BEFORE OPERATING
INTRODUCTION
The Tektronix 466 and 464 are dual-channel portable
oscilloscopes. The 466 storage system provides storage
for displays with a writing speed up to 3000
divisions/microsecond (in the Fast-Reduced Scan mode).
The 464 storage system does not have the reduced scan
mode and the writing speed is up to 110 divisions/microse-
cond in the Fast mode. The remaining features are
identical. Storage viewtime is greater than 15 seconds at
full-stored display intensity-extending to more than 6
minutes using reduced intensity in the Save mode.
The dual-channel dc-to-100 MHz vertical system
provides calibrated deflection factors from 5 millivolts to 5
volts/division. The sweep trigger circuits are capable of
stable triggering over the full bandwidth capabilities of the
vertical deflection system. The horizontal deflection
system provides calibrated sweep rates from 0.5 second to
0.05 microsecond/division along with delayed sweep
features
for accurate relative-time measurements. A X10
magnifier extends the calibrated sweep rate to 5
nanoseconds/division. The instrument operates over a
wide variation of line voltages and frequencies. Maximum
power consumption is about 100 watts.
The
Tektronix DM44 Digital Multimeter measures 0
ohm to 20 megohms, 0 de volt to 1200 de volts(+ or-), or ,,
(using the temperature probe) -55°C to +150°C. The
measurement is displayed on a 3-1/2 digital display while
the oscilloscope operates normally.
The digital multimeter and oscilloscope combine to
provide a digital readout of the time between any two
points on the oscilloscope display. Both time measure-
ment points are displayed on the crt at the same time. The
1/TIME function can provide direct measurement of
frequency.
SAFETY INFORMATION
The instrument is designed to operate from a single-
phase power source with one of the current-carrying
conductors (the Neutral Conductor) at ground (earth)
potential. Operation from
power sources where both
current-carrying conductors are live with respect to
ground (such as phase-to-phase on a three-wire system)
is
not recommended, since only the Line Conductor has
over-current (fuse) protection within the instrument.
