Performance Check Procedure
Set function generator output for 1 kHz sine-wave signal of five
divisions peak-to-peak with maximum positive dc offset.
Position the bottom of the signal to the center horizontal graticule line.
Set CH 1 Input COUPLING to AC.
CHECK—display Is roughly centered about the center horizontal
graticule line.
Move the test signal to the CH 2 input.
Set CH 2 Vertical MODE to on (CH 1 off).
Repeat the procedure for CH 2.
Disconnect the test signal from the 2247A.
CH 1 and CH 2 VOLTS/DIV Trace Shift
Set:
CH 1 and CH 2
Vertical MODE On
CH 1 and CH 2
VOLTS/DIV 2mv
CH 1 and CH 2
Input COUPLING GND
Set Vertical MODE to CH 1 (CH 2 off).
Position trace to center horizontal graticule line.
Switch CH 1 VOLTS/DIV through all positions from 2 mV to 5 V.
CHECK—trace shift does not exceed 0.2 division between steps.
Set Vertical MODE to CH 2 (CH 1 off).
Position CH 2 trace to the center horizontal graticule line.
Switch CH 2 VOLTS/DIV through all positions from 2 mV to 5 V.
CHECK—trace shift does not exceed 0.2 division between steps.
