Each section of the command may be sent in the full or the truncated form (indicated
in upper case). The command itself may be sent in upper or lower case form.
The DLS 6700 will round any number to the nearest number permitted by the resolu-
tion of the parameter.
Sections Section 4.2 "Data Formats" and Section 4.3 "Command Syntax" give more
information on the data format and the command syntax.
4.4.1 :SETting:CHANnel:LINE <Line Number>,<Length>
Select the reach (length) of the line, where <Line Number> is the line number is a
valid line according to the model of the unit (1 to 8, 1 to 12, or 1 to 18), and
<Length> is the length of the simulated line.
The length of the DLS 6726 can be adjusted to between 1 kft and 24,000 kft in 1,000
ft increments.
For example, to set the length of line 1 to 4,000 ft, send:
:SET:CHAN:LINE 1,4000 ft
To set the length of all the lines to 4,000 ft, send:
:SET:CHAN:LINE 1,4000 ft
The units of the length are optional, but they must be in “ft” if present for the
DLS 6726. For more details on the numeric format supported by the DLS 6700, see
Section 4.2 "Data Formats".
To query the length of line currently simulated by the DLS 6700 send:
:SET:CHAN:LINE 1?
The command will return the line number, the current length followed by the unit's
minimum length, the maximum length, length incremental step size, and the gauge
(26AWG). For example, if the length of line 1 is 4 kft, and can vary from 1 to 24 kft in
1,000 ft steps, and is a 26 AWG gauge, the returned message will be:
1,4000 FT,0,24000,1000,26AWG
If there is no simulated line at the <Line Number>, then the DLS 6700 will return
“<Line NUMBER>,NONE”. For example:
17,NONE
4.4.2 :SYStem:Communicate:serial:echo <Off|On>
Set the echo off or on. For example:
:sys:comm:ser:echo on
