Clearing All DEFKEYs
OUTPUT 722;"DEFKEY DEFAULT" !CLEARS ALL DEFKEYS
DEFKEY?
10 OUTPUT 722;"DEFKEY? 1" !RETURNS DEFINITION FOR KEY 1
20 ENTER 722;A$ !ENTERS DEFINITION INTO A$ VARIABLE
30 PRINT A$!PRINTS DEFINITION
40 END
A typical response returned by the above program is: "DCI 1;AZERO OFF;NPLC 0."
If nothing is assigned to DEFKEY 1, the above program returns: "DEFKEY F1."
DELAY
The DELAY command allows you to specify a time interval that is inserted
between the trigger event and the first sample event.
Syntax
DELAY [time]
time
Specifies the delay time in seconds. Delay time can range from 1E-7 (100 ns) to
6000 seconds in 10 ns increments for direct- or sub-sampling (DSAC, DSDC,
SSAC, or SSDC) or 100 ns increments for all other measurement functions.
Specifying 0 for the delay sets the delay to its minimum possible value.
Power-on time = automatic (determined by function, range, resolution and
ACBAND setting).
Default time = automatic (determined by function, range, resolution and ACBAND
setting).
Remarks
– The default delay changes automatically (unless you have specified an

alternate value) whenever you change the measurement function (DCV, ACV,
etc.), the range, the resolution, or the AC bandwidth setting (ACBAND
command).
