i) TRACe subsystem

TRACe:CATalog?
This returns a list of defined waveform names. This command returns a list of all waveform names
that can be selected by the user.
Syntax:
TRACe:CATalog?
Parameters: None
Query example: TRAC:CAT?
Response format: <CRD>[, <CRD>]
Response example: SIN, SQU, ARB1, ARB2, ARB3, ARB4, ARB5, ARB6, ARB7, ARB8,
ARB9, ARB10, ARB11, ARB12, ARB13, ARB14, ARB15, ARB16

TRACe[:DATA]
This sends or receives arbitrary waveforms. When a waveform name (ARB1 to ARB16) is
selected as the first parameter, the subsequent parameters are used to send 2 bytes × 4096 words (=
8192 bytes) of waveform data in big endian order (one word of waveform data is sent in 2’s
complement format, higher byte first and then lower byte). As in the command example,
everything from the command to the data should be sent at one time.
However, the waveform data must be 4096 words.
The effective range for waveform data is

16384 to 16383. If a value of

16384 or lower is input,
it is recognized as

16384. If a value of 16383 or higher is input, it is recognized as 16383.
It can not be available for RS232 interface. (Use USB interface.)
