Front Panel Description
Front Panel Description
The hardkeys, softkeys and menus, RPG knob and step keys, and front
panel inputs are explained below.
Softkeys either activate a feature or access a further softkey menu.
There are seven softkeys. The softkey which is currently active is
highlighted. Softkeys which are not available for use are greyed-out.
The transmitter tester uses five types of softkey:
• Menu softkeys. An arrow on the right side of a key label indicates
that the key accesses a further menu.
• Toggle softkeys. A toggle softkey allows you to select between one of
several settings (usually two settings, but there may be more) that
are shown on a softkey; the available settings are listed underneath
the softkey label, and the currently active setting is underlined.
Pressing the toggle softkey will result in activating a setting that is
adjacent to the initial, underlined setting.
• Numeric softkeys. A numeric softkey allows you to modify a
numerical value. Current values are shown in the active function
area of the display.
• Numeric + Toggle softkeys. A numeric + toggle softkey allows you,
first, to toggle between an automatic or manual mode, and then, if
you have selected manual, allows you to enter a numeric value.
• Immediate action softkeys. An immediate action softkey activates a
feature immediately upon being pressed.
Softkey menus are dependent on the measurement chosen or the front
panel key that has been activated. Many softkey menus contain more
than seven softkeys, and cannot be displayed on a single-page menu.
Multiple page menus are accessed by pressing a
the bottom key of the menu.
Paths to access any feature will be found in the key access table on
page 53. Display annotation is explained on page 35. Operation of the
3.5 inch floppy-drive is covered in the section on printing on page 73.

vertical scale functions in units of dBm, dB, volts,
degrees, or radians. The parameters in this menu
apply only to the active window in the current
measurement. See page 87 for more detail.
3. Input key The
Input key accesses softkeys that control the input of
the transmitter tester. These affect all measurements
within the current mode. Note that the internal
50 MHz reference signal and the IF align signal are
used as internal inputs that do not require external
connections. See page 65 for more detail.
4. View keys
View keys modify the format of the trace and numeric
data on the display. See page 87 for more detail.
•
View/Trace accesses softkeys that control the way
results are viewed.
• Display accesses softkeys that change the display.
Functions such as limit mask on/off and dots on/off
are available for some measurements.
5. Measure keys are used to select and set up a specific
measurement within the selected application. See page
83 for more detail.
•
MEASURE accesses softkeys that select and initiate
the various measurements that are specific to the
current mode.
•
Meas Setup accesses the setup parameters that are
specific to the current measurement.
• Restart causes the measurement that is currently in
process to stop, then start again at the beginning
according to the current measurement setup
parameters.
•
Meas Control accesses softkeys that affect the
measurement after it has been setup, for example
selecting a single or continuous measurement.
6. Mode keys select the measurement mode and mode parameters
such as input and trigger settings. See page 77 for
more detail.
•
MODE accesses softkeys to select the instrument
mode. Each mode is independent of all other modes.
• Mode Setup accesses softkeys that affect parameters
that are specific to the current mode and affect all
measurements within that mode.

7. System keys access system features, that are used with all
instrument modes. See page 52 for further explanation
of system features.
•
System accesses features that control instrument
configuration at the system level, like I/O
configuration and alignment, which affect all
instrument modes. Pressing
System also returns the
instrument to local control, if it has been in remote
mode.
•
Preset resets all parameters of the current mode
back to the factory defaults.
• Print immediately prints what is on the screen to the
printer, or saves a file to a floppy disc, according to
the parameters that are currently set in the
Setup menu. See page 73 for more detail.
Print Setup configures the transmitter tester for
•
printing to a printer, or saving an image file to the
floppy disc drive, and also allows you to select the
printer type.

•
File accesses softkeys that control the file system of
the transmitter tester for saving and loading
instrument states. See page 71 for more detail.
•
Save saves the current instrument state in the File
menu. See page 71 for more detail.
8. Marker keys are used to obtain specific information about parts of
the displayed measurement (for example, to identify
the exact frequency of an offset). See page 89 for more
detail.
•
Marker accesses softkeys that allow manual
positioning of markers.
• Search automatically performs a peak search, and
accesses softkeys that automatically position
markers at preset locations on the trace (for
example, to determine the difference between the
amplitude of one peak and another).
9. Probe Power The probe power input supplies power for external
probes; the three connectors are a ground, and a +15 V,
and a −12.6 V connector. The probe power supplies
power to high frequency probes and accessories, such as
preamplifiers, that are used as accessories to the
transmitter tester. The probe power provides a
maximum of 150 mA.

10. RF Input The 50 Ω RF input allows for input of an external RF
signal. The connector is a type N female, and is rated
for a maximum input of +35 dBm for measuring a CW
signal, and a maximum of 26 volts for a DC signal.
11. Data Entry keys are used to enter numeric values. Entries made
using data entry keys will be visible in the active
function area (see the section on annotation on page 35
to locate the active function area).
• The
Enter key is used to terminate numeric data
where no units of measurement are being entered,
or where you want to terminate with the default unit
of measurement. For operations involving selection
of a unit of measurement (for example, dB, dBm,
Hz, s, degrees, radians), the
Units softkey menu
(explained below) is used to terminate numeric
entries.
•
Units softkeys are used to enter units of
measurement. If the value you are entering is in
units of measurement, the units softkey menu will
automatically appear once you enter a digit. After
entering the desired numeric value, you terminate
the entry by pressing the appropriate units of
measurement softkey.
•
Numeric keys enter numeric values as indicated on
the keys. In addition, decimal and positive and
negative sign keys are available for your use.
• The
Step keys (these are the up and down arrow
