Tektronix 2247A

Performance Check Procedure
20.
Set the leveled sine-wave output amplitude for an eight-division
display.
Set the Vertical MODE to ADD (CH 1 off).
CHECK —the signal is less than 0.8 division In amplitude.
Disconnect the test setup.
Channel Isolation
Set:
Vertical MODE CH 1 and CH 2
(ADD off)
CH 2 INVERT Off
CH 1, CH 2, CH 3, and CH 4
VOLTS/DIV 0.1Vv
Trigger SOURCE CH1
Connect the leveled sine-wave generator (SG 503) output to the CH 1
Input via a 50 © precision BNC coaxial cable and a 50 1 BNC
termination,
Set the leveled sine-wave generator (SG 503) output for a five-division
signal display amplitude at 100 MHz.
Set CH 2, CH 3, and CH 4 Vertical MODE On (CH 1 off).
CHECK—dlsplay amplitude is 0.1 division or less, excluding trace
width, on the CH 2, CH 3, and CH 4 traces.
Move sine-wave generator signal to the CH 2 Input.
Set:
Vertical MODE CH 1, CH 3, and
CH 4 (CH 2 off)
Trigger SOURCE CH 2
CHECK—display amplitude Is 0.1 division or less, excluding trace
width, on the CH 1, CH 3, and CH 4 traces.
Move sine-wave generator signal to the CH 3 Input.
