Command Syntax
VX4792 User Manual
3-9
Note that the mnemonics and are assumed from the first header by the
headers that follow. The following command descriptions are valid examples of
commands shortened using the principle just described. (Note that the insertion
of common commands, such as , between headers does not prevent the
headers that follow from assuming the earlier header mnemonics.)
The following examples have been shortened incorrectly and cause errors.
Query Responses
The query causes the VX4792 Arbitrary Waveform Generator to return informa-
tion about its status or settings. A few queries also initiate an operation action
before returning information; for instance, the *
CAL? query runs a calibration.
If the programmer has enabled headers to be returned with query responses, the
waveform generator formats a query response like the equivalent set-command
header followed by its argument(s). When headers are turned off for query
responses, only the values are returned. Table 3–3 shows the difference in query
responses.
Table 3-3: Header in Query Responses
Query Header On Header Off
Use the command (see page 3–42) when you want the header
returned along with the information. You can save such a response and send it
back as a set-command later. Use when you want only the
information back.
