This section contains information about the response of the switchbox
instrument to three IEEE 488.2 common commands.
The
numeric_state
*SAV <
The state number (0-9) is specified by the numeric_state parameter.
The settings saved by this command are:
•
ARM:COUNt
•
TRIGger:SOURce
•
OUTPut:STATe
•
INITiate:CONTinuous
•
(the scan list is set to invalid; therefore, the command does
SCAN
not save a scan list.)
•
SCAN:MODE
•
SCAN:PORT
The
*RCL <
numeric_state
was executed for the specified numeric_state parameter (0-9). If no
was executed for the numeric_state,
to the
settings list for the settings recalled by
*SAV
The
*RST
command opens all channels, invalidates the current channel list
for scanning, and sets the following:
•
ARM:COUNt 1
•
TRIGger:SOURce IMM
•
INIT:CONTinuous OFF
•
OUTPut OFF
•
SCAN:MODE NONE
•
SCAN:PORT NONE
The
query requests a value from the instrument's error
SYSTem:ERRor?
register. This register contains an integer in the range [-32768 to 32767].
The response takes the following form:
<err_number>,<err_message>
The <err_number> is the value of the instrument's error register. The
<err_message> is a short description of the error, followed by further
information about the error.
If no error occurs, the switchbox responds with 0,"No error". If there has
been more than one error, the instrument will respond with the first one in
its error queue. Subsequent queries continue to read the error queue until it
is empty. The maximum <err_message> string length is 255 characters.
