Lock-In Amplifier F.A.Q.

Lock-In Amplifier F.A.Q.

+ Can I adjust the corner frequency of the low-pass filter?

Yes! It is adjustable from 237 mHz to 3.98 MHz via an iPad, Python or Matlab.

+ What is the maximum rate at which I can save data, and how many points can I save?

The sample rate is dynamically adjusted by the horizontal zoom of the display, and can be set up to the full ADC sample rate of 500 MS/s. Currently you can save 16k points for two channels simultaneously. For longer term data taking use the new data logging mode. Logging to CSV is supported at up to 1 kS/s. For faster data rates use the .li binary format which allows logging to SD card at up to 100 kS/s and logging to the Moku:Lab's RAM at up to 1 MS/s.

+ Can the Lock-in Amplifier demodulate using an external source?

Yes!! The September 2017 software update added support for direct demodulation with an external source, demodulation with a PLL (Phase-locked loop) locked to an external source, and the ability to modulate and demodulate at different frequencies.

+ Does the Lock-in include a PID controller for feedback applications?

Yes! A PID controller was added in the September 2017 update. Update your iPad App to get all the new goodies.

+ The Lock-in can readout I and Q (X and Y). What about R and theta?

Following the September 2017 free update, to switch from an X and Y readout to R and theta on the Moku:Lab App, tap the X Y block on the block diagram. The default theta gain is 0.8 V/cycle.
