Appendix C: Performance Verification
Step 4: Check Delay Time Differential Accuracy
a. Use the Horizontal
POSITION control to align the start of the A
Sweep with the
lSt vertical graticule line.
b. Set the
B DELAY TIME POSITION control fully counterclockwise.
c. CHECK
- lntensified portion of the trace starts within 0.5 division of
the start of the sweep.
d. Rotate the
B DELAY TlME POSITION control fully clockwise.
e. CHECK
- lntensified portion of the trace is past the 1 1 th vertical
graticule line.
f.
Set the
A and B SECIDIV switch to 0.5 ps.
g. Repeat parts a through e. When performing step c, check that the
trace starts with 1.1 division instead of 0.5 division.
h. Set:
CH 1 AC-GND-DC DC
B SECIDIV 0.05 ps
B DELAY TIME POSITION
Fully counterclockwise
i. Select 0.5 us time markers from the time-mark generator.
j.
Rotate the B DELAY TlME POSITION control so that the top of the
2nd time marker on the B Sweep is aligned with a selected reference
vertical line. Record the
DLY= readout for part use with part I.
k. Rotate the
B DELAY TlME POSITION control fully clockwise until
the top of the
10th time marker on the B Sweep is aligned with the
same selected reference vertical line as in part k. Record the
DLY=
readout for part use with part I.
I. CHECK
- Delay time readout is within the limits given in Table A-12
(Delay Readout Limits column) by subtracting the delay time reading
in part
j from part k.
m. Repeat parts j through I for the remaining B SECIDIV and time-mark
generator settings given in Table A-1
2, check the eight division delay
time accuracy for each
A SECIDIV switch setting given in column 1
of the table.
