2.1 Basic Settings 2.1.1 Frequency Set the frequency-related parameters and functions of the analyzer. The sweep will restart every time the frequency parameters are modified. The frequency range of a channel can be expressed by three parameters: Start Frequency, Center Frequency and Stop Frequency. If any of the parameters change, the others will be adjusted automatically in order to ensure the coupling relationship among them: f center � ( f s t a r t � f s t o p ) / 2 f span � f s t o p � f s t a r t 2.

The analyzer supports two kinds of RBW filters: “Gauss” (-3 dB bandwidth) and “EMI” (-6 dB bandwidth). When “EMI” is selected, resolution bandwidth can only be 200 Hz, 9 kHz, 120 kHz and 1 MHz “Quasi-Peak” detector is available only when “EMI” filter is turned on. 2.2.
1. Clear Write Erases any data previously stored in the selected trace, and display the data sampled in real-time of each point on the trace. 2. Max Hold Retain the maximum level for each point of the selected trace. Update the data if a new maximum level is detected in successive sweeps. Max Hold is very effective when measuring events that may take successive scans to measure accurately. Some common applications include FM Deviation, AM NRSC, and frequency hopping or drift. 3.
2. Input X, Y Input X, Y can be applied to trace A, B, C, or D. 3. Calculation Type The analyzer provides the calculation types as shown below: � Power Diff: X-Y+Offset→Z � Power Sum: X+Y+Offset→Z � Log Offset: X+ Offset→Z � Log Diff: X-Y-Ref→Z 4. Offset value Table 2-16 Offset value Parameter Explanation Default 0 dB Range -100 dB - 100 dB Unit dB Knob Step 1 dB Direction Key Step 1 dB 2.2.3 Detect The analyzer displays the sweep signal on the screen in the form of a trace.

Normal Normal detector (also called ROSENFELL Detector) displays the maximum value and the minimum value of the sample data segment in turn: Odd-numbered data points display the maximum value and even-numbered data points display the minimum value. In this way, the amplitude variation range of the signal is clearly shown. 5.
2.2.4.2 Sweep Rule The analyzer provides two sweep time rules to meet the different sweep time requirements: � Speed: Activates the default fast sweep time rule. � Accuracy: Activates the normal sweep time rule to ensure increased measurement accuracy. The Speed sweep time rule provides a fast measurement function that decreases the sweep time. While the Accuracy Sweep rule will increase the measurement accuracy. 2.2.4.3 Sweep Set the sweep mode in single or continuous, the default is continuous.
2.2.4.4 Sweep Mode Sweep mode includes auto mode, sweep mode and FFT mode. 1. Auto When the sweep mode is auto, the analyzer selects the sweep mode automatically between Sweep and FFT Mode in the shortest time. 2. Sweep True swept operation including point-by-point scanning. The Sweep mode is available when the RBW is in 30 Hz – 1 MHz. 3. FFT The FFT mode is only available when RBW is in 1 Hz - 10 kHz. When the tracking generator (TG) is on, the sweep mode is forced to Sweep. 2.2.4.

This calibration effectively eliminates the frequency response reflection tracking error, directivity error, and source match error from the test setup in a reflection test using that port. This function is only available when the measurement item is S11.
1. Extensions Port extensions mathematically compensate data for any known phase shift/delay and amplitude errors caused by fixtures or additional circuit elements that cannot be removed by calibration. Common examples include test fixturing that is required to use a particular circuit element or device. When port extensions are enabled, the “P” icon will be displayed near the calibration status in the upperleft portion of the screen. The default setting is Close (off). 2.

This value is also displayed in the status bar on the left side of the screen. � Return Loss � VSWR � Reflection Coefficient All three forms reflect the matching condition of the entire cable.
Selecting the appropriate frequency span (= start freq – stop freq) is not as obvious as it may seem. The resolution and maximum distance range are dependent upon the span, the number of frequency data points and the velocity factor of the cable. Therefore, the frequency span must be chosen carefully. There is a constraint that limits the frequency range: Maximum Distance (meters) = 7.

It is used to compensate the amplitude of peaks in different positions. The DTF calculates the peaks by the final receiving data which has been attenuated by the cable, thus the amplitude of peaks cannot show exactly where the mismatch position is.
No calibration data --- (displayed in gray) Calibrated Cor (displayed in blue) Need to re-calibrate C? (displayed in blue) Note: The calibration status is shown as “C?” which indicates that the scan frequency range is different from the time of calibration. Users need to re-calibrate in the current scan frequency range. 1. Correction Turn on or off the calibration. 2. Calibrate Calibrating with the specified mechanical calibration requires three loads: open, short, and match.
