6. Set the time-bases to start the delayed sweep after the
delay time.
7. Set the delaying time-base sweep rate to
100 microseconds per division.
8. Advance the oscilloscope readout and intensity
controls to obtain a usable readout and intensified sweep
display on the CRT.
9. Connect the P6055 probe to the M2 INPUT
connector. The vertical sensitivity readout display should
change from 500 mV to 5 V.
10. Set the P6055 probe Hf Term adjustment for
maximum resistance. (fully counterclockwise.)
11. Connect the probe tip to. a 20 volt DC voltage
source.
12. Adjust the probe Dc Atten adjustment for a voltage
readout display of +20.00 V on the CRT.
13. Remove the probe from the DC voltage source.
14. Connect the oscilloscope delayed sweep + gate to
the 7D12 TRIGGERING EXT IN connector.

15. Set the 7D12 TRIGGERING to EXT and the GATE
toON.
16. Connect the P6055 probe directly to a one kilohertz
square-wave generator.
17. Adjust the square-wave generator to display
approximately 20 volts (4 divisions) of signal on the CRT.
18. Set the delaying time-base sweep rate to
100 nanoseconds per division.
19. Adjust the Delay Time Multiplier control to position
the S1 measurement point 750 nanoseconds after the
square-wave step function begins. See Fig. 3-6.
20. Adjust the P6055 probe Lf Comp (located on the
probe body) for a voltage readout display of 0.00 V.
21. Remove the probe from the square-wave generator.
This concludes the probe adjustment procedure.
