DETAILED COMMAND LIST
ATTENUATION
Type:
Setting or Query
Setting Syntax:
ATT <number>
Examples:
ATT .999999
ATT 5.00001
ATTENUATION 1
Query Syntax:
ATT?
Query Response:
ATT 1
;
ATT 5;
Discussion:
The ATTENUATION command sets the input signal at-
tenuation for the selected channel to
x
1 (no attenuation) or
x 5 . The argument is rounded to an integer and if it is not a
1 or a 5 an execution error (ERR 205) is issued indicating
the argument is out of range.
The power-on initial setting is ATT 1.
For information on selecting channels see discussion of
the CHANNEL command.
ATTENUATION
Type:
Operational
Syntax:
AUTO A
B
A&B (argument is optional)
Examples:
AUTO
AUTO A
AUTOTRIG A&B
Discussion:
The AUTOTRIG command causes the DC !SO10 to auto-
matically set the trigger levels for channels to1 the approxi-
mate midpoints of the input signals. The rrlaximum and
minimum peak values for both channels are saved and may
be read out using the MAX? and MIN? queries. The
AUTOTRIG command accepts the following valid
arguments:
A
-
Automatically sets trigger level for Channel A
' - '
only. Saves minimum and maximum peak val-
ues for both channels.
B
-
Automatically sets trigger level for Channel B
only. Saves minimum and maximum peak val-
ues for both channels.
A&B
-
Automatically sets trigger levels for both chan-
nels. Also saves minimum and maximum peak
values for both channels.
If no argument is specified, AUTO A&B is assumed.
When an AUTOTRIG is performed, previously set trigger
levels for affected channels are replaced by the new values.
These new values may not be at the midpoints if the input
signals are outside the range of the instrument. Previously
measured minimum and maximum peak values for both
channels are always replaced.
The time required for the AUTOTRIG operation to com-
plete is dependent on both Channel A and Channel B ampli-
tudes and frequencies. Worst case time is alpproximately
2.5 seconds.
The following command sequence causes an AUTO
TRIGGER to be performed and the resulting tri!gger levels to
be output when the AUTOTRIG completes:
