a. Test equipment, with connections made at comple
tion of step 22c, is shown in Fig. 7-29.
b. Check that the controls are set as given in the list
that precedes step 22.
c. Apply the 100-kHz fast-rise signal from the -f Output
connector on the Type 106 through a 5-ns cable and 50-
ohm in-line termination to the Type 1A1 Channel 1 INPUT
connector (see Fig. 7-29).
d. Set the Type 106 -f-Transition Amplitude control to
obtain a 4-cm amplitude display. Set the Symmetry control
to obtain a symmetrical waveform and, if necessary, ad
just the Multiplier control to obtain the 100 kHz output rep
etition rate. Use the Type 1A1 Channel I position control
to center the display.
