PERFORMANCE VERIFICATION
PROCEDURE
Settings/procodure/requ
Irements:
A Apply a
50
MHz $lne wave
signal of 1 00 mV peak-lo-peak
to channel A. Use a 500 termination.
B Switch on the
ScopeMeter and press the SCOPE key to
get into SCOPE mode. Now press me
ALfTO SET key.
Check that the display Is stable and well triggered.
Minimal 2 and maximal 20
signal periods
must be displayed, over 8 divisions.
The signal amplitude must be approximately
5
divisions.
The NOTRIG indication
on
the display
must not flash.
C Repeat settings/p rocedure for ch an
n el
B.
2. Vertical
dynamic range and position range
(move control)
All models
•••
This test checks
the vertical dynamic range, together with the position
range (move control). A certain
overdrive of
the ScopeMeter must be allowed.
Test
equipment:
Tektronix SG 503 Constant Amplitude Sine wave Generator
Test setup:
ScoMMeier
Settings/procedu
re/requirements for channel A:
Vertical dynamic range
check:
A Switch on the
ScopeMeter and press the SCOPE key to get Into
SCOPE mode.
6 Apply a 50 kHz sine wave signal of
950 mV peak-to-peak to channel A.
Use a 50Q termination.
C Press the AUTO SET key.
Set
channel
A to 1 00 mV/dIv. and set the tlmebas©
speed to lOps/div.
D Use the vertical MOVE
key
to shift
the bottom of the sine wave vertically over the
screen in the
lower division. Shin the top of the sine
wave in the upper division. Verify that the
top and bottom
of the sine wave signal
of 9.5
divisions
can be displayed distortion
free.
E Apply a
50 MHz
sine
wave signal of approximately 500 mV peak-
to- peak
(4
divisions on the
screen) to channel
A. Use a 50Q termination.
F Set the time base
speed to 10 ns/dtv.
G Now a sine wave with an amplitude
of 4 divisions must be displa/ed distortion Iree.
Move control
check:
A Adjust the signal amplitude to 6 divisions on the screen.
B Check
that the trace can be moved over 4 divisions
up
(
+ 4 dI
v.)
and over4 dvisions down (-
4 d
iv. )
.
Settlngs/procedure/requlrements
for channel 6:
Repeat the total procedure
for
channel
A.
