Tektronix 2467B Service Manual

f. Rotate the A REF OR DLY POS control to center the
intensified zone on one of the time markers near graticule
center.
g. Set the B SEC/DIV to 50 ns (knob out).
h. Rotate the TRACE SEP control CCW to separate
the A and B sweep displays.
i. CHECK—The B sweep is displayed with the A
sweep.
j. Push the SEC/DIV knob in.
k. CHECK—Only the B sweep is displayed.
2. Check A and B Timing, A Cursor Accuracies,
and A Cursor Range.
a. Set:
A SEC/DIV 5 ns (knob in)
TRACE SEP Fully CW
At On (press and release
for At display)
b. Select 5 ns time markers from the Time-Mark Gen-
erator and adjust the TRIGGER LEVEL control for a stable
display.
c. Use the Horizontal POSITION control to align the
2nd time marker with the 2nd vertical graticule line (2nd
from the left edge of the display).
Performance Check—2465B/2467B Service
NOTE
The 2 ns and the 5 ns time markers are sinusoidal.
Use either the rising or falling zero-crossings as
alignment points.
d. Align the A REF OR DLY POS cursor with the 2nd
time marker and align the A cursor with the 10th time
marker.
e. CHECK—The A Sweep timing and cursor readout
accuracies are within the limits given in Tables 4-7
and 4-8.
NOTE
If the 2nd and 10th time markers are within 0.06
division of the 2nd and 10th vertical graticule lines
for unmagnified sweeps and within 0.1 division for
magnified sweeps, the sweep timing accuracy is con-
servatively within limits. When the timing accuracy is
checked at each sweep speed, note any SEC/DIV
setting at which the timing error exceeds the 0.06-
division limit. Check these sweep speeds against the
major-division time-interval limits given in Table 4-8.
NOTE
For SEC/DIV settings of 5 ns and 10 ns, the time-
marker period is greater than 1 division when the
sweep is magnified. At 500 ps per division (SEC/DIV
setting of 5 ns with X10 MAG), input the signal
through a dual input coupler to CH 1 and CH 2.
Select CH 1, CH 2, and CH 2 INVERT. Set the CH 1
and CH 2 VOLTS/DIV settings for a 6 division signal.
Center the waveforms. Check for 2 cycles between
the 2nd and 10th vertical graticule lines (within 0.1
division) at the intersections of the waveforms. For
1 ns per division, check for 4 cycles between the 2nd
and 10th vertical graticule lines (0.1 division).
f. Repeat parts c, d, and e for each A SEC/DIV-time
marker combination given in Table 4-7 for both
unmagnified and magnified sweeps.
