12. Calibrator
a. Performance Check
(1) Press corresponding pushbuttons for indications as listed in (a) through (c) below:
(a) VERTICAL MODE CH 1 on and VERTICAL MODE CH 2, CH 3 and CH 4 off.
(b) CH 1 input coupling to 1 MΩ.
(2) Set CH 1 and CH 2 VOLTS/DIV switches to 50 mV, and VAR control fully cw
to detent.
(3) Set A SWP and B SWP SEC/DIV switch to 50 s (knobs locked) and adjust
SEC/DIV VAR control fully cw to detent.
(4) Connect CH 1 to TI CALIBRATOR output terminal.
(5) Set CH1 VAR control for a full-scale (8 division) vertical display.
NOTE
If VAR control will not display full scale, set VOLTS/DIV
switch for 20 mV.
(6) Disconnect TI calibrator from CH 1.
(7) Connect oscilloscope calibrator SOURCE/MEASURE CHAN 1 to TI CH 1.
(8) Set oscilloscope calibrator for a CHAN 1, VOLTAGE mode output of 400 mV at
10 kHz frequency.
(9) Rotate oscilloscope calibrator knob below EDIT FIELD pushbutton to adjust
amplitude for 8 divisions of deflection on TI. If oscilloscope calibrator err display is not
≤ 1%, perform b below.
13. Parametric Measurements
a. Performance Check
(1) Press VERTICAL MODE CH1 pushbutton to on and VERTICAL MODE CH
2, 3 and 4 pushbuttons to off.
(2) Press CH1 input coupling pushbutton to 50 Ω DC.
