Operating over a frequency range of 0.5 Hz to 100 kHz, it features low-noise voltage and current inputs, up to 80 dB of dynamic reserve, two stages of time constants, and an internal oscillator. The SR530 is equipped with both IEEE-488 (GPIB) and RS-232 interfaces, four rear-panel ADC inputs, two DAC outputs, and a built-in ratio feature, making it highly suitable for sensitive signal recovery in research and laboratory automation environments.\u003c\/p\u003e\n\u003ctable style=\"width:100%;
