Tektronix 585 Instruction Manual page 5

General
The Tektronix Type 585 Oscilloscope is a wide range,
general purpose laboratory
accurate measurements in the d c to approximately 95 mega ­
cycle range. Plug-in amplifiers are used in the vertical de ­
flection system, permitting the instrument to be used in
many specialized applications. Any of the Tektronix Eighty
Series Plug-In Units can be used with the oscilloscope to
satisfy many types of wide-band uses. Use of the Type
81 Plug-In Adapter permits use of any of the Tektronix
letter series plug-ins for applications involving, among
others, dual trace operation, low level signals, differential
signals, pulse sampling, and transistor risetime checking.
High calibrated sweep rates allow full use of the rise-time
capabilities of the instrument.
Special circuits incorporated in the Type 585 Oscilloscope
allow accurate, continuously variable delay in the pre ­
sentation of a sweep from 1 microsecond to 10 seconds
after the receipt of a triggering impulse. The delayed sweep
feature permits highly magnified displays of a small portion
of an undelayed sweep; accurate measurements of wave ­
form time jitter; precise time measurements, as well as many
other uses.
VERT CAL DEFLECT ON SYSTEM
Characteristics for the vertical deflection system of the
Type 585 Oscilloscope depend upon the plug-in unit and
probe used with the instrument. The following character-

Sweep Rates
Time Base A
0.05 microseconds (50 nsec) to 2 seconds per centimeter
in 24 accurately calibrated steps. An uncalibrated control
permits sweep rates to be varied continuously between
50 nsec and approximately 5 seconds per centimeter.
Calibrated sweep rates are typically within 2% and in
all cases within 3%, of the indicated rate.
Time Base B
2 microseconds to 1 second per centimeter in 18 accurately
calibrated steps.
1 %, with the .2, .5, and 1 second per centimeter ranges
within 3% of the indicated rates.
Magnifier
Provides a 5 times horizontal expansion of the center 2-
centimeter portion of the oscilloscope display. It extends
the fastest Time Base A sweep rate to 10 nsec per centi ­
meter with a typical 1 % linearity.
