We have written the exercisesin this chapter to prepare the function

15、generator for use and help you getfamiliar with some of the front-panel operations.The front panel has two rows of keys to select various functions andoperations. Most keys have a shifted function printed in blue above thekey. To perform a shifted function, pressShift （the Shift annunciator willturn

16、 on）. Then, press the key that has the desired label above it. Forexample, to select the AM （amplitude modulation） function, pressAM （the shifted version of the key）.If you accidentally press , just press it again to turn off the Shiftannunciator.Most keys also have a number printed in green next to

17、 the key. To enablethe number mode, pressEnter Number （the Num annunciator will turn on）.Then, press the keys that have the desired numbers printed next to them.For example, to select the number “10, press 1 （next to the and Recall keys）., just press Cancel to turnoff the Num annunciator.To set the

18、output frequencyAt power-on, the function generator outputs a sine wave at 1 kHz withamplitude of 100 mV peak-to-peak （into a 50 termination）.The following steps show you how to change the frequency to 1.2 MHz.1 Enable the frequency modify mode.Press FreqThe displayed frequency is either the power-o

19、n value or the previousfrequency selected. When you change functions, the same frequency isused if the present value is valid for the new function.1.000,000,0 KHz2 Enter the magnitude of the desired frequency. or use the knob and arrow keys to changethe number.Notice that the Num annunciator turns o

20、n and “ENTER NUM flashes onthe display, indicating that the number mode is enabled.To cancel the number mode, press .3 Set the units to the desired value.Press （MHz/mVpp）The units are selected using the arrow keys on the right side of the frontpanel. As soon as you select the units, the function gen

21、erator outputs thewaveform with the displayed frequency. To turn off the flashing digit,move the cursor to the left of the display using the arrow keys.1.200,000,0 MHzTo set the output amplitudeAt power-on, the function generator outputs a sine wave with amplitude of 100 mV peak-to-peak （into a 50_
