a. Performance Check
(1) Connect oscillator (A4) to TI EXT HOR input, using cable (B4).
(2) Set both TI SOURCE switches to EXT.
(3) Adjust oscillator frequency for 50 kHz and amplitude for 6 divisions of deflection
on crt.
(4) Adjust oscillator frequency until crt displays 4.25 divisions of deflection.
If
oscillator does not indicate 5 MHz or greater, perform b below.
