Lock-in amplifier - Signaloc™


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 Resolution0.01°
       Reference InputSquare wave "0 to 5V"

Output Filter Time Constants (user selectable)4, 10, 18, 32, 64, 132, 260, 516 mSec
