Information
The Tektronix Type 453 Oscilloscope is a transistorized
portable Oscilloscope designed to operate in a wide range
of environmental conditions. The light weight of the Type
453 allows it to be easily transported, while providing the
performance necessary for accurate high-frequency measurements.
The dual-channel DC-to-50 MHz vertical system
provides calibrated deflection factors from 5 millivolts to
10 volts/division. Channels 1 and 2 can be cascaded using
an external cable to provide a one millivolt minimum defect-
ion factor (both VOLTS/DIV switches set to 5 mV).
The trigger circuits provide stable triggering over the full
range of vertical frequency response. Separate trigger controls
are provided to select the desired triggering for the A
and B sweeps. One of three sweep modes can be selected
for the A sweep; automatic, normal or single sweep. The
horizontal sweep provides a maximum sweep rate of 0.1
microsecond/division (10 nanosecond/division using 10X
magnifier) along with a delayed sweep feature for accurate
relative-time measurements. Accurate X-Y measurements
can be made with Channel 2 providing the vertical deflection,
and Channel 1 providing the horizontal [deflection. (TRIGGER
switch set to CH 1 ONLY, HORIZ DISPLAY switch set to EXT
HORIZ). The regulated DC power supplies maintain constant
output over a wide variation of line voltages and frequencies.
Total power consumption of the instrument is
approximately 90 watts.
Information given in this instruction manual applies to the
Type R453 also unless otherwise noted. The Type R453 is
electrically identical to the Type 453 but is mechanically
adapted for mounting in a standard 19-inch rack.
