Specification— Type 3 2 3
VERTICAL DEFLECTION SYSTEM (cont)
Characteristic Performance Requirement O perational Inform ation
Bandwidth with Four-Division
Reference
Upper —3 dB Point, AC (capaci­
tive) and DC (direct) Coupled,
with Equivalent Risetime (with
or without P6049 Probe)
X I gain
Four megahertz or greater, and 90 nano­
seconds or less.
VARIABLE VOLTS/DIV control set to CAL.
Risetime calculated from bandwidth meas­
urement using the formula:
360
tr BW
Where:
tr = Risefime in nanoseconds.
BW = Bandwidth in megahertz.
XTO gain 2.75 megahertz or greater, and 130 nano­
seconds or less.
Lower —3 dB Point, AC (capaci­
tive) Coupled ( X I or X 10
gain)
Without probe
Two hertz or less.
VARIABLE VOLTS/DIV control set to CAL.
With P6049 Probe
0.2 hertz or less.
Step Response
Aberrations at .01 VOLTS/DIV Peak aberrations not to exceed + 2 % or
—2%; total peak-to-peak aberrations not
to exceed 3% (—15°C to +55°C).
VARIABLE VOLTS/DIV control set to CAL
Aberrations at all other VOLTS/
DIV switch positions
0° C to + 5 5 ° C
Peak aberrations not to exceed + 3 % or
—3%; total peak-to-peak aberrations not
to exceed 3%.
—15°C to 0°C
Peak aberrations not to exceed + 4 % or
—4%; total peak-to-peak aberrations not
to exceed 4%.
Positioning effect on aberrations
Negligible with signal on screen.
Probe effect on aberrations Negligible.
Overload Recovery
0° C to + 4 0 ° C
One microsecond, or less, to stabilize after
a signal change at the VERT INPUT con­
nector equivalent to + 3 0 or —30 divisions
of deflection.
—15° C to + 5 5 ° C Two microseconds, or less, to stabilize after
a signal change at the VERT INPUT con­
nector equivalent to + 30 or —30 divisions
of deflection.
Displayed Noise at 0.001
