DATA?
Query :DISPlay:DATA? [<format>[,<area> [,<image>]]]
Returns an image of the current display in the specified file format. If no arguments are spec-
ified, the default selections are PCX file type, SCReen mode, and inversion set to INVert. The
BMP and JPG file formats are the only formats that are saved with 24 bit color and provide
the highest quality image.
Arguments The <format> argument is the file format: BMP | PCX | EPS | PS | GIF | TIF | JPG. The <area>
argument selects the screen area to be saved to disk: {SCReen | GRATicule}. GRATicule
selects only the graticule area of the display screen is saved; the entire screen is saved if you
select the default setting SCReen. <area> selects the display setting: SCReen | GRATicule.
The <image> argument specifies the color scheme used during the screen save operation:
{NORMal | INVert | MONochrome}. The default value is INVert which saves the waveforms
over a white background.
Returned Format [:DISPlay:DATA] <binary_block_data><NL>
Data is returned in the IEEE 488.2 definite block format.
DCOLor (Default COLor)
Command :DISPlay:DCOLor
Resets the screen colors to the predefined factory default colors and resets the grid intensity.
Example 10 OUTPUT 707;":DISPLAY:DCOLOR"
GRATicule
Commands :DISPlay:GRATicule {GRID|FRAMe}
:DISPlay:GRATicule:INTensity <intensity_value>
Select the type of graticule that is displayed. 86100A analyzers have a 10-by-8 (unit) display
graticule grid that you can turn on or off. When the grid is on, a grid line is place on each ver-
tical and horizontal division. When it is off, a frame with tic marks surrounds the graticule
edges.
<intensity_value> A number from 0 to 100, indicating the percentage of display intensity. You can dim the grid's
intensity or turn the grid off to better view waveforms that might be obscured by the grati-
cule lines. Otherwise, you can use the grid to estimate waveform measurements such as
amplitude and period. When printing, the grid intensity control doesn't affect the hardcopy.
To remove the grid from a printed hardcopy, you must turn off the grid before printing.
Example This example sets up the analyzer's display background with a frame that is separated into
major and minor divisions.
10 OUTPUT 707;":DISPLAY:GRATICULE FRAME"
Queries :DISPlay:GRATicule?
:DISPlay:GRATicule:INTensity?
The queries return the type of graticule currently displayed, or the intensity, depending on
the query you request.
