Tektronix 2247A

Performance Check Procedure
e. CHECK—the displayed signal amplitude Is 4.2 divisions or more as the
frequency Is Increased to 100 MHz.
f. Repeat the frequency setup and CHECK procedure for VOLTS/DIV
settings of 50 mV and 0.5 V.
g. Move the test signal to the CH 2 Input.
h, Set:
Vertical MODE CH 2 (CH 1 off)
CH 2 VOLTS/DIV 5 mV
|. Repeat the complete Bandwidth check procedure for Channel 2.
17. CH 3 and CH 4 Vertical Bandwidth .
a. Set:
Vertical MODE CH 3 (CH 2 off)
CH 3 and CH 4 VOLTS/DIV O.1V
b. Connect leveled sine-wave generator (SG 503) output to the CH 3
Input via a 50 1 precision BNC coaxlal cable and a 50 2 BNC
termination.
c. Set the generator output for a six-division signal display at 50 kHz.
d.
Set
the
generator
