250 kHz 2-phase LockIn Amplifier
The unique USBLockIn250 is a compact lock-in amplifier based on highest quality digital design.
Its parameters are comparable with the eLockIn203.
The control via USB-Interface allows to virtually connect an infinity number of USBLockIn250 to one PC.
Moreover, it can be simultaneously operated with PCI-Lockin Amplifiers AMU2.4.
