The SR554 is an Amplifier from Stanford Research. An amplifier is a type of electronic test equipment that amplifies radiofrequency (RF) and microwave signals using the antenna. Amplifiers are ideal when used for electromagnetic interference (EMI) testing, cell phones, microwaves, radio communications, and other such applications.
The SR554 is a low-noise, transformer-coupled preamplifier optimized for source impedances between 0.05 W and 1 kW. With an input noise of only 0.1 nV/ÖHz, the SR554 can be used in a wide range of low-noise applications. It is the ideal preamplifier for low-temperature synchronous detection applications where isolation between the experimental sample and the lock-in amplifier is critical. The SR554 can operate in one of two modes. In the "bypassed" mode, the instrument is simply a passive transformer with a turns ratio of 100, providing an overall voltage gain of 100. In the "non-bypassed" mode, an additional amplifier with a gain of 5 is added increasing the gain to 500 and providing a low-impedance (<1 W) output. In the bypassed mode, the SR554 requires no external power. When using the output amplifier, ±20 VDC must be supplied. The preamplifier connector on SRS lock-ins can be used to power the SR554.
