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.
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
