The UDT TRAMP is a transimpedance amplifier (current-to-voltage) instrument that provides a low input impedance to accurately measure the short circuit current of photo transducers such as silicon and germanium photodetectors, vacuum photodiodes and photomultiplier tubes.

The TRAMP has been specifically designed as a low cost, lab quality instrument to interface silicon photodiodes to a variety of measurement equipment. 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.
