in both the ON and OFF positions of the
5X MAGNIFIER.
8. Sawtooth Ampl /Sweep Length
Adjustment
With the 5X MAGNIFIER OFF, position the
timing comb until the first time marker is
superimposed on the zero graticule line.
Now adjust the Sweep Length adjustment
until five 100 MICROSEC markers appear to
the right of the tenth graticule line. This will
make a sweep length of 10.5 divisions.
9. Checking Lower Sweep Rates
With the TIME/DIV and Time Marker
Generator set as below check for the proper
time marks per divisions. If the proper number
of Time Markers per division doesn't appear
check for an out of tolerance timing capacitor
or resistor.
1l. Check remaining High
Frequency Ranges
Triggers from the Type 180 can be used when
checking the sweep rates above although the
signal from the VERT SIG OUT of the 536
will provide stable triggering.

10. High Frequency Timing
The following adjustments may have to be
repeated several times due to interaction
between the adjustments.
5X MAGNIFIER should be on for this check.
tt The external trigger for the T should be 10 MICROSEC triggers
from the Type 180 for these two steps.
