The Basic Lock-in

5.Press the <Rotate 90 deg> softkey.

Press the <deg.> softkey.

Use the knob to adjust the phase shift until Y is zero and X is equal to the positive amplitude.

Press [9] [0] [ENTER]

Press [AUTO PHASE]

6.Press <Ref. Frequency>

Press [1] [2] [.] [3] [4] [5] [EXP] [3] [ENTER]

Press [1] [0] [0] [0] [ENTER]

7.Press <Sine Output>

Use the knob to adjust the amplitude.

Press [.] [0] [1] [ENTER]

8.Press [GAIN/TC] Press [AUTO GAIN]

This adds 90° to the reference phase shift. The value of X drops to zero and Y becomes minus the magnitude (-1.000 V).

Highlight the phase shift.

The knob can be used to adjust parameters which are continuous, such as phase, amplitude and fre- quency. The final phase value should be close to zero again.

Phase shifts can also be entered numerically.

The knob is useful for small adjustments while numeric entry is easier when changing to a pre- cise value or by a large amount.

Use the Auto Phase function to return Y to zero and X to the amplitude.

Highlight the internal reference frequency menu.

Enter 12.345 kHz in exponential form. The meas- ured signal amplitude should stay within 1% of 1 V and the phase shift should stay close to zero (the value of Y should stay close to zero).

Parameters can be entered in real or integer form as well. In this case, the frequency is changed to 1.000 kHz.

The internal oscillator is crystal synthesized with 25 ppm of frequency error. The frequency can be set with 5 digit or 0.1 mHz resolution, whichever is greater.

Highlight the sine output amplitude.

As the amplitude is changed, the measured value of X should equal the sine output amplitude.

The amplitude may be entered numerically also.

The sine amplitude can be set from 4 mV to 5 V rms into high impedance (half the amplitude into a 50 Ω load).

Display the Gain and Time Constant menu.

The Auto Gain function will adjust the sensitivity so
