GENERAL
DESCRIPTION
CATHODE RAY TUBE (CRT)
Rectangular flat faced CRT.
Display area 10 x 8 divisions (each division = 1.0cm)
Phosphor P31
Overall accelerating potential 1.8kV
Z Blanking 15V amplitude, d.c. coupled.
VERTICAL AMPLIFIERS
OPERATING MODES CH2
CH1 and CH2 alternate from lms/div to 0.2us/div.
CH1 and CH2 chopped from 0.2s/div to 2ms/div.
Chop or alternate selected automatically on SECS/DIV switch.
Add and subtract CH1 and CH2 algebraically. (D1011 only).
X-Y (D1011 only) Bandwidth is DC to 1.5MHz (-3db).
Phase error is <3° at 100kHz.
BANDWIDTH (-3db)
DC coupled DC - 10MHz
AC coupled 8Hz - 10MHz
Risetime 35ns (approx)
VERTICAL DEFLECTION
Calibrated (12 steps 1.2.5 sequence) 5mV/div to 20V/div ±5%
Input impedance 1Mohms in parallel with 45pF approx.
Maximum Input Voltage 500V peak a.c. or d.c.
Maximum Scan Amplitude 8 divs (6 divs at 10MHz)
x5 Gain Sensitivity (D1011 only) lmV/div [bandwidth DC to 4MHz (-3db)]
HORIZONTAL DEFLECTION
SWEEP SPEEDS
(19 steps in 1,2,5 sequence)
Normal 0.2s/div to 0.2us/div+5%
x5 Gain Maximum speeds of 40ns/div ±7%
On D1011 only a variable uncalibrated control provides continuous coverage between steps extending the slowest speed to 0.5s/div.
TRIGGER
Fully operational from 10Hz to 15MHz
Normal Level control will select any point on the waveform ± 4 divs about the mean d.c. level of the signal.
Automatic trigger on all repetitive waveforms >0.5 div and with mark space ratio <500: 1. The level control will select any point on the waveform between 10% and 90% (approx) of the peak to peak value.
TV TV field for sweep ranges 0.2s/div to 10us/div and TV line from
5us/div. to 0.2us/div. (Level control inoperative).
Source Internal. CH1 CH2 External
All positive or negative.
Internal Sensitivity 0.5 div
External Sensitivity 0.5V
EXTERNAL X
Bandwidth
DC coupled DC to 1.5MHz (-3db)
AC coupled 10Hz to 1.5MHz (-3db)
Sensitivity 1V/div approx.
Input Impedance 280k ohms in parallel with 30pF approx.
CAL OUTPUT SOCKET
Output Voltage 250mV ±2% peak to peak
Frequency At sweep repetition rate
Wave Shape Vertical step at screen centre
GENERAL
POWER REQUIREMENTS
Mains
