430 - Scitec Instruments Lock-in Amplifiers

Scitec Instruments 430 Overview

Scitec Instruments Model 430 and Model 441 are OEM analogue lock-in amplifiers. Both the single phase Model 430 and dual phase Model 441 are suitable for making amplitude and phase measurements but it is significantly easier with the Model 441. These pcb lock-in amplifiers offer a low cost solution to recovering noisy signals in many situations. Differential or single-ended input Sensitivities from 1 µV to 10 V for 1 V output High performance wide bandwidth input gain stage Low pass filter output time constants from 100 µs to 30 s 1F and 2F reference signal operation 90_ step and fine phase controlA single phase lock-in amplifier with manuel setting, using jumpers, of input mode, sensitivity, low pass filter time constant and reference signal course phase control. Sensitivity: 3 µV to 10 V in 1, 3, 10 steps for 1 V output (Gain settings of x0.1 to x330,000) Reference input: TTL/CMOS with mark/space of 1:10 to 10:1 (triggered from rising edge only) Power: -15 V, 0 V, +15 V dc at 50 mA per supply rail.
