Delay Time And Differential Time Measurement
Accuracy (Detailed)
Delay Pickoff Jitter
Within 0.002% (less than one part in 50,000) of the
maximum available delay time when operating the instru
ment on power line frequencies other than 50 hertz.
Within 0.005% (less than one part in 20,000) of the
maximum available delay time when operating the
instrument on power line frequency of 50 hertz.
Maximum available delay time is ten times the setting of
the A TIM E/D IV switch.
Delay Range
From 0.05 microsecond or less to at least 5 seconds after
the start of the delaying (A) sweep.
X-Y OPERATION
Sensitivity
Same as vertical deflection system.
Deflection Accuracy
Same as vertical deflection system.
Variable Range
Same as vertical deflection system.
X-Axis Bandwidth
DC to 3 MHz.
Input Resistance
Same as vertical deflection system.
Input Capacitance
Same as vertical deflection system.
Maximum Usable Input Voltage
Same as vertical deflection system.
CALIBRATOR
Output
An approximate 1 kilohertz repetition rate, 30
milliampere (±2%), 300 millivolt (±1%) square-wave signal.
Z AXIS INPUT
Sensitivity
A 5-volt peak to peak signal causes noticeable
modulation at normal intensity.
Usable Frequency Range
From DC to 50 megahertz.
SIGNAL OUTPUTS
CH 2 VERT SIGNAL OUT
Output voltage is approximately 20 millivolts/division
into a 1 megohm load (approximately 10 millivolts/division
into 50 ohm load).
Bandwidth is DC to at least 50 megahertz into a 50 ohm
load.
Output DC level is approximately zero volts.
A and B +GATE Outputs
Output voltage is approximately 5 volts positive-going.
POWER SOURCE
Line Voltages
110, 115, 120, 220, 230, or 240 VAC (all ±10%)
depending on the settings of the Line Voltage Selector
switch and the Regulating Range Selector assembly, with a
