USB Lock-In Amplifier 250
250 kHz 2-phase Lock-In 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.
The integrated PID control allows easy integartion into more complex setups.
It can be simultaneously operated with PCI-Lockin Amplifiers AMU2.4.
