1．PREPARATIONS BEFORE USE
1．PREPARATIONS BEFORE USE
1.1 Outline of Operation Mode 1
In ZM2376, you can switch the operation mode to use the alternative command instead of the
standard command. Use the operation mode 1 when the alternative command is easier to use for you.
However, the alternative command does not support all of the functions in ZM2376.
Operation mode 1 also provides the same operation from the panel. However, if you operate a
function unsupported by the alternative command from the panel, unintended operation may be
caused. It is recommended that you only use functions that are available from the initial settings with
the alternative command in the operation mode 1.
1.2 Switching of operation mode
The initial value of the operation mode is 0 (standard command mode).
To use the alternative command, switch the operation mode of ZM2376 to 1 (alternative command
mode). The operation mode is not initialized by the power on/off and the full initialization by the
_SHIFT_+ [INIT] key operation or from the system setting menu.
_SHIFT_+ [ SYSTEM ]
Press the _SHIFT_+ [SYSTEM] keys to display the system setting menu.

4．ALTERNATIVE COMMAND EXPLANATION
4.1 Outline of Command Language
4.1.1 Subsystem Commands
Commands are divided into groups depending on their function. Subsystem commands are arranged
in a hierarchy. The colon ( : ) is defined as the path separator.
4.1.2 Path Separator
The path separator ( : ) separates the current keyword from the keywords one level lower. In a
command character string, each colon ( : ) indicates a displacement to the path one level below the
current path.
When the colon ( : ) is found at the beginning of a command character string it means “to set the
current path to root”. The current path is also set to root by the power on, *RST command, or
message terminator. The beginning of a program message is always set to root. A colon ( : ) at the
beginning of a command character string is omissible arbitrarily.
:LEV:VOLT 1
Set current path to root (Omissible)
LEVel subsystem command (LEVel is a root command)
LEVel subsystem attached VOLTage command
A space is required between the header and the parameters
By separating the commands with a semicolon ( ; ), plural command character strings can be put
together into one program message.
:COMP:FLIM:DEV 2.2E-6, -3, +3 ; :COMP:FLIM:MODE PER
Command 1 Command 2
The above example shows one program message equivalent to the following two program
messages.
:COMP:FLIM:DEV 2.2E-6, -3, +3 Current path after execution is :COMP:FLIM:
:COMP:FLIM:MODE PER
If a colon ( :) is omitted in the second and subsequent command character strings, the
subsystem command on the same level is accessible without changing the current path.
:COMP:FLIM:DEV 2.2E-6, -3, +3 ; MODE PER In the second command string,
:COMP:FLIM: is omissible
In both cases, the program message terminator at the end is omitted.

4．ALTERNATIVE COMMAND EXPLANATION
4.1.3 Keywords Simplification
In this Instruction Manual, a keyword indicating a command or parameter is expressed with a
combination of uppercase and lowercase alphabets. Uppercase characters are used for short form
(abbreviation). Even if lowercase character part is all omitted, it has the same function as long form
that includes all the lowercase character part. However, only a part of lowercase character part cannot
be omitted.
Uppercase and lowercase characters are used only as an expedient means to explicit the form that can
be shortened but instrument makes no distinction whatsoever between the two. It is possible to use
both simultaneously.
Ex.) Command notation :DISPlay:MONItor? (Acceptable, × Error)
→:display:monitor? Long form, all lowercase character
:Disp:Moni? Short form, mixed uppercase/lowercase characters
:DISPL:MONI? × Wrong intermediary abbreviated form
:DISP:MON?× Omission over-abbreviated
4.2 Overlap Commands and Sequential Commands
Some commands allow the following commands to be executed simultaneously during execution of
them, and some commands do not allow.
Overlap commands
During execution of that command, the following command can be executed.
Sequential commands
After execution of that command finished, the following command is executed.
Note that executing multiple overlap commands will result in an operation failure.
Use *WAI, *OPC, and *OPC? commands when you do not want to execute the following commands
or query until the execution of overlap commands finished.
The commands given below are overlap commands. Other commands are all sequential commands.
Overlap commands :
:CORRection:OPEN
:CORRection:SHORt

4．ALTERNATIVE COMMAND EXPLANATION
4.3 Alternative Command Details
The function and syntax of each command shown in “Table 3-1 Common command list
(alternative command)” and “Table 3-2 Subsystem command list (alternative command)” are
explained below.
[Meaning of symbols]
• Keywords shown in square brackets ([ ]) are omissible.(Implicit Keywords)
• Curly braces ({ }) indicate parameters in the command character string.
• The vertical bar (|) indicates possibilities to select a keyword from several options.
• Comparison marks (< >) indicate that a parameter such as numerical values and
character strings need to be set.
These symbols are used for description only. They are not used in actual commands.
Description [:ABCDe][:FGHijk]:COMMandx {ON|OFF}
Actual command :ABCDe:FGHijk:COMMandx ON
[Parameters data format]

value)
4.99E+06
CRD
Character strings
ALL
SRD
Character strings in double quotation marks
"No error"
bool
Logical value
ON, OFF, 1, 0
• Unless otherwise specified individually, a numeric value in any format is accepted and it
is rounded to the nearest value if exceeding the specified resolution.
• Unless otherwise specified individually, a numeric value is set to minimum value if
below the minimum value, or set to maximum value if above the maximum value.
• For numeric value parameters in which the description is made so that MAX / MIN can
be used, a numeric value is set to maximum value if MAX (or MAXIMUM) is given, or
set to minimum value if MIN (or MINIMUM) is given.
• When the response is a numeric value, and the range, resolution and unit are omitted, it
is same as a setting. Unless otherwise specified individually, the mantissa of response in
NR3 format is 6 digits.
• For the commands in which the parameter type varies depending on the format setting,
even if a numeric value exceeding the range mentioned below is given, it is rounded to
the same range as displayed on panel or resolution. For the range of actually set value,
see the description of operation panel.
• Character strings in quotation marks are accepted in single or double quotation marks.
[Remarks]
• Both commands and queries are called commands here.
The keyword attached with “?” at the end is a query.
• Response messages to commands do not come with headers. They cannot have headers.
