GETTING STARTED YOUR FIRST MEASUREMENTS The sample measurements described in this section are designed to acquaint the first time user with the SR850 DSP Lock-In Amplifier. Do not be concerned that your measurements do not exactly agree with these exercises. The focus of these measurement exercises is to learn how to use the instrument. It is highly recommended that the first time user step through some or all of these exercises before attempting to perform an actual experiment. The experimental

The Basic Lock-in THE BASIC LOCK-IN This measurement is designed to use the internal oscillator to explore some of the basic lock-in functions. You will need BNC cables. Specifically, you will measure the amplitude of the Sine Out at various frequencies, sensitivities, time con- stants and phase shifts. The "normal" lock-in display will be used throughout this exercise. 1. Disconnect all cables from the lock-in. Turn When the power is turned on with the backspace the power on while holding down

Synchronous filtering effectively removes output components at multiples of the detection frequen- cy. At low frequencies, this filter is a very effective way to remove 2f without requiring extremely long time constants. The outputs are now very quiet and steady, even though the time cons

Displays and Traces DISPLAYS and TRACES This measurement is designed to use the internal oscillator and an external signal source to explore some of the display types. You will need a synthesized function generator capable of providing a 100 mVrms sine wave at 1.000 kHz (the DS345 from SRS will suffice), BNC cables and a terminator appropriate for the gener- ator function output. Specifically, you will display the lock-in outputs when measuring a signal close to, but not equal to, the inter- na

Displays and Traces Press Highlight the internal oscillator frequency. Use the knob to change the frequency to By setting the lock-in reference 0.2 Hz away from 999.80 Hz. the signal frequency, the X and Y outputs are 0.2 Hz sine waves (difference between reference and signal frequency). The X and Y output dis- plays should now oscillate at about 0.2 Hz (the accuracy is determined by the crystals of the gen- erator and the lock-in). 4. Press [DISPLAY/SCALE] Display the Display a
