WARNING

1.

ALWAYS refer to the operation manual when working near locations at which the alert mark shown on the left is attached. If the operation, etc., is performed without heeding the advice in the operation manual, there is a risk of personal injury. In addition, the equipment performance may be reduced.

Moreover, this alert mark is sometimes used with other marks and de-

scriptions indicating other dangers.

3.

This equipment cannot be repaired by the user. DO NOT attempt to open the cabinet or to disassemble internal parts. Only Anritsu-trained service personnel or staff from your sales repr.esentative with a knowledge of electrical fire and shock hazards should service this equipment. There are high-voltage parts in this equipment presenting a risk of severe injury or fatal electric shock to untrained personnel. In addition. there is a risk of damage to precision parts.

This fluid is poisonous.

DO NOT touch it, ingest it, or get in your eyes. If it is accidentally ingested, spit it out immediately, rinse your mouth with water and seek medical help. If it enters your eyes accidentally, do not rub your eyes, irrigate them with clean running water and seek medical help. If the liquid gets on your skin or clothes, wash it off carefully and thoroughly.

3.

Use two or more people to lift and move this equipment. or use a trolley.

There is a risk of back injury, if this equipment is lified by one person.

4.

This equipment uses a lithium battery to back-up the memory. This battery must be replaced by a servlce engineer when it has reached the end

of its useful life; contact the Anritsu sales section or your nearest representative.

NOTE:

5.

The main unit of the MP1777A uses lithium batteries. When d~sposing of the batteries, make sure to conform with the local regulation.

The battery used in this equ~pment has a maximum useful life of 7 years. It should be changed before this period has elapsed.

Section 3 Listener Input Format

3.2

This measuring instrument accepts the program message message. The following section explains each functional element of the program message.

3.2.1

The <TERMINATED PROGRAM MESSAGE> is defined as follows.

The <TERMINATED PROGRAM MESSAGE> constitutes a data message that incorporates all the functional elements necessary for the controller to send data. to this measuring instrument. To complete the transfer of the <PROGRAM MESSAGE>, the <PROGRAM MESSAGE TERMINATOR> is added the end of the <PROGRAM MESSAGE>.

The command tree shown in the previous section consists of the commands shown above. The section below provides explanations of the stipulations concerning descriptions of commands.

A command begins with a colon

Or, a command is structured by concatenating headers n ith a colon

Headers come in short and long forms.

The short form signifies an abbreviated form of the long form.

A

command is interpreted as the same command whether it is expressed in the short or long form. (The short and long form can be mixed.) This specification uses the uppercase and lowercase characters to distinguish the short and long forms. (The expressed in uppercase characters refers to the short foml.) However, the uppercase and lowercase characters distinguished when they are actually used.

The following section provides details of the device-specific commands.

Incidentally, the device-specific commands supported by this device are sequential commands with some exceptions An explanation is glven for commands other than sequential commands every time they come up.

When a set value by a program command causes set values for other items to become unacceptable, they will be changed to allowed values. Moreover, the measurement starts again when settings are modified during measurement. See the details execute restart.
