6. Press <Monitor> to select Input/Output.

7. Press <Format> to select Single.

8.Press [REF/PHASE] Press <Ref. Frequency>

Use the knob to adjust the frequency slowly to try to stop the rotation of the signal vector.

9.Use a BNC cable to connect the TTL SYNC output from the generator to the Reference Input of the lock-in.

Press <Ref. Source>

Use the knob to select External.

In this case, set the bar graph to ±180°. The bar graph should be a linear phase ramp at 0.2 Hz.

The monitor display at the top of the screen moni- tors either the lock-in settings (sensitivity, time constant, etc.) or the measured lock-in inputs and outputs (X, Y, R, θ and Aux In 1-4).

The Input/Output monitor allows you to see all of the measured quantities, even if they are not shown on the larger displays.

The screen is now setup for a single display. The default display type for the full screen display is a polar graph.

The polar graph plots the quantities X and Y on an X-Y axis. The resulting vector has a length equal to the magnitude R and has a phase angle relative to the positive X axis equal to θ. In this case, since the phase is rotating at the difference frequency, the vector rotates at 0.2 Hz.

Display the Reference and Phase menu.

Highlight the internal oscillator frequency.

As the internal reference frequency gets closer to the signal frequency, the rotation gets slower and slower. If the frequencies are EXACTLY equal, then the phase is constant.

By using the signal source as the external refer- ence, the lock-in will phase lock its internal oscilla- tor to the signal frequency and the phase will be a constant.

Highlight the reference source.

Select external reference mode. The lock-in will phase lock to the signal at the Reference Input.
