(15) Press DISABLE pushbutton (model 9211 output module) to off (red light lit).
(16) Disconnect cable from TI 9211 module OUTPUT.
(17) Connect cable to TI 9215 module OUTPUT.
(18) Press TI pushbuttons as listed in (a) through (h) below:
(a) CHANNEL B.
(b) Vhigh and enter 5 from data keyboard and press ENTER/Hz.
(c) Vlow and enter 0 from the data keyboard and press ENTER/Hz.
(d) Lead and enter 5 from data keyboard and press n/GHz.
(e) Trail and enter 5 from data keyboard and press n/GHz.

(g) Wid and enter 10 from data keyboard and press n/GHz.
(h) Press DISABLE pushbutton (model 9215 output module) to on (red
light extinguished).
(19) Setup digitizing oscilloscope to display the pulse train.
(20) Setup digitizing oscilloscope to perform a T measurement by placing V marker
1, V marker 2, Start Marker and Stop Marker at the same point of the leading edge of the
left most pulse that is displayed on the crt.
(21) Press TI pushbuttons as listed in (a) and (b) below:
(a) CHANNEL B.
(b) Delay and enter 10 from data keyboard and press n/GHz.
(22) Set digitizing oscilloscope Stop marker on the leading edge of the displayed pulse
where the V markers intersect the pulse.
(23) Verify that the digitizing oscilloscope T indication is within the limits listed in
table 17 for the Delay setting.
(24) Set TI to the next Per and Wid settings listed in table 17.
(25) On the digitizing oscilloscope turn off the V markers and the Start and Stop
markers.
(26) Repeat (22) and (23) above.
