The minimum time constant is 1? Our newest lock-in amplifiers have achieved high-frequency and high speed response. This is an integer-period moving-average filter.

Ripple caused by detection is greatly reduced, and the output is nearly settled in the averaging interval (integer period), so the time constant can be reduced (to obtain faster response). It takes just about two cycles to lock on to the reference signal even at low frequencies. Furthermore, a moving average filter synchronized with the signal cycle obtains a high-speed response with a small ripple.

Phase detection and subsequent processing are performed digitally. Output zero drift at high gains is smaller than the analog system, and up to 100 dB dynamic reserve can be obtained (measurement can be performed with a noise 100,000 times larger than the sensitivity, namely the signal full scale). Voltage measurement range: 10nV min.

Current measurement range: 10fA min. Dual phases and Dual frequencies measurement. Built-in power supply to drive NF low noise amplifier.

Built-in signal oscillator that can be used as a REF signal. Input noise: 4.5nV /?

Dynamic reserve: 100 dB or more. Harmonic measurement: Up to 63rd order, with fraction setting. Measurement parameters: X, Y, R, ?

Analog output: Outputs 4 selected from measurement parameters. Data memory: Temporarily store measurement data in 3 memory buffers. Remote control: USB, RS-232, GPIB, LAN. Frequency response: 0.5Hz to 11MHz. Time constants setting: 1µs to 50ks. Voltage input sensitivity: 10nV to 10V. Current input sensitivity : 10fA to 1µA.
