Used STANFORD RESEARCH SYSTEMS / SRS SR650 #9201535 for sale

STANFORD RESEARCH SYSTEMS / SRS SR650 Electronic Test Equipment is a wide-band, low noise, lock-in amplifier that offers two channels of simultaneous operation. SRS SR650 is designed for applications requiring precision and accuracy due to its excellent AC and DC offset performance, high signal to noise ratio, and low input and drift noise. STANFORD RESEARCH SYSTEMS SR650 has a 0.1Hz to 100kHz frequency range and a bandwidth of 7.82Hz. Its sensitivity and signal-to-noise ratio are both 60dB, and its DC rejection is 12dB. This unit has two balanced input channels allowing for simultaneous measurement of two signals. It also features an internal clock for precise timing control. SR650 has two types of reference modes: AC and DC. AC reference mode allows a reference signal to be added to the input signal before filtering, enabling signal isolation and greater precision. DC reference mode allows for the rejection of offset voltage signals from the input. STANFORD RESEARCH SYSTEMS / SRS SR650 is equipped with a digital port for communication. This allows the unit to be connected to a PC for software control and data collection. The software control allows the user to customize the various parameters such as reference mode, filtering, gain, and offset. The data collection feature enables the user to log data or monitor multiple parameters in real time. SRS SR650 also offers digital and analog outputs. The digital output is used for communication with external devices such as PCs or remote control systems. The analog output can be used to produce a signal or measure the response of the unit to a given command. STANFORD RESEARCH SYSTEMS SR650 is highly reliable and can be used in a variety of applications. It can be used for spectrum or phase analysis, time domain analysis, lock-in analysis, or for applying gain or filter functions to a signal. It is widely used in laboratory and industrial settings due to its high precision and stability.
