Signaloc™- A research grade lock-in amplifier

Designed for use in Hinds’ Exicor Systems the Signaloc is now availaible for anyone who can use a dual-phase, analog, single frequency lock-in amplifier.

You choose the frequency – any frequency between 20-200 kHz.

You choose 1f or 1f and 2f demodulation capablility*.



One User defined frequency, 20 kHz to 220 kHz range


R magnitude (V or mV RMS)

DC value (V or mV)

X – in Phase value (V or mV)

Y – Quadrature (V or mV)

Θ – Phase Angle of signal with respect to reference (degrees)



Signal Input
Gain (user selectable) 0, 3, 6, 9, 12, 15 dB
Gain Accuracy ±1% max for input signals ≥ 1 mV
±5% max for input signals ≥ 1 mV
Phase Accuracy ±3° max for input signals ≥ 1 mV
 Reference Input
       Phase Resolution 0.01°
       Reference Input Square wave "0 to 5V"

*Both the 1f and 2f must be between 20 kHz and 200 kHz. If you require demodulation of the 1f and 2f at the same time two Signalocs will be required.
