EXAMPLE: The apparent magnification of a display
with an A TIME/DIV switch setting of .1 ms and a B
TIME/DIV switch setting of 1 µs is:
Apparent
Magnification _ A TIME/DIV setting
(Delayed - B
TIME/DIV setting
Sweep)
Substituting the given values:
Apparent
Magnification
1 x 10-
4
1 x 10-6
The apparent magnification is 100 times.
Triggered Delayed Sweep Magnification
The delayed sweep magnification method just describ-
ed may produce too much jitter at high apparent
magnification ranges. Operating the B Sweep in a
triggered mode provides a more stable display since the
delayed
display is triggered at the same point each time.
1. Set up the display as given in steps 1 through 6
under "Magnified Sweep Starts After Delay."
2. Set the B Trigger SOURCE switch to the same
position as the A Trigger SOURCE switch.
3. Adjust the B LEVEL control so the intensified zone
on the trace is stable. (If an intensified zone cannot be
obtained, see step 4.)
4. Inability to intensify the desired portion indicates
that the signal does not meet the triggering requirements.
If
the condition cannot be remedied with the B Triggering
controls or by increasing the display amplitude (lower
VOL TS/DIV setting), trigger B Sweep externally.
5. When the correct portion is intensified, set the
HORIZ DISPLAY switch to B DLY'D. Slight readjustment
of the B LEVEL control may be necessary for a stable
display.
6. Measurements are made and magnification factors
are calculated as in the STARTS AFTER DELAY mode
previously given.
