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 parameters
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.
