Make sure the grounding conductor of the spectrum analyzer is grounded before turning on the instrument. After which the AC power cord can be connected. Do not use a non-ground power cord. 4.2.2 Allowed Variation Range of Supply Power Parameters The spectrum analyzer is compatible with 100V~240V, 50Hz-60Hz AC power, Table 4-1 lists the power requirement to run the spectrum analyzer.
! ! WARNING Improper grounding may cause damage to the instrument, or result in personal injury. Make sure the grounding conductor of the spectrum analyzer is grounded before turning on the instrument. Always use a well-grounded power source. Do not use an external power cable, power cord or an auto transformer without grounded protection.
Make good use of anti-static technology to protect components from damage: 1) Quickly ground the internal and external conductor of the coaxial cable before it is connected with the spectrum analyzer. 2) Staff must wear anti-static gloves before touching the connector cord or doing any assemble work. 3) Assure all the instruments are grounded properly to avoid static storage. 4.3 First Time to Power on Connect the three-pin AC power cord into the instrument.

Figure 4-9 Set frequency span 4) Activate Marker —Press【Marker】button in the function area. Press the softkey to select [Marker 1 2 3 4 5 ], select Marker 1, the marker is located at horizontal center by default, that is the signal peak point or its neighbor. —Press Peak, and enter the next level menu, select [Max Search]. Frequency and amplitude values are read by the marker and shown on the top right of the display area.
The reference level is set at -20dBM, which is the signal peak value near the top of the grid. The balance between the signal peak value and noise is dynamic range.
5. Menu Interpretation This section provides you with the information on using the front panel of the spectrum analyzer. 5.1 【FREQ】Frequency The frequency range of a channel can be expressed by either of two groups of parameters: Start Frequency and Stop Frequency; or Center Frequency and Span.
5.1.2 [Start Freq] Sets the start frequency of the sweep. When pressed, the frequency mode is switched to Start Freq and Stop Freq in order to enter the desired parameter data. Key Points: The span and center frequency are changed automatically according to the start frequency. The change of the span would have influence on other system parameters. For more details, please refer to "Span". In Zero Span mode, the start frequency, stop frequency and center frequency are always equal.
The frequency step type could be "Manual" or "Auto". In Auto mode, the CF step is 1/10 of span if it is in Non-zero span mode or equals 25% of RBW while in Zero span mode; in Manual mode, you can set the step using the numeric, step keys or knob. Then activate 【Center Frequency】, press step, center frequency will change as setting step.
regarded as whole device reference. 5.2 【SPAN】 Set the spectrum analyzer to span mode. When press 【SPAN】, [Span],[Full Span],[Zero Span] and [Last Span] will be available to configure. You can modify span using the numeric keys, knob or direction keys. Use numeric key or [Zero Span] to clear span. 5.2.1 [Span] Sets the frequency range of the sweep. When pressed, the frequency mode is switched to Center Freq/Span. Key points: The start and stop frequencies are changed with the span automatically.
5.2.3 [Zero Span] Sets the span of the analyzer to 0 Hz. Both the start and stop frequencies will equal the center frequency and the horizontal axis will denote time. The analyzer here is measuring the time domain characteristics of amplitude, located at the corresponding frequency point. This will help to observe the signal (especially for modulated signal) at time domain. 5.2.4 [Last Span] Changes the span to the previous span setting. 5.3 【AMPTD】Amplitude Sets the amplitude parameters of the analyzer.
You can modify this parameter using the numeric keys, knob, or direction keys. Reference level located at the top of axis grid. Measurement near the reference level would gain better accuracy, but input signal amplitude should not exceed the reference level; if it exceeds, the signal will be compressed and distorted, result in wrong measurement. Analyzer’s input attenuation is related with reference level, it can self-adjust to avoid signal compression.
Attenuator adjustment is to make the maximum signal amplitude pass from mixer less than or equal to -10dBm. E.g. if the reference level is +12dBm, the attenuator value is 22dB, then the input level in mixer is -18dBm (12-22-8=-18), its mainly purpose is to avoid signal compression. Switch [Input Atten Auto Manual] to manual mode, adjust the attenuator manually. The highlight under auto or manual stands for auto coupling and manual coupling.
the value shown at top of the grid is the reference level and the grid size is equal to the scale value. The unit of Y-axis will be automatically switched into the default "dBm" when the scale type is changed from Lin to Log. In Lin scale type: the Y-axis denotes the linear coordinates, the value shown at the top of the grid is the reference level and the bottom of the grid shows 0 V. The grid size is 10% of the Reference level and the Scale/Div is invalid.
5) 6) 7) Choose decibel equals to 1mV as amplitude unit. [dBμV] Choose decibel equals to 1μW as amplitude unit. [W] Choose Watts as amplitude unit. [V] Choose Voltage as amplitude unit. 5.3.7 [Preamplifier On Off] Sets the status of preamplifier located at the front of the RF signal path. Turning on the preamplifier reduces the displayed average noise level in order to distinguish small signals from the noise when working with small signals. 5.
mode. Press [Resolution Bandwidth Auto Manual] and hold it until underline under Auto has been highlighted. Then the resolution bandwidth is under auto coupling mode. Key points: Reducing the value of RBW will increase the frequency resolution, but may also cause sweeps to take longer (Sweep Time is effected by a combination of RBW and VBW when it is in Auto mode). RBW decreases with the span (non-zero span) in Auto RBW mode. 5.5.
5.5.5 [EMI BW►] Pop out the menu for EMI measurement bandwidth. 1) [EMI bandwidth On Off] Turn on or off EMI measurement resolution bandwidth. 2) [1MHz] Set EMI measurement resolution to 1MHz. 3) [120kHz] Set EMI measurement resolution to 120kHz. 4) [9kHz] Set EMI measurement resolution to 9kHz. 5) [200Hz] Set EMI measurement resolution to 200Hz. 5.6 【Trace】 As the sweep signal is displayed as a trace on the screen, you can set parameters about the trace using this key.

But the trace stock will keep still without refreshing. 5.6.6 [View] Stops updating trace data and display current trace for observation.. 5.6.7 [Operations►] Enter trace math related sub menu. 1) [1 ↔ 2] Exchange the trace stock 1 data with trace stock 2 and place them in display mode.
5.7 【Detector】 While displaying a wider span, each pixel contains spectrum information associated with a larger subrange. That is, several samples may fall on one pixel. Which of the samples will be represented by the pixel depends on the selected detector type. Press this key to pop out the relevant menu includes [Auto],[Normal],[Pos Peak],[Neg Peak],[Sample]. Key points: Selects an appropriate type according to the application in order to ensure the accuracy of the measurement for your application.
Sample Sampling detector is conducive to measurement noise signal. Compared with the standard detection method, it can measure noise better. 5.7.1 [Auto] Set the detector to auto detection mode (default mode). In this mode, when the span is greater than 1MHz, the detection method is set as Normal. When the span is less than or equal to 1MHz, the detection method is set as Positive Peak. 5.7.
