Advantages of the E4980A

Accuracy:
Excellent performance for low and high impedance measure-
ments
The E4980A LCR meter provides impedance measurements with excellent per-
formance across all frequency ranges to meet the test requirements of the lat-
est devices. Compared to the 4284A LCR meter, the E4980A provides a wider
measurement range and increased data fluctuation to increase test quality and
reduce cost of test.
100 mohm measurement range for ultra-low impedance test
Option E4980A-001 can provide a 100 mohm measurement range for ultra-low
impedance measurements,

measurement range.
Wider measurement range, same accuracy
E4980A extends the test frequency range up to 2 MHz and enhances the accu-
racy capability to meet the stringent requirements of today's devices. Figures 1
and 2 shows the calculated measurement range graph for both the 4284A and
E4980A LCR meters based on their specifications. The measurement range of
the E4980A is wider than 4284A with the same accuracy across frequency
ranges making this instrument more suitable for both low and high impedance
measurements.
