Chapter 1
Getting Started
The tutorials in this chapter are designed to acquaint the first time user with the SR844 RF Lock-In
Amplifier. The functions and features of the SR844 are grouped together into several short tutorials. You
may choose to do the tutorials selectively depending on your level of experience and your measurement
needs. Do not be concerned that your measurements do not agree exactly with the printed values in the
manual; the focus of these exercises is to learn how to use the instrument.
For all of the tutorials it is expected that you have installed the instrument with the line voltage setting
appropriate to the AC power available. If you have not done so, please see the section
Line Voltage
Selection under Safety and Preparation for Use (page i) before proceeding further.
The experimental procedures are detailed in two columns. The left column lists the actual steps to be
performed. The right column is an explanation of each step. The front panel
Keys , Knob and
READOUTS are denoted in special fonts. Indicators are shown in Bold and connectors in CAPITALS.
