eLockIn203
- digital quad-phase "DSP" Lock-In Amplifier -
The eLockIn203 lock-in amplifier is "the little brother" of the eLockIn204.
It has several parameters and features which are only found in
these Anfatec instruments.
The most unique are:
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
dual input/dual harmonic mode in the full frequency range
on-screen 4-channel spectra acquisition
web-interface for external communication
The eLockIn203 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 >150 MB data,
provides modern network connection and USB connection.
Moreover, it acts as web server and all data are available over the internet.
