SECTION I
CHARACTERISTICS
Introduction
The Type 544 Oscilloscope is a versatile laboratory instru
ment designed for use with all Tektronix lettered- or 1-Series
plug-in units.
Vertical Deflection System
The plug-in unit and probe used with the Type 544 deter
mine the overall characteristics of the vertical deflection sys
tem. Refer to Table 1-1 for the characteristics.
Sweep Generation
Sweep Rates 0.1 /j.sec/cm to 5sec/cm in 24 calibrated
(at IX steps. Sweep-rate accuracy is ±2% of the
magnification) indicated rate.
Sweep Any sweep rate can be increased by ex-
Magnification ponding the center portion of the display
horizontally in fixed steps of 2X, 5X, 10X,
20X, 50X, and 100X. Sweep-rate accuracy
is within 5% in the magnified position:, at
effective sweep rates up to lOnsec/cm.
Trigger Source Internal normal, internal plug-in, external,
Selection and line.
Trigger Coupling Dc, ac, and ac low-frequency rejection.
Selection
Trigger Signal Internal (ac): Minimum deflection is 2 mm
Requirements with signals at about 150cps, rising to 1
cm at about 50 cm.
Internal (dc): Minimum deflection is 5 mm
at dc.
Internal (ac low-frequency rejection): Mini
mum deflection is 2 mm with signals at
about 2 kc, rising to 1 cm at about 50 me.
External: Frequency ranges are the same
as internal. Minimum amplitude is 200
mvolts peak-to-peak (ac), 200 m volts
change in dc level (dc), and 200 mvolts
peak-to-peak (ac low-frequency rejection).
A MAXIMUM INPUT OF ± 30 VOLTS
must not be exceeded in the EXTERNAL
trigger position. Minimum trigger level
range is greater than ± 2 volts with the
TRIGGER LEVEL control pushed in and
±20 volts with the control pulled out.
Horizontal Deflection System
The following characteristics apply when the HORIZONTAL
DISPLAY switch is set to the EXT position.
Deflection Factor Variable in fixed steps of .1, 1, and 10
volts/cm. Accuracy is ±5% when VARI
ABLE control is set to CALIBRATED.
