Stanford Research SR552 Bipolar Preamplifier
$245.00Untested Stanford Research SR552 Bipolar Preamplifier
The SR552 Voltage Preamplifier is designed to work
with SRS lock-in amplifiers, providing gain where it is
needed most—right at the experiment. The preamplifier .
minimizes noise and pickup in the connecting lines and can
reduce measurement time in noise-limited experiments. The
SR552 has a bipolar front-end design (100 kΩ impedance,
1.4 nV/√Hz noise). Power and control signals are brought
from the lock-in by a 9-pin cable (not included). The SR552 may
also be operated independently by applying appropriate power
supply voltages (±20 VDC, +5 VDC).
