Command and Query Definitions
2714 & 2715 Programmer Manual
4–27
Arguments: None,
A
,
B
,
C
,
D
This is a query with either one or no argument that returns a complex response
representing the contents of a spectrum analyzer waveform display register.
CURve?
CURve? A
CURve? B
CURve? C
CURve? D
CURVE 94,233,7,...151,2,16;
(for example)
The format of the response is determined by the previous
WFMpre
command. If
no argument is specified, the source register of the curve data is also determined
by the previous
WFMpre
command. See the
CURve
command discussion for data
formats and other details.
The
CURve?
response with
HDR ON
will resemble one of the forms shown in the
CURve
command discussion.
Data may be returned from an active or inactive register whether or not it is
saved (the register always contains data even if it is not displayed). Contrast this
function with the
FILE
command which returns a stored curve file whether or not
it is currently in a register (in binary only, and not in curve data format).
See Programming for GPIB programming examples using
CURve?
.
Arguments: Date in the form
"DD-MON-YY"
This is a command with a string argument in the above format. DD is a two-digit
day of the month, YY is the last two digits of the year, and MON represents the
first three letters of the month. This command sets the real-time clock date. The
DD and YY fields may be a single digit. If so, they are treated as if they had a
leading digit of 0. The MON field may be any mixture of uppercase and
lowercase letters. Note that these elements are separated by dashes (–), and the
quotation marks (
"
) must be present.
DATe 10-JAN-90"
