SWEEP

Commands in order to modify SWEEP parameters.
Syntax :
:FREQuency:MODE SWEep
:FREQuency :MODE FIXed | CW
:FREQuency :MODE ?
Sending line (1) the SWEEP can be turned on.
Sending line (2) the SWEEP can be turned off, if SWEEP is
present.
Sending line (3) the instrument returns the current SWEEP
state. It sends back SWE, if SWEEP is in progress, and FIX, if
no SWEEP is present.
:FREQuency:STARt <NUM>
:FREQuency:STARt?
:FREQuency:STOP <NUM>
:FREQuency:STOP?
Sending line (4) and (6) the two frequencies START and STOP
can be changed. The <NUM> parameter is a NR1 or NR2 or
NR3 number (see paragraph Syntax conventions). No unit
must follow the number, Hz unit is the default one. The value
is rounded to the resolution.
Sending line (5) and (7) the instrument returns the two frequen-
cies START and STOP. It sends back a string representing a
NR3 decimal number.
:SWEep :TIME <NUM>
:SWEep :TIME?
Sending line (8) the SWEEP TIME can be changed. The <NUM>
parameter is a NR2 number (see paragraph Syntax conven-
tions). No unit must follow the number, sec. unit is the default
one. The value is rounded to the resolution.
Sending line (9) the instrument returns the SWEEP TIME. It
sends back a string representing a NR2 decimal number.
Example:
:SWE :TIME 5;:FREQ:STAR 16E+6;:FREQ:STOP 1.2E+9;
:FREQ :MODE SWE

SYSTEM

Syntax:
:SYSTem:ERRor?
Sending this line the instrument returns the current error code.
This code is the first one recorded even if several errors have
occured. After sending the error number the instrument sets
it to zero (it also set it to zero at power on time). Refer to the
table of the error codes.
Notes regarding the syntax
As mentioned in some examples above, in each command line
the first character ":" is optional. In case of successive com-
mands corresponding to the same tree it is not necessary to
repeat all the descriptions of the commands.
Example:
FM:INT:FREQ 9E+3; SHAP SIN; DEV 150E+3; STAT ON
is the same as:
44
Subject to change without notice
:FM:INT:FREQ 9E+3; :FM:INT:SHAP SIN; :FM:DEV 150E+3;
STAT ON
In fact: FM for the first command indicates that we get into the
(1) FM tree (group) and the following commands, if they belong to
(2) the same group, may be shorter (without repeating all the tree
(3) descriptions). If the next command does not belong to the same
tree, it is necessary to specify the root.
