Specification—475
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 T IM 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.

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
