Page 73 4. Operating Instruction 4.1 Function operation guide The following methods are commonly used to set the frequency measurement range of Series Signal Analyzer through 【Frequency】 key, 【Span/X Axis】 key and corresponding soft menus; for programming methods under program control mode, please refer to program control manual: Method 1.
Page 74: Settings Of Bandwidth, Filter And Sweep„„„„„„„„„„„„„„„„„„„„„„„„„60
Method 2. Adjust the measurement span through the Up/Down key and knob on the front panel. The span step corresponding to the Up/Down key on the front panel of 4051 Series Signal/Spectrum Analyzer is based on way of 1-2-5-10, while the step size corresponding to the knob is 1/10 of maximum order of current span.
Page 75 The smaller the resolution bandwidth is, the deeper the dip goes. Therefore, distinction between two adjacent signals will beclearer. The desired resolution bandwidth can be realized with IF filter by 4051 Series Signal/Spectrum Analyzer under swept spectrum measurement mode or with FFT filter under FFT spectrum measurement mode. FFT filter can be understood as the window function operation before executing FFT spectrum operation.
Page 76 4. Operating Instruction 4.1 Function operation guide The parameters corresponding to the 【Sweep】 on the front panel include [Sweep Time], [Sweep Single Cont], [Sweep Setup▶] and [Sweep Points]. [Sweep Time] is used to set and indicate the time that is used by the Series Signal Analyzer to execute one measurement.
Page 77 [Bandwidth/RBW] and current span. There are over 160 scales of settings for the resolution bandwidth of 4051 Series Signal/Spectrum Analyzer, with 25 per 10 octave within 1 Hz - 1 MHz, changing by 10% step between 1Hz and 3 MHz and taking 4 MHz, 5 MHz, 6 MHz, 8 MHz, 10 MHz and 20 MHz above 3 MHz.
Page 78  Configure sweep type rules manually For the 4051 Series Signal/Spectrum Analyzer, the sweep type includes sweep frequency and FFT, while the sweep type rules include ―Best Dynamic Range‖ and ―Best Speed‖. ―Best Dynamic Range‖ rules: when RBW is or larger than 300Hz, the sweep type is Swept; when RBW is less than 300Hz, the sweep type is FFT.
Page 79 Analyzer adopts filter approximate to the rectangular shape to complete filtering of resolution bandwidth. The response time of flat top filter of 4051 Series Signal/Spectrum Analyzer is about 3 times of that of the Gaussian filter, as the sweep speed of the flat top filter is smaller than that of the Gaussian filter. The flat top...
Page 80 The filter bandwidth can be selected manually by activating the [Filter BW] through 【BW】 key on the front panel. The 4051 Series Signal/Spectrum Analyzer has four ways to describe the Gaussian filter bandwidth: 3 dB and 6 dB bandwidth of filter, pulse bandwidth and noise bandwidth. Wherein: the noise bandwidth refers to the bandwidth when the rectangular filter is used to pass through the noise signal power with same peak gains.
Page 81 Generally, that measured by the 4051 Series Signal/Spectrum Analyzer is the level value of input signal, while that displayed by the measured result is the effective value of the unadjusted sine signal level calibrated and corrected.

Under the spectrum analysis mode, the 4051 Series Signal/Spectrum Analyzer has many trigger modes, including free trigger, video trigger, power trigger, external trigger 1, external trigger 2, burst signal trigger and timer trigger.
Page 85 Except the free trigger, other trigger modes have the settings of trigger delay. The 4051 Series Signal/Spectrum Analyzer can set the trigger delay for these trigger modes respectively and the [Trig Delay ON OFF] menu is located in the submenu of each trigger mode.
Page 86 4. Operating Instruction 4.1 Function operation guide Fig. 4.2 Setting Interface of Video Trigger Prompt Applicable conditions of video trigger Usually, the video trigger is applied to the time domain power measurement under zero span, while, under non-zero span (span > 0 Hz), the correct spectrum measurement may not be executed if the video trigger is set, then the burst signal trigger mode will be used instead of video trigger.
Page 87 IF power trigger, then the IF bandwidth is also known as trigger bandwidth. When the burst signal of the 4051 Series Signal/Spectrum Analyzer is triggering, the trigger bandwidth is about 200 MHz. When the non-zero bandwidth is being measured, the second IF signal approximately represents the signal of start frequency relating to the measurement of analyzer;...

