STANFORD RESEARCH SYSTEMS SR530 LOCK-IN AMPLIFIER 100 KHz SRS - 01 02 PARTS

The core of the SR530 is a precision analog sinewave multiplier. Lock-ins use a multiplier (demodulator) to translate the input signal (at the reference frequency) down to DC where it can be filtered and amplified. Many lock-ins use square wave multipliers which introduce spurious harmonic responses. The SR530 uses clean sine-wave multipliers which are inherently free of unwanted harmonics.

• 0.5 Hz to 100 kHz frequency range
• Current and voltage inputs
