Used STANFORD RESEARCH SYSTEMS / SRS SR620 #9204970 for sale

STANFORD RESEARCH SYSTEMS / SRS SR620 is a general purpose high precision synthesized multichannel digital source that offers a combination of exceptional accuracy and stability for laboratory and industrial applications. The model features four channels, each with a range of 2 Vpp to 20 Vpp at 10 mV or 100 mV resolution with a settling time of 1 ms/V. It also provides a wide frequency range of 0.01 Hz to 20 MHz and 400 excellent frequency performance capabilities. The model uses two simultaneous pulse modulation schemes, Permanently-ON and External-Gate. Permanently-ON pulse modulation is used to provide high resolution and low noise that is ideal for laboratory applications. External-Gate pulse modulation enables SRS SR620 to generate 10 MHz pulse patterns modulated on a carrier frequency, which eliminates the need for additional hardware. The model also features a digital synthesizer with 4 decimal digits resolution, providing frequency resolution better than 1 mHz. The model's exceptional accuracy and stability is ensured by an on-board temperature- compensated crystal oscillator (TCXO). This ensures long-term precision and prevents variations due to external fluctuations. The high-efficiency switching power supply stabilizes the output voltage and further improves accuracy. The model also incorporates LAN/USB/GPIB interfaces for seamless integration into automated test and measurement systems, as well as stand-alone operation. An intuitive software package provides a user-friendly interface for controlling the instrument, setting multiple triggers, logging data, and printing reports. Overall, STANFORD RESEARCH SYSTEMS SR620 is a high precision multichannel digital synthesized source that provides exceptional accuracy and stability for laboratory and industrial applications. With four channels, a wide frequency range, excellent frequency performance capabilities, and advanced triggering options, SR620 is an ideal choice for a range of test and measurement applications.
