Tektronix 475 User Manual

Specification—475
LF REJ Coupled: 0.3 division internal or 100 millivolts
external from 50 kilohertz to 40 megahertz, increasing to
1.5 divisions internal or 500 millivolts external at 200
megahertz. Blocks DC and attenuates all signals below
about 50 kilohertz.
HF REJ Coupled: 0.3 division internal or 100 millivolts
external from 60 hertz to 50 kilohertz. Blocks DC and
attenuates all signals below about 60 hertz and above about
50 kilohertz.
Trigger Jitter
0.2 nanosecond or less at 200 megahertz at 1
nanosecond/division (X I0 MAG on).
External Trigger Input
Maximum input voltage is 250 V DC + peak AC or
250 V P-P AC (1 kilohertz or less). Input impedance is 1
megohm within 10%, paralleled by approximately 20
picofarads.
LEVEL Control Range
EXT: At least + and —2 volts, 4 volts peak to peak.
EXT -HO: At least + and —20 volts, 40 volts peak to
peak.

Variable Time/Division Control Range
Provides continuously variable (uncalibrated) sweep
rates between the calibrated settings of the TIM E/D IV
switch. Extends the slowest A sweep rate to at least 1.25
seconds/division.
Exclude the LF REJ coupling mode.
Trigger View Deflection Factor
Approximately 50 millivolts/division.
A Trigger Holdoff
Increases A sweep holdoff time to at least nine times the
TIM E /D IV switch setting.
HORIZONTAL DEFLECTION SYSTEM
Calibrated Sweep Range
A Sweep or B DLYD Sweep: from 0.5 second/division
to 0.01 microsecond/division in 24 steps in a 1-2-5
sequence. X I0 MAG extends maximum sweep rate to 1
nanosecond/division.
A Delaying Sweep: from 0.5 second/division to 0.05
microsecond/division in 22 steps in a 1-2-5 sequence.
