Horizontal Display Modes		A, mixed sweep, A intensified, B delayed. B ends A for increased intensity in the delayed mode.
Calibrated Mixed Sweep		Displays A sweep for period determined by delay-time position control, then displays B sweep for remainder of horizontal sweep.
CALIBRATED SWEEP DELAY
Delay Time Range		465: 0.2 to X10 delay time/div settings of 200/ns to 0.5 s (minimum delay time is 200 ns). 475/475A: 0 to X10 delay time/div settings of 50 ns to 0.5 s (minimum delay time is 50 ns).
Differential Time Measurement Accuracy		Delay Time Setting				+15°C to 35°C
		Over one or more major dial divisions				± 1%
		Less than one major dial division				± 0.01 major dial division
Jitter		1 part or less in 50,000 (0.002%) of 10X the A sweep time/div setting. 1 part in 20,000 when operating from 50 Hz line.
TRIGGERING A AND B
A Trigger Modes		Normal (sweep runs when triggered). Automatic (sweep free-runs in the absence of a triggering signal and for signals below 30 Hz). Single sweep (sweep runs one time on the first triggering event after the reset selector is pressed). Lights indicate when sweep is triggered and when single sweep is ready.
A Trigger Holdoff		Adjustable control permits a stable presentation of repetitive complex waveforms.
B Trigger Modes		B runs after delay time (starts automatically at the end of delay time) and B triggerable after delay time (runs when triggered). The B (delayed) sweep runs once, in each of these modes, following the A sweep delay time.
