- Page 17 However, the Time base menu has at least two of this type of softkey, Bit Rate (Agilent 83480A only) and Scale and Position. In this case, only one of the softkeys is active at a time. To make the other softkey active, you must press the corresponding softkey.
- Page 18 Introducing the Instrument A Quick Tour of the Front Panel You change selections by pressing the Hysteresis softkey, which brings up a sec- ond level softkey menu on the display. Then, you use the softkeys, arrow keys, or knob to change selections. To activate that selection, press the Enter softkey, then the display returns to the previous softkey menu.

Page 21: Equipment Used In These Exercises
Equipment Used in These Exercises All of the pictures of the display in this book were generated using an Agilent 83480A with an Agilent 83483A, 54751A electrical plug-in module, and the signal from the Agilent 8133A pulse generator. If you are using a different plug-in module or signal source, your display and instrument settings may vary from the pictures in this book. -
Page 22: Exercise 1. Installing A Plug-In Module
Operating the Instrument Exercise 1. Installing a Plug-in Module Exercise 1. Installing a Plug-in Module The purpose of a plug-in module is to provide measurement channels, includ- ing sampling for the mainframe. A plug-in module scales the input signal, sets the bandwidth of the system, and allows the offset to be adjusted so the signal can be viewed. -
Page 23: Exercise 2. Turning On The Instrument
If the display is blank or if the message, Power-On Test Failed, appears at the top of the display, refer to Chapter 3, “In Case of Difficulty” or to the optional Agilent 83480A, 54750A Service Guide. -

Page 25: Exercise 4. Finding The Signal
Operating the Instrument Exercise 4. Finding the Signal Exercise 4. Finding the Signal The purpose of this exercise is to demonstrate the Autoscale function. The Autoscale function can be used to automatically set up the display for most input signals. To activate the Autoscale function, press Autoscale. -
Page 26: Exercise 5. Modifying The Setup
Operating the Instrument Exercise 5. Modifying the Setup Exercise 5. Modifying the Setup The purpose of this exercise is to show you the Channel and Time Base menus. Changing the vertical scale 1 To display the Channel menu and change the vertical scaling, press: Channel (located on the plug-in module), Scale Change the scaling so the vertical height of the signal is about eight divisions, using the knob, arrow keys or keypad. - Page 27 Operating the Instrument Exercise 5. Modifying the Setup Using the keypad When using the Agilent 83483A, 54751A electrical plug-in module, the knob or arrow key changes the scaling from 50 mV/div to 100 mV/div, in one step. At 50 mV/div the signal is clipped, and at 100 mV/div the signal is not expanded to take advantage of the full vertical size of the display.
- Page 28 Operating the Instrument Exercise 5. Modifying the Setup Figure 2-2. Signal vertical display Note — Agilent 83480A only You can automatically adjust the vertical scale, instead of following the preceding pro- cedure by pressing: Channel, Channel autoscale The amplitude scale is optimized for the input signal while the timebase settings are left alone.
- Page 29 Operating the Instrument Exercise 5. Modifying the Setup Using the keypad 6 When the knob and arrow keys are not in the Fine mode, they operate in a 1-2-5 sequence, changing the scale from 5 ns/div to 2 ns/div in one large step. You can use Fine mode so the knob and arrow keys adjust in smaller increments, or you can use the keypad to enter a smaller value, like 1.4 ns/div.

Refer to the Agilent 83480A, 54750A User’s Guide for more information on making automatic measurements. - Page 32 Operating the Instrument Exercise 6. Making Measurements on the Signal Positioning the markers 4 To position the X1 marker, press: X1 Position Set the X1 marker to the left edge of the pulse. 5 To position the X2 marker, press: X2 Position Set the X2 marker to the right edge of the pulse.
- Page 33 Operating the Instrument Exercise 6. Making Measurements on the Signal Notice the ∆X and ∆Y at the bottom of the display. The ∆X value is the width measurement, and the ∆Y value is the amplitude measurement. The markers allow you to make custom measurements on signals. Remember, they are not tied directly to the waveform data stored in memory, they are just positions on the display.
