Display Modes
Specifications and Characteristics
Operating Characteristics
Graticules You can choose full grid, axes, frame, or no graticule.
Number of Screens You can select 1, 2, or 4 screens.
Connect-the-Dots Provides a continuous display, connecting the
sample points with straight lines. Connect-the-dots is operative for
modes in which a single-valued waveform can be connected, including
average, envelope, single, and minimum-persistence modes.
Connect-the-dots is not available in the variable or infinite persistence
mode.
Time Base in the Repetitive Mode
Averaging You can specify the number of averages in powers of 2, up
to 2,048, On each acquisition, 1/n times the new data is added to (n-1)/n
of the previous value at each time coordinate. Averaging operates
continuously, except for the HP-IB digitize command, for which
averaging terminates at the specified number of averages.
Envelope Provides a display of the running maximum and minimum
voltage levels at each horizontal time position.
Minimum Persistence One waveform data value is displayed in each
horizontal time position of the display. The waveform is updated as new
data is acquired for a particular horizontal time position.
Variable Persistence You can vary from 500 ms to 10 seconds, the
time that each data point is retained on the display, or display the points
indefinitely by using the infinite persistence mode.
Time Base in the Real Time Mode
Single Persistence One waveform data value is displayed in each
horizontal time position. The entire waveform is replaced with each new
acquisition.
Peak Detect Displays the amplitude of pulses that have a pulse width
of 1 ns or wider regardless of the time base setting. Peak detect works in
real-time mode only at sample rates $250 MSa/s.
