Lock-in Amplifiers

  • Company: Scitec Instruments Ltd.
  • Type: Equipment
  • Sensitivity: 3 µV to 10 V in 1, 3, 10 Steps for 1 V Output
  • Reference Input: TTL/CMOS with Mark/Space of 1:10 to 10:1
  • Power: -15 V, 0 V, +15 V and +5 V DC at 50 mA per Supply Rail

A dual phase lock-in amplifier with manual setting, using jumpers, for input mode, sensitivity, low pass filter time constant and reference signal course phase control. Can be used in either of the following three modes:

1. Dual phase operation - one input signal with two demodulators operating 90° apart providing both X and Y (or real and imaginery) components of the input signal.

2. R calculation - on board circuitry provides the modulus of the X and Y components.

3. Single channel 1F and 2F operation - one input signal and two demodulators operating at 1× and 2× the reference frequency to measure the first and second harmonics of the input signal.
