Chapter 2 Front Panel Operation RIGOL Chapter 2 Front Panel Operation This chapter describes in detail the function keys at the front panel and the associated functions.
RIGOL Chapter 2 Front Panel Operation Basic Settings FREQ Set the frequency parameters of the analyzer. The analyzer sweeps within a specified frequency range and restarts sweeping every time the frequency parameters are modified. The frequency range of a channel can be expressed by either of two groups of parameters: Start Frequency and Stop Frequency ( f start / f stop ); or Center Frequency and Span ( f center / f span ).
Chapter 2 Front Panel Operation RIGOL Center Freq Set the center frequency of the current channel. Press this key to switch to center frequency/span input mode. The center frequency and span values are displayed at the lower left and right sides of the grid respectively. Key Points: The start and stop frequencies vary with the center frequency when the span is constant. Changing the center frequency horizontally shifts the current channel and the adjustment is limited by the specified frequency range.
RIGOL Chapter 2 Front Panel Operation span would affect other system parameters. For more details, please refer to “Span”. In Zero Span mode, the start frequency, stop frequency and center frequency are always the same. If one is changed, the others are updated to match. You can modify this parameter using the numeric keys, knob or direction keys. Refer to “Parameter Setting” for more details. Table 2-2 Start Frequency Parameter Explanation Default 0 GHz Range* 0 Hz to 7.
Chapter 2 Front Panel Operation RIGOL Table 2-3 Stop Frequency Parameter Explanation Default 7.5 GHz Range* 0 Hz to 7.5 GHz Unit GHz, MHz, kHz, Hz Knob Step Span > 0, step = Span/200 Span = 0, step = VBW/100 Min = 1 Hz Direction Key Step CF step Note: *The range is from 100 Hz to 7.5 GHz in non-zero span. Freq Offset You can set a frequency offset value to account for frequency conversions between the device under test and the input terminal of the spectrum analyzer.
RIGOL Chapter 2 Front Panel Operation CF Step Set the step of center frequency. Changing the center frequency in a fixed step continuously switches the channel to be measured. Key Points: The CF step can be set in “Manual” or “Auto” mode. In Auto mode, the CF step is 1/10 of the span in Non-zero span mode or equals the RBW while in Zero span mode; in Manual mode, you can set the step using the numeric keys.

Zoom Out Set the span to twice the current value. At this point, the signal on the screen is zoomed out to gain more information about the signal. Last Span Set the span to the previous span setting.
RIGOL Chapter 2 Front Panel Operation AMPT Set the amplitude parameters of the analyzer. Through modifying these parameters, signals under measurement can be displayed in a proper mode for easier obsercation and minimum error. Auto Scale This function enables the readout resolution of the Y-axis to be the maximum possible while at the same time ensures the completeness of the signal.
RIGOL Chapter 2 Front Panel Operation Figure 2-5 After Auto Scale Ref Level Set the maximum power or voltage can be currently displayed in the window. The value is displayed at the upper left corner of the screen grid. Key Points: The maximum reference level available is affected by the maximum mixing level, input attenuation and preamplifier.
RIGOL Chapter 2 Front Panel Operation Table 2-7 Reference Level Parameter Explanation Default 0 dBm Range -100 dBm to 20 dBm Unit dBm, -dBm, mV, uV Knob Step In Log scale mode, step = Scale/10 In Lin scale mode, step = 0.1 dBm Direction Key Step In Log scale mode, step = Scale In Lin scale mode, step = 1 dBm Input Atten Set the front attenuator of the RF input in order to ensure big signals (or small signals) to pass through the mixer with low distortion (or low noise).
Chapter 2 Front Panel Operation RIGOL Key Points: By changing the scale, the amplitude range available is adjusted. The range of the amplitude that can be displayed: Minimum: reference level – 10 × the current scale value Maximum: the reference level. You can modify this parameter using the numeric keys, knob or direction keys. For more details, please refer to “Parameter Setting”. Table 2-9 Scale Parameter Explanation Default 10 dB Range 0.
RIGOL Chapter 2 Front Panel Operation Units Set the unit of the Y-axis to dBm, dBmV, dBuV, Volts or Watts. Wherein, dBm, dBmV and dBuV are for Log scale; Volts and Watts are for Linear scale. The default is dBm. Key Points: The conversion relationships between units are as follows. Volts 2 1 dBm = 10log × R 0.001W (2-4) Volts dBµV = 20log 1µV (2-5) Volts dBmV = 20log 1mV (2-6) Volts 2 R (2-7) Watts = Wherein, R denotes the reference resistance.

RIGOL Chapter 2 Front Panel Operation Figure 2-7 After Auto Range Key Points: Unlike Auto Scale, this function can solve the problem of signal overrange due to parameter settings and adjust the maximum mixing level according to the signal under measurement. Unlike Auto, this function adjusts the signal within the current channel and does not modify the channel frequency setting. While, Auto will search for signal within the full frequency range and locate the signal at the center frequency.
RIGOL Chapter 2 Front Panel Operation Start Peak Search Peak > Ref Level? N Y Adjust Ref Level Large signal? N Y Decrease maximum mixing level Increase maximum mixing level Auto Scale Stop Figure 2-8 Process of Auto Range RF Preamp Turn on or off the preamplifier located at the front of the RF signal path. When the signal under measurement is small, turning on the preamplifier can reduce the displayed average noise level; therefor, you can distinguish small signals from the noise.
RIGOL Chapter 2 Front Panel Operation Correction Correct the amplitude in order to compensate for the gain or loss from external devices such as Antenna and Cable. When using this function, you can view the correction data table and save or load the current correction data. When amplitude correction is turned on, both the trace and related measurement results will be corrected; the corresponding icon the screen. is highlighted in the status bar at the left of 1.

Range: -120 dB to 100 dB Del Point Delete the specified point data in the correction factor: frequency and amplitude correction. 4.
RIGOL Chapter 2 Front Panel Operation MaxMixL Set the max input level of the mixer according to the magnitude of the signal. Key Points: For a larger input signal, select a smaller maximum mixing level to increase the input attenuation and reduce the distortion of the signal; for a smaller input signal, select a larger maximum mixing level to reduce the input attenuation and noise. Parameters in inequality (2-3) are always modified on the basis of the maximum mixing level.
Chapter 2 Front Panel Operation RIGOL Sweep and Function Settings BW/Det Set the RBW (Resolution Bandwidth), VBW (Video Bandwidth) and detector type parameters of the analyzer. RBW Set the desired resolution bandwidth in order to distinguish between signals which are close in frequency. Key Points: Reducing RBW will increase the frequency resolution, but will increase the sweep time (Sweep Time is affected by a combination of RBW and VBW when it is in Auto mode).
RIGOL Chapter 2 Front Panel Operation VBW Set the desired video bandwidth in order to filter out the noise outside the video band. Key Points: Reducing the VBW will smooth the spectrum line to differentiate small signals from noise, but will increase the sweep time (Sweep Time is affected by a combination of RBW and VBW when it is in Auto mode). VBW varies with RBW when it is set to Auto. While in Manual mode, VBW is not affected by RBW.
