Small signal measurement instruments
Wideband current-to-voltage converter with compact size.
I/V converter for high frequency signals up to 10MHz.
Realize both low noise and wide bandwidth
Input current against frequency
Amplifies small current such as sub nano-Amp.
Amplifies small and high frequency signals of 1MHz with 4M (V/A) gain.
Gain against cut-off frequency
High gain amplifiers with high frequency response (1 MHz to 10 MHz).
pA/√Hz (10-12) order of current noise density
Amplifies high frequency small current signal with low noise.
Equivalent input noise current density against cut-off frequency
IV-200 series :
Low noise amplifiers with high frequency response (1 MHz to 10 MHz).
Output waveforms (square wave)
recommended for larger currents.
The IV-204F3 (up to 1MHz) is recommended for 1nA to 100nA. The IV-202F4 (up to 10MHz) is
* If a large input parallel capacitance is connected to this product, overshooting, ringing, or oscillation may occur. In this case, the FREQ ADJ adjuster may be able to improve measurement stability.
