摘要： A power spectrum waveform is obtained by logarithmically amplifying a signal received by a frequency-sweep operation, detecting the amplified output of each frequency sweep, converting the detected output into a digital signal value in decibels, and converting this digital signal value into an antilogarithmic power value in watts for each display point within the width of the frequency sweep. Upon completion of the frequency sweep operation, the power values which have been converted into antilogarithmic values for each frequency sweep are averaged for each display point, the average power values are converted into logarithmic values, and the logarithmic values are displayed as a spectrum display.

摘要： An information recording medium capable of avoiding insertion of a sheet material into a drive unit. The information recording medium is comprised of a tape cartridge that rotatably accommodates a tape reel wound with a tape-shaped recording medium (magnetic tape), a storage case that accommodates the tape cartridge, and a sheet material that is accommodated in the storage case together with the tape cartridge. The sheet material is formed to have a size in an unfolded state small enough to be accommodated in the storage case, and is accommodated in the storage case in a state where the sheet material is folded along a folding line.

摘要： An input signal from an antenna is level-adjusted by a first level adjuster and then frequency-converted by a frequency converter. The frequency-converted signal is further level-adjusted by a second level adjuster and then detected by a detector, and the detected output is displayed on a first display. A control signal for controlling the frequency of a local oscillation signal of a local oscillator, which is applied to the frequency converter, is adjusted to select the input signal to be measured. The control signal is applied to a compensating signal generator to derive therefrom a compensating signal for compensating for the frequency characteristic of the antenna. The compensating signal, a first set signal representing the set value of the first level adjuster, and a second set signal representing the set value of the second level adjuster are added together. The added output is applied to a second display to indicate the antenna input value provided at the time when the first display indicates a reference level of the first display, thus measuring the electric field intensity of the input electric wave.

摘要翻译： 来自天线的输入信号由第一电平调节器进行电平调整，然后由变频器进行频率转换。 频率转换信号由第二电平调节器进一步电平调整，然后由检测器检测，并且检测到的输出被显示在第一显示器上。 调整用于控制施加到变频器的本地振荡器的本地振荡信号的频率的控制信号，以选择要测量的输入信号。 控制信号被施加到补偿信号发生器，从而得到用于补偿天线的频率特性的补偿信号。 补偿信号，表示第一电平调节器的设定值的第一设定信号和表示第二电平调节器的设定值的第二设定信号相加在一起。 将附加的输出应用于第二显示器，以指示在第一显示器指示第一显示器的基准电平时提供的天线输入值，从而测量输入电波的电场强度。
