VXi VT1529A/B 사용자 설명서

Implied commands are those which appear in square brackets ([ ]) in the command 
syntax. (Note that the brackets are not part of the command and are not sent to the 
instrument.) Suppose a second level command is sent but is not sent preceding implied 
command. In this case, the instrument assumes that the implied command is intend 
to be used and it responds as if it was sent. Examine the INITiate subsystem shown 
below:

INITiate

[:IMMediate]

The second level command :IMMediate is an implied command. To set the 
instrument's trigger system to INIT:IMM, send either of the following command 
statements:

INIT:IMM     or     INIT

Some commands will have what appears to be a variable syntax. As an example:  
OUTPut:TTLTrg<n>:STATe ON

In these commands, the "<n>" is replaced by a number. No space is left between the 
command and the number because the number is not a parameter. The number is part 
of the command syntax. The purpose of this notation is to save a great deal of space 
in the Command Reference. In the case of …TTLTrg<n>…, n can be from 0 through 
7. An example command statement:

Parameter Types. The following section contains explanations and examples of 
parameter types that will be seen later in this chapter.

Accepts all commonly used decimal representations of 
numbers including optional signs, decimal points and 
scientific notation:
     123, 123E2, -123, -1.23E2, .123, 1.23E-2, 1.23000E-01.
Special cases include MIN, MAX, and INFinity.

A parameter that represents units may also include a
units suffix. These are:

Volts: V, mv=10

-3

, uv=10

-6

Ohms: ohm, kohm=10

3

, mohm=10

6

Seconds: s, ms=10

-3

, usec=10

-6

Hertz: hz, khz=10

3

, mhz=10

6

, ghz=10

9

The Comments section within the Command Reference
will state whether a numeric parameter can also be specified
in hex, octal and/or binary;
     #H7B, #Q173, #B1111011
