Performance Check Procedure

c. Superimpose CH 3 and CH 4 waveforms at the center graticule line.

d. CHECK—that the leading edges of the two waveforms have less than

0.1 horizontal division separation at the center graticule line.

e. Disconnect the test setup.

16. CH 1 and CH 2 Vertical Bandwidth

a. Set:

X10 MAG

VERTICAL MODE

SEC/DIV

CH 1 VOLTS/DIV

CH 1 and CH 2 Input COUPLING

TRIGGER SOURCE

Horizontal POSITION

Off

CH 1 (CH 3 and CH 4 off)

0.1 ms

5 mV

VERT

12 o’clock

b. Connect leveled sine-wave generator (SG 503) output to the CH 1 in

put via a 50 f l precision BNC coaxial cable and a 50 f l BNC termina

tion.

c. Set the leveled sine-wave Generator output for a six-division signal

amplitude at 50 kHz.

d. Set the generator Frequency Range and Frequency Variable controls

for a 90 MHz output signal.

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 through 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

I. Repeat the complete Bandwidth check procedure for Channel 2.
