Flat frequency response without peaking was an important design requirement. The maintained bandwidth with gain permits accurate high-speed acquisition whilst preserving the signal shape independent of gain setting. The gain can be selected from 10-60dB in steps of 10dB, corresponding to voltage gain factors from 3.16-1,000. Input coupling can be switched between AC and DC and the bandwidth can be set to 10/20MHz for reducing broadband noise.
All parameters can be selected manually or via the LUCI-10 digital interface. This combination of quality features makes the DHPVA series a universal laboratory amplifier facilitating signal processing.
