The UDT Tramp is a transimpedance amplifier (current-to-voltage) instrument which provides a low input impedance to accurately measure the short circuit current of phototransducers such as silicon and germanium photodetectors, vacuum photodiodes and photomultiplier tubes.
This model provides multiple gain selection and utilizes a common BNC connector for input and output connections for user convenience. A voltmeter, oscilloscope, chart recorder or any other voltage sensitive instrument may be used to monitor the amplifier output.
