1-A softkey’s function changes as different menus are displayed. Its current function is determined by the video label to its left, on the analyzer’s screen.

2-The analyzer’s screen is divided into two main areas. The menu area, a narrow column at the screen’s right edge, displays softkey labels. The data area, the remaining portion of the screen, displays traces and other data.

3-The POWER switch turns the analyzer on and off.

4-Use a 3.5 inch flexible disk (DS,HD) in this disk drive to save your work.

5-The KEYBOARD connector allows you to attach an optional keyboard to the analyzer. The keyboard is most useful for writing and editing Agilent Instrument BASIC programs.

6- The SOURCE connector routes the analyzer’s source output to your DUT. If option AY8 (internal RF source) is installed, the conector is a type-N. If option AY8 is not installed, the connector is a BNC. Output impedance is selectable: 50 ohms or 75 ohms with option 1D7 (minimum loss pads).

7-The EXT TRIGGER connector lets you provide an external trigger for the analyzer.

8-The PROBE POWER connectors provides power for various Agilent active probes.

9-The INPUT connector routes your test signal or DUT output to the analyzer’s receiver. Input impedance is selectable: 50 ohms or 75 ohms with option 1D7 (minimum loss pads).

10-Use the DISPLAY hardkeys and their menus to select and manipulate trace data and to select display options for that data.

11-Use the SYSTEM hardkeys and their menus to control various system functions (online help, plotting, presetting, and so on).

12-Use the MEASUREMENT hardkeys and their menus to control the analyzer’s receiver and source, and to specify other measurement parameters.

13-The REMOTE OPERATION hardkey and LED indicators allow you to set up and monitor the activity of remote devices.

14-Use the MARKER hardkeys and their menus to control marker positioning and marker functions.

15-The knob’s primary purpose is to move a marker along the trace. But you can also use it to change values during numeric entry, move a cursor during text entry, or select a hypertext link in help topics

16-Use the Marker/Entry key to determine the knob’s function. With the Marker indicator illuminated the knob moves a marker along the trace. With the Entry indicator illuminated the knob changes numeric entry values.

17-Use the ENTRY hardkeys to change the value of numeric parameters or to enter numeric characters in text strings.

18-The optional CHANNEL 2 input connector routes your test signal or DUT output to the analyzer’s receiver. Input impedance is selectable: 50 ohms, 75 ohms, or 1 megohm. For ease of upgrading, the CHANNEL 2 BNC connector is installed even if option AY7 (second input channel) is not installed.
