NOTE
In this procedure, pressing up and releasing TRIGGER
COUPLING switch stores current calibration parameter being
set and increments routine to next step (except where
otherwise noted).
NOTE
Throughout this paragraph the INTENSITY and POSITION
controls may be adjusted as necessary for proper viewing of
displayed signal.
(3) Connect multimeter LO to chassis ground and HI to TI CALIBRATOR output
(front panel).
(4) Set multimeter to measure dc volts.
(5) Push up and release upper TRIGGER COUPLING switch.
The display
readout will indicate ADJ Δ, (step) 1, 100 μs and 1 μs.
(6) Multimeter indication will be 0 mV l mV.
(7) Set oscilloscope calibrator for a CHAN 1, MARKER mode output of .1 ms/div.
(8) Set VOLTS/DIV switch as needed for a convenient signal amplitude.
(9) Adjust TRACE SEP control as needed to separate the A and B sweeps.
(10) Adjust CH 1 POSITION control as needed to view both A and B sweeps.
(11) Adjust HORIZONTAL POSITION control to start trace at the left graticule line.
(12) Adjust ΔREF OR DLY POS and Δ controls to align both intensified zones with
the 6th time marker near graticule center and to superimpose the delayed B sweep time markers.
(13) Push up and release TRIGGER COUPLING switch. Check multimeter
indicates between 398 mV and 402 mV and TI readout indicates ADJ Δ (step) 2, 100 μs, 1 μs.
(14) Disconnect multimeter from TI and adjust ΔREF OR DLY POS control to
intensify 2d time marker.
(15) Adjust Δ control to intensify 10th time marker and superimpose delayed B sweep
time markers within .2 division.
(16) Push up and release TRIGGER COUPLING switch.
(17) Display readout will indicate ADJ Δ, (step) 3, 300 μs, 1 μs.
(18) Adjust ΔREF OR DLY POS control to intensify 4th time marker and Δ control to
intensify 28th time marker and superimpose delayed B sweep markers within 1.2 division.
(19) Push up and release TRIGGER COUPLING switch.
NOTE
If adjustments are made in (18) above, display readout will
indicate ADJ Δ (step) 2, 200 μs, 1 μs. Repeat (14) through (19)
above until no adjustments are made in (18) above.
