Digital noiseless lock-in amplifier

The 7124 Synchronous Detection Amplifier combines the advantages of 'old' analog instruments such as the PAR124 and the best digital instruments.


SIGNAL RECOVERY is therefore proud to introduce the model 7124 precision lock-in amplifier, which is particularly suited to such work. It uses a unique analog fiber optic link to interconnect a remote connection unit (RCU), to which the experiment is connected, and a main instrument console. In normal operation there are no digital clock signals within the RCU, and so it can emit no switching noise.