As the internal time base of the Series Signal Analyzer is different from that of the signal being measured, the input of timer will drift during the sync holdoff of timer. The timer offset determines the actual time of occurrence of the trigger event, when the timer trigger has occurred, the Series Signal Analyzer will not carry out the measurement until the trigger delay time if the trigger delay is on-state.

Operating Instruction 4.1 Function operation guide The parameters of corresponding menus will be modified accordingly after the auto parameter settings in the 【Couple】menu are modified. 4.1.2.8 Input and output settings The input and output settings are effective under all measurement modes and measurement functions of Series Signal Analyzer.
Page 92 However, the AC coupling will limit the frequency measurement range of the Series Signal Analyzer, mainly the measurement of lower frequency signal, e.g., the input signal less than 10 MHz. For the signal less than 10 MHz, the measurement performance of the 4051 Series Signal/Spectrum Analyzer is guaranteed under DC coupling.
Page 93 4. Operating Instruction 4.1 Function operation guide The settings and use methods of the reconstructed any IF output will be described below. The function of the reconstructed any IF output is only applicable to the transient analysis in the I/Q analysis mode and signal analysis mode.
Page 94 The IF output frequency can also be adjusted with the menu of [Reconstructed IF ▶] and [Digital Gains]. The gain of the 4051 Series Signal/Spectrum Analyzer is 0 dB by default, then the IF output power is 8 dB - 12 dB less than the RF output power, e.g., if the RF intput power is -10 dBm, the IF output power is -18 dBm to -22...

Page 728: Amplitude Accuracy
Appendix Appendix A Terminology sweep time. Most signal/spectrum analyzers use LC filter, crystal filter, active power filter and digital filter to enable different resolution bandwidths. Amplitude accuracy: A parameter, associated with the result of a measurement, that characterizes the dispersion of the values that could reasonably be attributed to the measurement.
Page 729: Detection Mode
Appendix Appendix A Terminology Detection mode It is a way of processing before analog information is digitalized and saved in the memory and serves mainly as a method of display detection for signal energy. It includes normal, Peak, negative peak, sample, and average modes.
Page 730: Signal/Spectrum Analyzer
Appendix Appendix A Terminology Signal/spectrum analyzer The instrument used to effectively display each single spectrum component (sine wave) composing the time- domain signal. Whether to retain phase information depends on the type of analyzer and relevant design principles. flatness It corresponds to the variation in display amplitude of the measurement frequency range of the signal/spectrum analyzer and indicates the corresponding relation between the signal amplitude variation and the frequency.
Page 731: Input Amplitude Range
Appendix Appendix A Terminology of the detector output and the displayed trace is smoothed. The degree of such average or smoothing is associated with the video bandwidth and the resolution bandwidth. The video average is done point by point during several sweep operations. At each point, new measured data and previous data are averaged together and average values of several measurements will be centrally displayed.
Page 732: Preselector
Appendix Appendix A Terminology Preselector The low-pass filter with tunable center frequency before the input mixer of the signal/spectrum analyzer. It is used to eliminate multiple and image responses of the superheterodyne signal/spectrum analyzer and improve its dynamic range. The preselector generally uses bands over 4 GHz. Sensitivity The capability of the signal/spectrum analyzer to measure signals with lowest level.
Page 733: Negative Peak Value Detection
Appendix Appendix A Terminology point. The minimum value and the maximum value among such data points are extracted and connected with a vertical line during trace display. Such mode helps direct analysis of noise signal fluctuation range and increase in the sweep time will widen the displayed noise bandwidth. Negative peak value detection It is a display detection method for signal energy.
