寫入在來自不同記錄道的數(shù)據(jù)之間執(zhí)行的計(jì)算結(jié)果。
將記錄道設(shè)置為計(jì)算模式時,從不同
記錄道、規(guī)格化顯示、每指定帶寬的功率顯示或曲線擬合顯示
根據(jù)設(shè)置的計(jì)算模式執(zhí)行。請注意,計(jì)算模式
只能為記錄道C、F和G設(shè)置。此外,可用的計(jì)算因記錄道而異

Writes the results of calculations performed between data from different traces. When a trace is set to CALCULATE mode, subtraction between data from different traces, normalized display, power display per specified bandwidth, or curve-fit display is performed according to the set CALCULATE mode. Note that CALCULATE mode can only be set for traces C, F, and G. Also, the available calculations vary from trace to trace. For more information, see chapter 6. Normalized Display Function > This function is one of the trace CALCULATE modes. It normalizes and displays the trace data. With normalized display, normalization is performed and the waveform is displayed with the waveform peak set to 1 if the sub-scale is linear, or set to 0 dB if the sub-scale is LOG. One trace can be normalized, either trace A, B, or C. If both traces selected for calculation are set to “BLANK”, then the sub-scale is displayed on the left side of the screen. Otherwise it is displayed on the right side. The calculation results are displayed in the sub-scale. The trace display at the side of the data area changes to “NORM @”. Curve Fit > Makes an approximation of the specified trace waveform. The result is written to TRACE G. Calculations are applied to data from the peak to the threshold value. The threshold value is set in the range of 0 to 99 dB (steps of 1). The trace display at the side of the data area changes to “CRV FIT @.” Peak Curve Fit > Makes an approximation of the specified trace waveform. The result is written to TRACE G. Calculations are applied to mode peaks at or above the threshold value. The threshold value is set in the range of 0 to 99 dB (steps of 1). The trace display at the side of the data area changes to “PKCVFIT @”.
