Physical Lab proudly introduces the Ultra Precision Measurement Amplifier. The amplifier is suited for all kind of ultra-precise measurements. The response of the amplifier is flat (± 0,1dB) from DC to 100kHz! This makes the amplifier also interesting for ultra-sonic sound measurements. The amplifier also feature additional XLR current sense outputs for impedance measurements of the DUT. Three selectable gain modes (0dB, 10dB and 20dB) ensure the best range for your requirements.
