Documentation Conventions
The following conventions are used throughout this document:
Instrument Identification
Throughout this manual, the terms MA24xxA/B/D and MA2400xA,
Power Sensor, or DUT (device under test) are used to refer to the power
sensor. When required to identify a specific model, the specific model
number is used, such as MA2496A. This manual’s organization is
displayed in the table of contents.
Hard Keys or Front Panel Keys
When testing sensors, the power meter and test equipment front panel
hard keys are denoted with a bold Sans Serif font such as “Press the
front panel Frequency key.”
User Interface, Menus, and Soft Buttons
The power meter user interface consists of menus, button lists,
sub-menus, toolbars, and dialog boxes. All of these elements are denoted
with a special font, such as the Calibration menu or the AutoCal button.

1-3 Instrument Care Chapter 1 — General Information
User Interface Navigation Conventions
Navigation in Power Meter and Test Equipment: Elements in
navigation shortcuts or paths (identified as “Navigation”) are separated
with the pipe symbol (“|”). Menu and dialog box names are distinctive
Sans Serif font. Button names are in Title Case. For example, you would
enter the power meter Service Mode by pressing the front panel keys in
the following sequence:
System | Service | Diag | 0 | Enter:This string means you would: press
the System hard key |press the Service soft key |press the Diag soft
key |press the 0keypad hard key |Press the Enter soft key.
1-3 Instrument Care
Instrument care and preventive maintenance consist occasional
cleaning of the instrument, inspecting and cleaning the RF connectors
and all accessories before use..
Connector Care
Clean the instrument with a soft, lint-free cloth dampened with water
or water with a mild cleaning solution. Clean the RF connectors and
center pins with a cotton swab dampened with denatured alcohol.
Visually inspect the connectors. The fingers of the female connectors
and the pins of the male connectors should be unbroken and uniform in
appearance. If you are unsure whether the connectors are undamaged,
gauge the connectors to confirm that the dimensions are correct.
Visually inspect the test port cables. The test port cable should be
uniform in appearance and not stretched, kinked, dented, or broken.
Visually inspect connectors for general wear, cleanliness, and for
damage such as bent pins or connector rings. Repair or replace damaged
connectors immediately. Dirty connectors can limit the accuracy of your
measurements. Damaged connectors can harm the instrument.
Connection of cables carrying an electrostatic potential, excess power, or
excess voltage can damage the connector, the instrument, or both.
Caution
Do not operate or store the power measurement equipment
in extreme environments. Refer to the instrument Technical
Data Sheet for the specified operating and storage
conditions,
