Measurement and Display Functions
Time Markers Two vertical markers, X and O, are provided for measurements of time
and voltage. Capabilities are: measure voltage at point where X and O markers cross each
analog waveform; measure time from trigger to X, trigger to O, and X to O; automatic
marker placement by specifying percentage of edge, edge number, and rising or falling
edge type; run until X to O > than, < than, in range, and not in range provides selective
event search; X to O statistics (mean, max, and min) provide analysis of time interval
deviation.
Voltage Markers Two horizontal markers, A and B, are provided for voltage
measurements. These markers can each be placed on any acquisition channel trace. A
delta voltage display provides delta V between markers on the same channel or between
channels.
Automatic Search Searches for a percentage voltage level at a positive or negative
edge, count adjustable from 1 to 100.
Auto Search Statistics Mean, maximum, and minimum values for elapsed time from X
to O markers for multiple runs. Number of valid runs and total number of runs available.
Automatic Measurements The following pulse parameter measurements can be
performed automatically:
Frequency Rise time + pulse width
Period Fall time −pulse width

Overshoot
(*gives difference between top and base voltages; only available over bus)
Grid Graticules can be displayed in background of waveform.
Setup Aids
Autoscale Autoscales the vertical and horizontal ranges, offset, and trigger level to
display the input signals. Requires a frequency between 50 Hz and 250 MHz.
Presets Scales the vertical range, offset, and trigger level to predetermined values for
displaying ECL or TTL waveforms.
Calibration Vertical, trigger, delay, and all defaults. Calibration factors stored in
NV-RAM on the circuit board.
Probe Compensation Source External BNC supplies a square wave approximately 0.0
mV to -800 mV into the open circuit at approximately 1000 Hz.
