eLockIn 205

- digital quad-channel high-frequency Lock-In Amplifier -

e LockIn Amplifier 205
Input sampling rate of more than 500 MHz
(fully digital design, 10 MHz bandwidth)
real quad-channel amplification in the full frequency range
4 channel output data with 1 μs group delay
dual harmonic mode in the full frequency range
on-screen 4-channel spectra acquisition
web-interface for external communication
DLL available
Being the top model eLockIn series, the eLockIn205/2 offers a very fast TCP/IP connection, ultra-fast DAC outputs of the measured signals and all signals supplied at BNC connectors.

The eLockIn205/2 can be used as spectrum analyser, oscilloscope, sine generator or as measurement control system. It provides 8 ADC channels as external inputs and controls 8 DAC channels with 1 μs group delay as external signal outputs.
It can store 128 MByte data, provides modern network connection and USB connection.
Moreover, it acts as web server and all data are available over the internet.
