1. LINE switch. This switch controls ac power to the analyzer. 1 is on, 0 is
off.
2. Display. This shows the measurement data traces, measurement

information areas, illustrated in
3. Disk drive. This 3.5 inch floppy-disk drive allows you to store and recall
instrument states and measurement results for later analysis.
4. Disk eject button.
5. Softkeys. These keys provide access to menus that are shown on the
display.
6. STIMULUS function block. The keys in this block allow you to control
the analyzer source's frequency, power, and other stimulus functions.
7. RESPONSE function block. The keys in this block allow you to control
the measurement and display functions of the active display channel.
8. ACTIVE CHANNEL keys. The analyzer has two independent primary
channels and two auxiliary channels. These keys allow you to select the
active channel. Any function you enter applies to the selected channel.
9. The ENTRY block. This block includes the knob, the step
keys, the number pad, and the backspace key. These allow you to enter
numerical data and control the markers.
You can use the numeric keypad to select digits, decimal points, and a
minus sign for numerical entries. You must also select a units terminator
to complete value inputs.
The backspace key has two independent functions: it modifies entries, and
it turns off the softkey menu so that marker information can be moved off
of the grids and into the softkey menu area. For more details, refer to the
"Making Measurements" chapter in the user's guide.
