# Lock-in Amplifier

This instrument features a dual-phase demodulator with cascaded single pole low-pass filters to attenuate the second harmonic and suppress noise in each quadrature

If you are directly using the RESTful API (e.g. using cURL), the instrument name as used in the URL is lockinamp.

Data Logger

Data Streaming

Input PLL

  • pll_reacquire: Triggers a reacquisition cycle on the embedded PLL
  • set_pll: Sets the frequency acquisition/configuration and tracking bandwidth of the PLL.

Oscilloscope

  • enable_rollmode: Enables and disables Roll Mode X-axis behaviour
  • get_data: Get a frame of the data from the instrument
  • getters: Lock-in Amplifier - Oscilloscope - getter functions
