Performance Check/Calibration-Type 453/R453
Five-division display with variable control at CAL
Must be reduced to at least two divisions when
fully counterclockwise
Fig.
5-14. Typical CRT display showing adequate Channel 1 and 2
VARIABLE control range (double exposure).
16. Check Channel 1 and 2 Variable Volts/
Division Range
.a. Set the stanard amplitude calibrator for a 0.1-volt
square-wave output.
b. Change the following control settings:
VOLTS/DIV
(CH 1 and 2) 20 mV
Input Coupling
(CH 1 and 2)
MODE
AC
CH 1
c. CHECK-Turn the Channel 1 VARIABLE VOL TS/DIV
control fully counterclockwise. Display should be reduced to
two divisions or less (see Fig. 5-14). Channel 1 UNCAL light
must be on when Channel 1 VARI ABLE control is not in CAL
position.
d. Set the MODE switch to CH 2.
e. CHECK-Turn the Channel 2 VARIABLE VOLTS/DIV
control fully counterclockwise. Display should be reduced to
two divisions or less (see Fig. 5-14). Channel 2 UNCAL light
must be on when Channel 2 VARIABLE control is not in CAL
position.
f. Disconnect the cable from the Channel 2 INPUT con-
nector.
17. Check Channel 1 and 2 Cascaded
Deflection Factor
a. Connect the CH 1 OUT connector to the Channel 2
INPUT connector with the 18-inch 50-ohm BNC cable.
b. Change the following control settings:
VOLTS/DIV
(CH 1 and 2)
