摘 要：

PROBLEM TO BE SOLVED: To provide a respective values of a positive peak and a negative peak, and to provide

concurrently an average value thereof, without imposing a processing load to an analyzer, to display them.;SOLUTION: A signal output from a VBW filter 16 is detected by a detection part 18. The detection part 18 has a positive peak detecting means 18a for detecting the maximum value of the signal, and a negative peak detecting means 18b for detecting the minimum value of the signal, and holds a positive peak value and a negative peak value respectively. A switch 28 is switched by each clock of an A/D-converting part 19, and outputs the respective peak values to a switch waveform memory 20. A signal-processing part 21 conducts reading in a sampling period with an N-multiplied (N=2 or more) value of that in the A/D

converting part 19 with respect to display in a display part 19, and calculates the average value by an averaging

processing part 22 to update it on a real-time basis to be displayed on the display
