Standard/User Defined Softkey
Standard uses the IEEE measurement points for all measurements. Figure
13-1 shows some of the standard measurement thresholds. User defined
allows you to customize the measurements for your specific applications.
Thresholds/Measurements Softkey
Threshold settings apply to all user-defined front panel measurements.
Thresholds sets the measurement points for all timing measurements.
Thresholds You canuse the percent /volts softkey to set the
thresholds as a percentage of the calculated top and base, or as a specific
voltage.
e The percentage range is from —25% to +125%
e Voltage levels from -250 kV to +250 kV
The data source softkey allows you to select a source that the upper and
lower thresholds track. You can select any channel, function, or memory was
a source, and you can set the thresholds individually for any source. For
example, you can set the thresholds for channel 1 as 10%/90%, and you can
set the thresholds for channel 2 as 20%/80%.
