- Page 7 If a large parallel capacitance is connected to the input of this product, overshooting, ringing, or oscillation may occur. Make the input wiring as short as possible. We recommend 50-Ω coaxial cables with lengths of approximately 10 cm and 40 cm for the IV-202F4 and IV-204F3, respectively.

- Page 9 3.1 Overview The IV-202F4 and IV-204F3 are compact current-to-voltage conversion amplifiers with low noise characteristics. Wide bandwidths of up to 10 MHz and 1 MHz are realized for the IV-202F4 and IV-204F3, respectively. These products stably operate for up to an input parallel capacitance of approximately 20 pF (IV-202F4) or 50 pF (IV-204F3) without adjustment.
- Page 10 To compensate for input parallel capacitance, make adjustments by turning the adjuster clockwise. However, the upper cut-off frequency becomes lower as you turn the adjuster clockwise. * 3-1: approximately 20 pF or higher (IV-202F4). Approximately 50 pF or higher (IV-204F3). DA00062341-002...
