Agilent E1441A SCPI Command Reference 81
Chapter 3
Comments • This command returns a value between “0” and “+1.0”, with “+1.0” indicating
full amplitude available (100%).
• The maximum peak-to-peak amplitude will be limited if the data points do not
span the full range of the output DAC (Digital-to- Analog Converter). For
example, the built-in “SINC” waveform does not use the full range of values
between ±1 and therefore its maximum peak-to-peak amplitude is 6.084 Vpp
(into 50 ohms).
• If you query a waveform that is not currently stored in memory, a +785,
“Specified arb waveform does not exist” error is generated.
:CATalog?
DATA:CATalog? lists the names of all waveforms currently downloaded to
memory. Returns the names of the five built-in waveforms (non-volatile memory),
“
VOLATILE” if a waveform is currently downloaded to volatile memory, and all
user-defined waveforms downloaded to non-volatile memory.
Comments • A series of quoted strings separated with commas is returned:
"SINC","NEG_RAMP","EXP_RISE","EXP_FALL",
"CARDIAC","VOLATILE","ARB_1","ARB_2"
• Use the DATA:DEL command to delete the waveform in VOLATILE memory or
any of the user-defined waveforms in non-volatile memory.
:COPY
DATA:COPY <destination arb name> [,VOLATILE] copies the waveform from
volatile memory to the specified name in non-volatile memory.
The source to be copied is always the waveform in “
VOLATILE” memory and the
"copy to" destination is always in non-
VOLATILE memory. You cannot copy to
VOLATILE memory. Therefore, the
VOLATILE parameter is optional and can be
omitted.
Parameters • The arb name may contain up to 8 characters. The first character must be a
letter (A-Z), but the remaining characters can be numbers (0-9) or the
underscore character (“ _ ”). Blank spaces are not allowed. If you specify a
name with more than 8 characters, a +783, “Arb waveform name too long”
error is generated.
• The function generator does not distinguish between upper- and lower-case
letters for the arbitrary waveform name. Therefore, ARB_1 and arb_1 are the
same name. All characters are converted to upper case.
Comments • The following built-in waveform names are reserved and cannot be used with
the DATA:COPY command: SINC, NEG_RAMP, EXP_RISE, EXP_FALL, and
