Although, multiple commands can be issued as part of the read process, one
command must be specified as the actual read command. This command, when
formatted using the
<Manipulate Response>
criterion should yield an output
value in the raw output measurement unit specified for the device. Refer to the
device’s Operation and Maintenance Manual for details on remote commands.
5.5.3.4.3
Control Set Commands
Set commands are used to stimulate an output in the device. The command set
should generate an output in the
<Final Output Unit>
of the device. A voltage
controller should use these commands to set a voltage in the controller’s
<Final
Output Unit>
(typically V).
GFS Tools
automatically handles unit conversion
between the required set unit and the current testing and display unit. As with
Read command sets, multiple commands can be used. At least one command
requires the
<Process Set>
selection. This selection combines the current
remote command with a test set point to create the actual command to send to
the instrument (see 5.5.3.4.4).
Set commands typically have a command portion and a target portion. The
command portion designates that a specific set point will occur and the target
portion is the numerical set point value. The actual command and format are
device specific, so refer to the device’s manual for command details. Since the
target output will change based on test conditions, the required test command
must vary to accommodate the new target. The
<Process Set>
selection tells
GFS Tools
how to adjust the command for a given set point. The most common
choice is
<Replace [x]>
. This tells
GFS Tools
to substitute the current
numerical set point in the
<Final Output Unit>
with the text “[x]”. Commands that
require more significant manipulation are not supported by
GFS Tools
.
For example, a molbox1 uses the command “VOUT=5” to set 5 V, assuming the
molbox1 is already in voltage mode. The command “VOUT=2” is used to set 2 V.
Substitution of the value after the equals sign with the desired target will yield the
command necessary to send to the device. In this case create a command
“VOUT=[x]” in the
<Command>
field and choose the
<Replace [x]>
option as the
<Process Set>
selection.
All numeric targets are formatted for set commands according to the
specified <Final Output Unit> and <Resolution>. The range of targets is limited to
10 % of the specified <Min Output> and <Max Output> values.

Editor Options
The tables below describe the options available in the Remote Command Editor.
Not all options are available in both Read and Set command sets.
Options on the [Command] tab apply to the selected command in the
<Commands> list only and not the entire command set and not just the selected
command.
