产品适用范围：科研和研发领域

仪器简介：
 Bandwidth and Frequency Response 
Naturally, high gain amplifiers cannot achieve the speed of models with low gain. Due to the special FEMTO amplifier design measurements of extremely low currents can be 
performed with the LCA-2-10T in real-time. Signal changes can be monitored with a rise time down to 200 ms. For applications where response time is of lower importance the 
built-in ** filters can be used to further improve the sensitivity and noise performance of the measurement setup. Three filter settings allow adaptation to many different 
**s and measurement tasks. 
Applications 
Sensitive Current and Charge Measurements 
Spectroscopy 
Scanning Microscopy of Very High Impedance Samples (STM, conductive AFM) 
Photodiode Amplifier 
Characterization of Electronic Components 
Preamplifier for Oscilloscopes, A/D Converters, Digital Voltmeters etc.
技术参数：
Extremely Low Input Noise Current of 0.18 fA/√Hz 
Variable Gain 1012 V/A and 1013 V/A 
Variable Low Pass Filter 2 Hz, 0.3 Hz and 0.1 Hz 
Optimized for DC Measurements
主要特点：
High Gain for Low Noise Performance 
In order to attain an extremely low noise performance very high gains were chosen for the LCA-2-10T amplifier. A real transimpedance gain of 1012 V/A enables the extraordinary 
low input noise current of 0.18 fA/√Hz. An additional amplifier stage with a variable voltage gain of x1 and x10 was added to offer greater flexibility for varying applications 
and ** amplitudes. Like this an unparalleled sensitivity is achieved allowing real-time current measurements from 1 fA up to 10 pA without the need for further ** 
averaging.
