Check Deflection Accuracy; Check Trace Shift - Tektronix 2212 User Manual

Performance Tests
C-10
Procedure Steps
Step 1. Check Deflection Accuracy
a. Connect a 10 mV standard-amplitude signal from
the calibration generator via a 50
Q
BNC coaxial cable
to the
CH 1 OR X input connector.
b. CHECK - Deflection accuracy is within the limits
given in
Table C-2 for each CH 1 VOL TS/DIV switch setting
and corresponding standard-amplitude signal.
Step 2. Check Trace Shift
a. Set CH 1 VOLTS/DIV switch to 2 mV/division.
b. Rotate the VOLTS/DIV switch through the range.
c. CHECK - The trace shift should be $ 1.0 division.
d. Set the VAR to the minumum sensitivity, and rotate
the VOLTS/DIV switch through the range.
e. CHECK - The trace shift should be$ 1.0 division.
f. Move the cable from the CH 1 OR X input connec-
tor to the CH 2 ORY input connector. Toggle the
MODE
switch to CH 2.
g. Repeat part b through fusing the CH 2 controls.
h. Push the CH 2 INVert switch to the INV position.
j. CHECK - The trace shift should be$ 1.5 division.
