Tektronix 545A Instruction Manual page 6

Characteristics — Type 545A
Accelerating potential — 10,000 volts.
Usable viewing area:
Type 545A Oscilloscope — 4 by 10 centimeters.
Graticule
Illumination — variable edge lighting.
Type 545A graticule markings — marked in 4 vertical and 10
horizontal 1 -centimeter divisions with 2-millimeter markings
on the centerlines.
Amplitude Calibrator
Waveform — square-waves at approximately 1,000 cycles.
Output voltage — 0.2 millivolts peak-to-peak to 100 volts
peak-to-peak in 18 steps.
Accuracy — peak-to-peak amplitudes of square-waves within
3% of indicated voltage.
Power Supplies
Electronically regulated for stable operation with widely
varying line voltages and loads.

Fig. 1-1. Output waveforms available at the Oscilloscope front panel.
Line voltage requirements — 105 to 125 volts, or 210 to 250
volts.
Power — approximately 500 watts with a Type CA Plug-In
Unit installed.
Line frequency — 50 to 60 cycles.
Output Waveforms Available
Delayed trigger pulse — approximately 5 volts in amplitude,
occurring at the end of the delay period.
Positive Gate B — approximately 20 volts peak-to-peak with
same duration as sweep B.
Positive Gate A — approximately 20 volts peak-to-peak with
same duration as sweep A.
awtooth A — sweep A sawtooth waveform, approximately
150 volts peak.
Vertical signal output — output from vertical deflection sys ­
tem. Approximately 1.5 volts peak-to-peak per centimeter
of vertical deflection.
Ventilation
Forced filtered air. Thermal
power in the event of overheating.
