In the cooled mode, the detectors must be working with Temperature controller( ZTC )
Tranc-impedance Amplifier ZAMP is recommended.
?DInAs3800 and DInAs3800-TE detectors are current output mode, before connecting to the signal processors such as oscilloscope or lock-in amplifier, the IV Trans-Impedance Amplifier ZPA-101 is recommended as a preamp and which can convert the current to voltage output.
?DInAs3800-TE must be working with Temperature controller (ZTC) for cooling control.
