| 在被測定物上施加正弦波信號，求出其頻率響應(yīng)特性的裝置，稱作FRA（Frequency Response Analyzer，頻率特性分析儀）。因為測量的動態(tài)量程非常寬闊，所以不但能夠進(jìn)行高精確度的測量，而且具有可以測量超低頻率等特長。 | | 5010A | FRA5020A | | Oscillator | | Frequency resolution | 4 digits | 4 digits | | Output waveform | | | | Output voltage | 10mV to 5Vrms | 10mV to 5Vrms | | Isolation voltage | - | - | | Analyzer | | No. of input channel | 2 | 2 | | Input voltage range selection | Auto ranging | Auto ranging | | Isolation voltage | ± 14.2V (floating) | ± 14.2V (floating) | | Analysis mode | CH1/OSC, CH1/CH2 | CH1/OSC, CH1/CH2 | | DC bias elimination | Automatically eliminated over the entire frequency range | | Integration cycles | 1 to 100 | 1 to 100 | | Judgement function | UNDER, GO and OVER | - | | Display device | Indicator tube | CRT (green) | | Display mode | log R • θ, numerical | Nyquist, Bode and Nichols diagram, numerical | | Miscellaneous | | External display device | - | video printer, plotter (HPGL) | | Memory | 10 spots | 10 panel settings and 2 measurement data | | Interface | GPIB | GPIB | | Power requirements | AC100, 120, 220 or 240V switchable | AC100, 120, 220 or 240V switchable | | Dimensions (mm) | 432(W) X 132.5(H) X 400(D) | | Weight | Approx. 9.5kg | Approx. 12.5kg | | |
