Tektronix 507, Инструкция по эксплуатации

Страница: 11 / 60

MANUAL TRIGGER switch is primarily for photo­
graphing a zero reference line and any or all of the calibrated vertical position lines, to create,
in effect, a parallax-free graticule.
POWER SUPPLIES
Cathode-Ray Tube Accelerating V oltage
An oil-sealed supply of the a-f oscillator type
provides 24 kv (+20 kv and —4 kv) for the ac­
celerating potentials. The —4-kv supply is reg­
ulated to compensate for load changes and line-
voltage changes.
Low-Voltage Supply
A separate power unit provides regulated dc
voltages for the indicator unit of +750, +475,
+225 and —250 volts. The unit also provides
an unregulated voltage of +360 volts for the
oscillator in the high-voltage supply for the crt
circuit.
Power Requirements
600 watts at 117 volts. Voltage range 105-125
or 210-250 volts, 60-cycle, single-phase ac. Two
primary circuit fuses are provided for protection
against sustained over-load conditions.
MISCELLANEOUS
Cathode Ray Tube
A Type T507P cahode-ray tube with PI 1 phos­
phor is furnished with the Type 507 unless an­
other phosphor is specified.
Construction
Contained in two separate units of convenient
size, normally mounted on a Tektronix Type
500A Scope-Mobile. The anodized chassis and
the blue wrinkle-finished cabinets are made of
an aluminum alloy. Photo-etched anodized pan­
els are employed.

Tip jack from heater bus.
Variable resistor controlling brightness of lamps illuminating graticule over
face of cathode-ray tube.
Potentiometer controlling the voltage at the astigmatism anode of the cath­
ode-ray tube. Proper setting of the voltage at this anode, with respect to
the deflection plates, permits the spot to be focused sharply in both dimen­
sions simultaneously.
Potentiometer controlling dc grid voltage of the cathode-ray tube and there­
by the brightness of the trace.
Potentiometer controlling the voltage applied to the focusing anode of the
cathode-ray tube for focusing the trace.
