a. Performance Check
(1) Press and hold CH 1 and CH 2 input coupling pushbuttons to PUSH BOTH
BALANCE position until display readout indicates DC BALANCE IN PROGRESS.
(2) When signal and readout displays automatically return to normal, connect
oscilloscope calibrator SOURCE/MEASURE CHAN 1 through CHAN 4 to TI CH 1
through CH 4 inputs respectively.
(3) Press corresponding pushbuttons for indications as listed in (a) through (e) below:
(a) VERTICAL MODE CH 1 on, and VERTICAL MODE CH 2, CH 3, and
CH 4 off.
(b) 20 MHz BW LIMIT to on.
(c) CH 1 and CH 2 input coupling to 1 0: DC.
(d) TRIGGER coupling to DC.
(e) TRIGGER SOURCE to VERT CH 1.
(4) Set CH 1 VOLTS/DIV switch to 2 mV and A SWP SEC/DIV switch to 1 ms.
(5) Set oscilloscope calibrator for a CHAN 1, VOLTAGE mode output of 10 mV at 1
