OUTPut is the root keyword of the command; FILTer and STATe are
second level keywords. LPASs is third level keyword. A colon ( : )
separates a command keyword from a lower level keyword.
Command Format
The format used to show commands in this manual is shown below:
FREQuency
{<frequency>|MINimum|MAXimum}
The command syntax shows most commands (and some parameters)
as a mixture of upper and lowercase letters. The uppercase letters
indicate the abbreviated spelling for the command. For shorter
program lines, send the abbreviated form. For better program
readability, use the long form.
For example, in the above syntax statement, FREQ and
FREQUENCY are both acceptable forms. Use upper or lowercase
letters. Therefore, FREQ, FREQUENCY, freq, and Freq are all
acceptable. Other forms such as FRE and FREQUEN will generate an
error.
The above syntax statement shows the frequency parameter
enclosed in triangular brackets. The brackets are not sent with the
command string. A value for the frequency parameter (such as
"FREQ 50e+6”) must be specified.
Some parameters are enclosed in square brackets ([]). The brackets
indicate that the parameter is optional and can be omitted. The
brackets are not sent with the command string.
Command
Separator
A colon ( : ) is used to separate a command keyword from a lower
level keyword as shown below:
SOUR:FUNC:SHAP
SIN
A semicolon ( ; ) is used to separate commands within the same
subsystem, and can also minimize typing. For example, sending the
following command string:
TRIG:SLOP NEG;COUN 10;TIM 5e-3
is the same as sending the following three commands:
:TRIG:SLOP NEG
:TRIG:COUN 10
:TRIG:TIM
5e-3
Use the colon and semicolon to link commands from different
subsystems. For example, in the following command string, an error is
generated if both the colon and the semicolon are not used.
OUTP:STATE ON;:TRIG:BURS ON
The MIN and MAX
Substitute MINimum or MAXimum in place of a parameter for some
commands. For example, consider the following command:
