会标在仪器的前面板上，使用前应多加留意。

下面我们就以Agilent E4438C ESG V ector Signal Generator为例来说明信号发生器的基本使用方法。

二、基本项设置和功能1、显示屏显示当前功能的信息。

信息包括状态指示，频率和幅值设置，错误消息。

软键的标注位于显示屏的右手边。

2、软键软键激活显示屏上对应的每个键的功能。

3、频率设置键按这个键可以设置有关频率的功能。

例如改变RF输出频率或使用菜单设置频率的属性如参考频率和频率偏差等。

4、幅值设置键按这个键可以设置有关幅值的功能。

例如改变RF输出幅值或使用菜单设置幅值的属性如功率搜索，用户平面和电平模式等。

5、旋纽旋转这个旋纽可以增加或减少数值或改变高亮数字或性能。

也可以使用它来列表中单步移动或在一行中选择项目。

6、菜单键这些键可以通过软键设置列表扫描和单步扫描，有用功能，LF输出和各种调制类型等。

7、保存键通过这个键可以将数据保存到仪器状态寄存器中。

仪器状态寄存器分为10个序列（0～9），每个序列包括100个寄存器（00～99）。

保存键允许保存和重现频率和幅值设置。

一当仪器状态被保存了，所有的频率，幅值和调制设置可以通过Recall键重现。

8、重现键重现先前保存在寄存器里的仪器状态。

9、外部输入连接端口1这个BNC（同轴电缆接插件）输入连接端口接受AM，FM和√M ±1 V p的信号。

对于所有的调制方式，±1 V p 形成指示的偏移或深度。

当为AM，FM或√M选择ac_coupled输入，峰值输入电压偏离1 V p 3％时，显示屏上的HI/LO指示高亮。

破坏电压是5V rms和10V p。

Product IntroductionThe frequency feedback method applied by GFG-3015 is a new technique that generates stable output frequency with extraordinary accuracy for Function Generator. The traditional function generators typically use integrating circuit and constant current circuit techniques that are easily affected by operation temperature or the quality of resistor or capacitor and other key components to occur poor frequency accuracy. The innovative design for GFG-3015 is to get rid of these problems. The frequency feedback system needs a compatible, powerful frequency counter. GW has designed his own full-function counter chip, GFC-9701, for this system with high frequency test range and full functions, including Period test, Duty test, Ratio test, Time interval, Pulse wide, direct display and direct connect with CPU system. GFG-3015 uses this Chip to read output frequency value at any time. Then CPU will modify the correct value of D/A converter immediately according to this value, so that the user can get a high accuracy frequency from GFG-3015 Function Generator. Besides, the GFG-3015 can also generate a high accuracy frequency to provide high frequency resolution.Graph1 indicates the fundamental construction of a frequency feedback system.D/A ConvertorVCOAMPO/PUser InterfaceCPUCounter (GFC-9701)Except the different design from the typical circuit, GFG-3015 system also has micro controller (CPU unit) equipping an additional RS-232 interface functions which will be used on any test system with other instrument or to be controlled by computer.GFG-3015p.53.

Photo 39395Brief descriptionADS is provided with two independently programmable synthesis channels.Thanks to its simple channel synchroniza-tion facility and precise phase setting, the ADS is ideal for generating complex sig-nals.ARB generators are essential tools for •digital modulation,•communications,•navigation,•automatic test equipment,•component testing,•audio and acoustics measurements,•material testing,•ultrasound measurements,•filter design,•video applications, control engineer-ing,•sensors and•automotive engineering.Complex modulation signalsThe ADS is a high-precision signal source for driving I/Q modulators to produce dig-ital modulation; it is particularly suitable for driving the I/Q modulator of Signal Generator SMIQ (page 133).Main features•Convenient editor functions for creating user-programmable waveforms, ARB sequences and ARB sweeps •12-bit amplitude resolution•64-Kpoints waveform memory per channel•Sine synthesis with high spectral purity (0.1 Hz to 5 MHz)•Generation of triangular waves with high linearity (0.1 Hz to 100 kHz)•User-programmable frequency sweep •ARB sequence mode for generating sig-nals with extremely long periods •Nonvolatile memory for storing 20 instrument setups as well as up to 99 ARB signals, ARB sequences and ARB sweeps•Memory card for waveform librariesSpectral purityThe low distortion (typ. −70 dB) and a fre-quency response of typ. 0.1 dB allow pre-cise audio measurements. The high spec-tral purity close to the carrier throughout the entire sinewave frequency range ena-bles testing of fast, high-resolution A/D converters.Trigger functionsA variety of trigger functions (SINGLE, GATE, RESET, HOLD and HOLD/RESET in ARB mode, SINGLE and STEP in sequence mode) is provided for control of signal generation. In the sine mode, the modula-tion modes FSK (frequency shift keying), PSK (phase shift keying) and PM (pulse modulation) can be selected in addition to the trigger functions HOLD and HOLD/RESET.

