(8) Press HORIZ DISPLAY push-button B DLY'D to on (in). Adjust DELAY
TIME POSITION dial to align start of signal with start of sweep trace. DELAY TIME
POSITION dial will indicate 1.98 to 2.02.
(9) Repeat technique of (6) through (8) above for each time marker listed in table 7
below. DELAY TIME POSITION dial indications will be within specified limits.

a. Performance Check
(1) Position TI controls as listed in (a) through (e) below:
HORIZ DISPLAY pushbutton A to on (in).
(a)
VERT MODE BW pushbutton to full bandwidth.
(b)
VERT MODE pushbutton CH 2 to on (in).
(c)
CH 1 and CH 2 VOLTS/DIV switches to 5 m.
(d)
A and B TIME/DIV switches to .1 μs.
(e)
(2) Connect oscilloscope calibrator to CH 2 input through X10 attenuator and 50
Ω termination.
(3) Set oscilloscope calibrator for EDGE mode, 1MHz.
(4) Adjust oscilloscope calibrator for 6 divisions (5 divisions for Tektronix, Type 466
SN B200000 and above) of vertical deflection on TI. If square wave has displayed
aberrations of more than +1 or -1 minor division or 1 minor division p-p, perform: b (1)
below for Tektronix, Type 466 with SN below B200000; b (2) below for Tektronix, Type 466
with SN B200000 and above; b (3) below for Tektronix, Type 464.
(5) Remove connection from CH 2 input and connect to CH 1 input and press
VERT MODE pushbutton CH 1 to on (in).
(6) Repeat technique of (4) above for CH 2. If square wave has displayed
aberrations of more than +1 or -1 minor division or 1 minor division p-p, perform: b (4)
below for Tektronix, Type 466 with SN below B200000; b (5) below for Tektronix, Type 466
with SN B200000 and above; b (6) below for Tektronix, Type 464.
(7) Disconnect oscilloscope calibrator from TI and set A and B TIME/DIV switches
to .2 ms and press VERT MODE pushbutton CH 1 to on (in).
(8) Connect oscilloscope calibrator to CH 1 input through X 10 attenuator, 50 Ω
termination, and 5 - 80 pF standardizer.
