eLockIn204/2

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

The eLockIn204/2 is quite similar to the eLockIn204 - the only difference is, that the model eLockIn204/2 has 2 lockin inputs! Therefore the lockin amplifier has several parameters and features which are only found in these Anfatec instruments. The most unique are:

Input sampling rate of 40 MHz (fully digital design, 1 MHz bandwidth)
Real quad-channel amplification in the full frequency range
4 channel output data rate of 156 kHz
Fual harmonic mode in the full frequency range
On-screen 4-channel spectra acquisition
Web-interface for external communication


The eLockIn204/2 can be used as spectrum analyser, as oscilloscope, as sinus generator or as measurement control system. It provides 8 A/D channels as external inputs and controls 8 D/A channels with 156 kHz update rate as external signal outputs. It can store 32 MByte data, provides modern network connection and USB connection. Moreover, it acts as web server and all data are available over the internet.
