TRIGGERING
2213 and 2215 A Time Base Trigger Modes Normal (sweep runs when triggered), automatic (sweep runs in the absence of a triggering signal and triggers automatically for signals down to 20 Hz), and TV field (with slope set for negative going transitions, and trigger level adjusted close to blanking level, sweep starts at first line of video; use Normal for TV line display). LED indicates when sweep is triggered.
A Trigger Holdoff Adjustable control permits a stable presentation of repetitive complex waveforms.
Sensitivity Auto and Normal Internal: Below 2 MHz, signal must be at least 0.4 div amplitude; requirements increase above 2 MHz; at 60 MHz, signal must be at least 1.5 div amplitude.
Auto and Normal External Up to 2 MHz, trigger signal must be at least 50 mV p-p; requirements increase up to 60 MHz, where signal must be at least 250 mV p-p.
TV Field Composite video must be at least 2 div amplitude.
Level and Slope (Norm Mode) Internal: Trigger level can be adjusted over the range of amplitudes displayed on the CRT.  
External, Dc Coupled: Level can be adjusted over a range of at least ± 2 V, or 4 V p-p.  
External; Dc Coupled and Attenuated (divided by 10): Level can be adjusted over a range of at least ± 20 V, or 40 V p-p.
External Inputs R and C approx. 1 MΩ  paralleled by approx. 30 pF.
2215 Delayed (B) Timebase
Level and Slope Separate slope and level controls for triggering B sweep.
Sensitivity Up to 2 MHz, signal must be at least 0.4 div in vertical amplitude; requirements increase up to 60 MHz, where signal must be at least 2 div in amplitude.
X-Y OPERATION
Full Sensitivity X-Y (CH1 Horizontal, CH 2 Vertical) 2 mV/div to 10 V/div accurate ± 5%.  Bandwidth is dc to at least 2 MHz.  Phase difference between amplifiers is 3° or less from dc to 50 kHz.
DISPLAY
CRT 8 X 10 cm display.   Horizontal and vertical center lines further marked in 0.2 cm increments.  GH (P31) Phosphor standard.  10 kV accelerating potential, mesh grid, halo suppressed.
Graticule Internal, non-parallax, not illuminated; markings for measurement of risetime.
Beam Finder Compresses trace to within graticule area for ease in locating an off-screen signal.  A preset intensity level provides a constant brightness.
Z-Axis Input Dc coupled, positive-going signal decreases intensity; 5 V p-p signal causes noticeable modulation at normal intensity; dc to 5 MHz.
ENVIRONMENTAL CHARACTERISTICS
Ambient Temperature Operating: 0°C to +50°C.   Nonoperating: -55°C to +75°C.
Altitude Operating: To 4600 m (15,000 ft); maximum allowable ambient temperature decreased by 1°C/1000 ft from 5000 to 15,000 ft. Nonoperating:  15,000 m (50,000 ft).
Vibration Operating test samples were subjected to sinusoidal vibration in the X, Y and Z axis with the frequency varied from 10 Hz to 55 Hz to 10 Hz in 1 minute sweeps for a duration of 15 minutes per axis and a dwell of 10 minutes at 55 Hz.  Total displacement was 0.015 in p-p (2.4 g's at 55 Hz).
Humidity Operating and Nonoperating: Test samples were subjected to 5 cycles (120 hours) of humidity testing.
Shock Operating and Nonoperating: Test samples were subjected to 3 shocks, both directions along each axis for a total of 18 shocks.  Peak accelerations of each 1/2-sine shock were 30 g's.
