1 The CRT Display The analyzer's large CRT displays data, markers, limit lines, Instrument BASIC
(IBASIC) programming code, softkey menus and measurement parameters quickly and
clearly. Refer to
“Display” on page 7-16 in for more information.
2 The key simplifies measurement setups. The key allows quick
and easy selection of basic measurement parameters for a user-specified class of devices
(e.g., filters, amplifiers, or mixers). For example, when making an S
21
forward
transmission measurement or an S
12
reverse transmission measurement, selecting
Filter
as your device type puts the analyzer into narrowband detection mode,
maximizing measurement dynamic range. In comparison, selecting
Mixer
as your device
type puts the analyzer into broadband detection mode, enabling frequency translation
measurements. This capability allows new users to start making measurements with as
few as four keystrokes.
3 MEAS The measure keys select the measurements for each measurement channel. The
analyzer's measurement capabilities include S11 (reflection port 1), S21 (forward
transmission), S12 (reverse transmission), S22 (reflection port 2), power, conversion loss,
and multiport selection (for use with multiport test sets).
4 SOURCE The source keys select the desired source output signal to the device under test, for
example, selecting source frequency range or output power. The source keys also control
sweep time, number of points, and sweep triggering.
5 CONFIGURE The configure keys control receiver and display parameters. These parameters include
receiver bandwidth and averaging, display scaling and format, marker functions, and
instrument calibration.
6 SYSTEM The system keys control system level functions. These include instrument preset,
save/recall, and hardcopy output. HP-IB parameters and IBASIC are also controlled with
these system keys.
7 The Numeric Keypad Use the number keys to enter a specific numeric value for a chosen parameter. Use the
key or the softkeys to terminate the numeric entry with the appropriate
units. You can also use the front panel knob for making continuous adjustments to
parameter values, while the keys allow you to change values in steps.

Hardkeys are front panel keys physically located on the instrument front panel. In text,
these keys will be represented by the key name with a box around it such as:
.
9
Softkeys are keys whose labels are determined by the analyzer's firmware. The labels are
on the screen next to the 8 blank keys, which are located along the right edge of the
analyzer’s display. In text, these softkeys will be represented by the key name with
shading behind it such as: .