The complete waveform library stored by the user in theinternal memory can be accessed and isavailable for editing.Sequence modeIn this mode, ARB signals can be joinedup to a continuous programmedsequence. By assigning a repetition rateto any element in the sequence, it is pos-sible to create sequences that use a frac-tion of the memory capacity required forconventional ARB synthesis. Each ele-ment in the sequence can be assigned anindividual read clock frequency; in thisway, expanded ARB signals can beincluded in the sequence. The SEQ editorwhich is similar to the ARB editor is usedfor programming and modifying ARBsequences.Specifications in briefSpecifications apply to both synthesis channels of ADS Signal outputOutput voltage (AC), EMF0 to 20 V pp, Imax = ±100 mA,0 to10 V into 50 ΩDC offset setting range−5 to +5 V into 50 ΩSine0.1 Hz to 5 MHzTriangle0.1 Hz to 100 kHzPhase setting range CH1/CH2 −180° to +180°Trigger modesFrequency shift keying (FSK)phase-continuousPhase shift keying (PSK)setting range −180 ° to +180 °Pulse modulation (PM)Reset (RESET)triggered phase reset to 0°Hold triggered stopHold/Reset (HD/RS)triggered stop and resetSweep modeDigital, user-programmable frequency and phase sweeps,triggered internally, externally or manuallyUser-programmable waveformsLength2 to 65536 points, composite ARBsequencesAmplitude resolution12 bitsClock source (CLK)internal400Hz to 25 MHzwith ADS-B1200Hz to 33 MHzexternal DC to 33 MHzFilters(DC) 400 Hz to 33.33 MHz3rd-order Bessel filters, modified10 kHz, 100 kHz, 1 MHz, 2.5 MHz7th-order Chebychev filters, modified500 kHz, 5 MHzARB sequencesSequence length 2 to 8192 ARB curvesRepetition rate for single curves 1 to 65535, programmable Expansion factor(1 to 65535) x clock period, programma-ble for each ARB curveOperating modesContinuous mode CONTTrigger modes SINGLE, STEPTrigger mode trigger source internal, external,manual Internal triggering HCT/TTL-compatible, 50 ΩTrigger period 1 µs to 2000 sOn/off ratio adjustable, 1:6500 to 6500:1 Resolution, ON/OFF time min. 500 nsExternal triggeringInput impedance50 Ω/600 Ω, selectableTrigger threshold0.2 V/2.0 V, selectableTrigger edge up/down selectableTrigger state active LOW/HIGH selectable Frequency DC to 25 MHzMemory320 Kbyte, nonvolatileMemory card128 KbyteClock generator (option ADS-B1)Read frequency200 points/s to 33.33 Mpoints/s Resolution0.01%, min. 10 psReference frequencyInput/output frequency 5 or 10 MHz, selectableRemote control IEC bus (IEEE 488.2), in line with SCPI General dataPower supply100/230 V −10/+15%,120/220 V −15/+10%,47 to 420 Hz, 150 VADimensions (W x H x D)435 mm x192 mm x350 mmWeight14 kg for fully equipped unit Ordering informationDual Arbitrary Waveform Generator ADS1012.4002.02 OptionClock Generator ADS-B11013.5748.02 ExtrasMemory Card CMS-Z20841.1509.02 Software for ARB Signals AWD-K11026.4500.03 for I/Q Signals IQSIM-K1013.1642.02for COFDM Signals DAB-K11013.4649.02 Service Kit ADS-Z21013.1494.02。
