Viewing Trend Charts
At power-on or following a reset (
*RST
) or instrument preset (
Preset
), numeric
data is displayed. The display can be changed to a trend chart by changing the
display mode using the command:
DISPlay[:WINDow]:MODE {NUMeric|HISTogram|TCHart}
DISPlay[:WINDow]:MODE?
(query form)
The display mode (
TCHart
) is the only trend chart parameter that can be set
programmatically (i.e. using SCPI commands). All other trend chart parame-
ters are set using the front panel .
Pressing the
Graph
key followed by the
Trend Chart
softkey starts the trend chart
from the front panel.
Trend charts correspond to all readings in reading memory for a given trigger
count (
TRIGger:COUNt
) and sample count (
SAMPle:COUNt
). If triggering is
continuous (i.e. internal), the trend chart continually updates.
Trend Chart Configuration
Figure 6-9 shows the softkey menus associated with trend chart configuration
and control of the trend window.
