ON pushbutton and adjust CURSORS as
(7) Press f (function) and CURSORS
shown in figure 8.
(8) Press AVE N pushbutton. CURSORS readout will indicate between 49.6 and
50.4 mW; if not, adjust CH 1 GAIN R344 (fig. 2) for V=50.0 mV (R).
Figure 8. Typical CURSORS
display.
(9) Set CH 1 VOLTS/DIV switch to 20 mV, press AVE N, and adjust CH 1
POSITION to align trace with center graticule lines.
(10) Adjust CH 1 POSITION control to move the two division display over the entire
graticule area. The CURSORS readout will not vary more than 2.4 mV.
(11) Press MENU/TEST and MEMORY DISPLAY 4, 5, 6 and MENU/TEST pushbuttons.
(12) Position controls as listed in (a) through (d) below:
Press AQR MODE CH 2 2 pushbutton.
(a)
Set CH 2 VOLTS/DIV switch to 10 mV.
(b)
Press CH 2 GND pushbutton.
(c)
Set TIME/DIV switch to 500 s.
(d)
(13) Adjust CH 2 POSITION control to align trace with the center graticule line.
(14) Connect a shorting cable between TP1230 and TP520 TP GND (fig. 4). TI VZR
display will indicate between -0.2 and +0.2; if not, adjust CH 2 CENTER R510 (fig. 3) to
align trace with center graticule line (R).
(15) Remove shorting cable from TP1230 and TP520 TP GND (fig. 4).
(16) Press CH 2 AC pushbutton and set VOLTS/DIV to 20 mV.
(17) Connect oscilloscope calibrator SOURCE/MEASURE CHAN 1 output to CH 2
input and adjust oscilloscope calibrator frequency for 1 kHz and amplitude for 50 mV.
(18) Press AVE N pushbutton. CURSORS readout will indicate between 49.6 and
50.4 mW; if not, adjust CH 2 GAIN R377 (fig. 3) for V=50.0mV (R).
