以下是 1960 年以來 LCR 產品的總表,並建議了合適的替代品。
4200 Series => 4300 Series
Specifications | Old Model | Replacement Model |
---|---|---|
Model | 4200 Series | 4300 Series |
Available | Made between 1983 and 2013 | First made in 2009 and still in production |
Basic Accuracy | All 4200 Series models: 0.1%, except for the 4225: 0.25% | 0.1% |
Frequency Range | 42(10, 25): 100Hz, 1kHz, 10kHz
4250: 100Hz, 1kHz, 10kHz, 100kHz
4230: 100Hz - 200kHz
4265: 50Hz - 100kHz
4270: 50Hz - 1MHz | 20Hz to 100kHz |
The recommended replacement for models in the 4200 Series is the 4300 Series Model. The 4300 Series Models offers significant improvements over the older models, including:
-
Lower minimum frequency (20Hz)
-
Many more measurement frequencies (557 steps)
-
Extra measurement parameters (Z, Y, θ, B, G, X)
-
Wider AC Drive range (10mV to 1Vrms)
-
Many more AC Drive levels (200 steps)
-
Faster measurement speed
-
DC resistance as a standard feature
-
Larger and easier-to-read display
-
Autoranging AC input voltage
For applications requiring a measurement frequency greater than 100kHz, three additional 4300 models are available:
-
4320: 20Hz to 200kHz
-
4350: 50Hz to 500kHz
-
43100: 20Hz to 1MHz
