DISPlay:TRACe:PCTSPAN
Description: Set or return the vertical span (sensitivity) of the selected channel’s graph display when
using linear units in ratiometric (reference) mode. The 4530 has fixed vertical span settings
in a 1-2-5 sequence, and if the argument does not match one of these settings, it will be
forced to the next highest entry.
Syntax: DISPlay:TRACe[1|2]:PCTSPAN
Argument: = 0.1 to 10,000 %
Valid Modes: Ratiometric (reference) mode with CALCulate:UNITs =
DISPlay:TRACe:LOGCNTR
Description: Set or return the vertical center power value for the selected channel’s graph display when
using log units.
Syntax: DISPlay:TRACe[1|2]:LOGCNTR
Argument: = -100.00 to 100.00 (power in current log units)
Valid Modes: CALCulate:UNITs =
DISPlay:TRACe:LINCNTR
Description: Set or return the vertical center power value for the selected channel’s graph display when
using linear units.
Syntax: DISPlay:TRACe[1|2]:LINCNTR
Argument: = 1nW to 1MW, or 1nV to 1MV (see restrictions)
Valid Modes: CALCulate:UNITs =
Restrictions: The vert center may be no more than 100 times the value of the current vertical span setting.
DISPlay:TRACe:PCTCNTR
Description: Set or return the vertical center power value for the selected channel’s graph display when
using linear units in ratiometric (reference) mode.
Syntax: DISPlay:TRACe[1|2]:PCTCNTR
Argument: = 0.01 to 9999.99 percent
Valid Modes: Ratiometric (reference) mode with CALCulate:UNITs =
DISPlay:TEXT:BARGRAPH
Description: Set or return the visibility state of the selected channel’s bargraph display. When enabled,
the bargraph appears along the bottom of the main measurement window in dual-channel
text display mode, and gives a visual indication of the magnitude and fluctuations of the
reading. In the Model 4532 there are two independent bargraphs, one for each channel.
The bargraph value is calculated using the same settings and limits as the recorder output,
so it is possible to set the resolution and mode with the
OUTPut:RECOrder commands.
Syntax: DISPlay:TEXT[1|2]:BARgraph
Argument: = OFF, ON
Valid Modes: dual-channel text display
