Tektronix 465 Oscilloscopes Specifications

VERTICAL DEFLECTION (2 IDENTICAL CHANNELS)
Bandwidth* and Rise Time (at all deflection factors from 50 Ω Terminated source)		-15°C to +40°C			+40°C to +55°C
		Dc to 100 MHz, 3.5 ns			85 MHz, 4.1 ns
*Measured at -3 dB, Bandwidth may be limited to approx 20 MHz by bandwidth limit switch.
Lower -3 dB point, ac coupling 1X probe: 10 Hz or less. 10X probe: 1 Hz or less.
Deflection Factor at BW		5 mV/div to 5 V/di
1-2-5 sequence, accurate ± 3%. Uncalibrated, continuously variable between steps and to at least 12.5 V/div (465/475) to at least 25 V/div (475A). In cascade mode sensitivity is approx 1 mV/div ; approx 400 µV/div (475); and approx 2.5 mV/div (475A). Cascaded bandwidth is at least 50 MHz when signal out is terminated in 50 Ω.
Display Modes		Ch 1; Ch 2 (normal and inverted), alternate, chopped (465-approx 250 kHz rate, 475/475A-approx 1 MHz rate), added; X-Y (Ch 1-X, Ch 2-Y)
CMRR		Common-mode rejection ratio at least 20 dB at 20 MHz (50 MHz for 475/475A) for common-mode signals of 6 div or less
Automatic Scale Factor		Probe tip deflection factors for 1X or 10X coded probes are automatically indicated by two readout lights behind the knob skirts. All lights are off when the channel is not displayed. Ground reference display selectable at probe (when dc coupled).
Input R and C		1 MΩ ± 2% paralleled by approx 20 pF.
Max Input Voltage		Dc Coupled			250 V (dc + peak ac) 500 V (p-p ac at 1 kHz or less)
		Ac Coupled			500 V (dc + peak ac) 500 V (p-p ac at 1 kHz or less)
Delay Line		Permits viewing leading edge of displayed waveform
Probe Power (475/475A only)		Connectors provide correct voltages for two optional P6201 FET Probes
HORIZONTAL DEFLECTION
Time Base A		0.05 µs/div to 0.5 s/div (1-2-5 sequence). X10 mag extends max sweep rate to 5 ns/div.
Time Base B		0.05 µs/div to 50 ms/div (1-2-5 sequence). X10 mag extends max sweep rate to 5 ns/div.
Variable Time Control		Time Base A provides continuously variable uncalibrated sweep rates between steps and to at least 1.25 s/div. Warning light indicates uncalibrated setting.
Time Base A and B Accuracy, full 10 cm		Unmagnified	+20°C to +30°C				-15°C to +55°C
			± 2%				± 3%
		Magnified	± 3%				± 4%
Horizontal Display Modes		A, mixed sweep, A intensified, B delayed. B ends A for increased intensity in the delayed mode.
Calibrated Mixed Sweep		Displays A sweep for period determined by delay-time position control, then displays B sweep for remainder of horizontal sweep.
CALIBRATED SWEEP DELAY
Delay Time Range		0.2 to X10 delay time/div settings of 200/ns to 0.5 s (minimum delay time is 200 ns).
Differential Time Measurement Accuracy		Delay Time Setting				+15°C to 35°C
		Over one or more major dial divisions				± 1%
		Less than one major dial division				± 0.01 major dial division
Jitter		1 part or less in 50,000 (0.002%) of 10X the A sweep time/div setting. 1 part in 20,000 when operating from 50 Hz line.
TRIGGERING A AND B
A Trigger Modes		Normal (sweep runs when triggered). Automatic (sweep free-runs in the absence of a triggering signal and for signals below 30 Hz). Single sweep (sweep runs one time on the first triggering event after the reset selector is pressed). Lights indicate when sweep is triggered and when single sweep is ready.
A Trigger Holdoff		Adjustable control permits a stable presentation of repetitive complex waveforms.
B Trigger Modes		B runs after delay time (starts automatically at the end of delay time) and B triggerable after delay time (runs when triggered). The B (delayed) sweep runs once, in each of these modes, following the A sweep delay time.
Time Base A and B Sensitivity and Coupling
		To 25 MHz	At 100 MHz
DC	Internal	0.3 div deflection	1.5 div deflection
	External	50 mV	150 mV
	External +10	500 mV	1.5 V
Ac		Requirements increase below 60 Hz
Ac Lf Reject		Requirements increase below 50 kHz
Ac Hf Reject		Requirements increase below 60 Hz and above 50 kHz
465 Jitter		0.5 ns or less at 100 MHz and 5 ns/div
A Trigger View		A spring-loaded pushbutton overrides other vertical controls and displays the external signal used for A sweep triggering. This provides quick verification of the signal and time comparison between a vertical signal and their trigger signal.
Level and Slope		Internal, permits selection of triggering at any point on the positive or negative slope of the displayed waveform. Level adjustment through at least ± 2 V in external, through at least ± 20 V in external divided by 10.
A Sources		Norm, Ch 1, Ch 2, line, external, and external divided by 10
B Sources		Starts after delay, norm, Ch 1, Ch 2, and external
External Inputs		R and C approx 1 MΩ paralleled by approx 20 pF. 250 V (dc + peak ac) max input.
X-Y OPERATION
Full-sensitivity X-Y (Ch1 Horiz, Ch2 Vert)		5 mV/div to 5 V/div, accurate ± 4%. Bandwidth is dc to at least 4 MHz. Phase difference between amplifiers is 3° or less from dc to 50 kHz.
DISPLAY
CRT		8 X 10 cm display. Horizontal and vertical centerlines further marked in 0.2 cm increments. P31 phosphor standard; P11 option. 18 kV accelerating potential.
Graticule		internal, nonparallax; variable edge lighting; markings for measurement of rise time
Beam Finder		Compresses trace to within graticule area for ease in determining the location of an offscreen signal. A pre-set intensity level provides a constant brightness.
Z-Axis Input		Dc coupled, positive-going signal decreases intensity; 5 V p-p signal causes noticeable modulation at normal intensity; dc to 50 MHz.
