Performance Check Procedure
12. Check lnput Sensitivity:
X I Attenuation, DC
and AC coupled; 1 MJZ, <70 mV p-p at G200 MHz
-
Refer to Fig. 4-5, performance check setup. Use the fol-
lowing control settings.
Sinewave Generator
Frequency Range 100-250
Frequency Variable 200
Amplitude Multiplier X 1
Output Amplitude 0.70

a. Remove the DC 5010 CHANNEL B input connection
and insert a 50 Q termination to the coaxial cable. Recon-
nect this cable to the CHANNEL B input.
b. Press the DC 501 0 AUTO TRlG button, LEVEL CH B
button, and the DISPLAY-TEST button.
c. Press the DC 5010 AUTO TRlG button, LEVEL CH B
button, and the DISPLAY-TEST button.
c. Press the DC 501 0

ton to adjust the trigger level for a stable display readout.
e. CHECK-that the DC 5010 display readout indicates
approximately 200.00XXX (the last three digits can vary due
to source instability).
f. Press to light the DC 5010 FREQ A button.
d. CHECK-that the DC 5010 display readout indicates
approximately 300.00XXX (the last three digits can vary due
to source instability).
e. Remove the 1 MHz frequency standard from the
DC 5010 CHANNEL A input.
f. Move the DC 5010 CHANNEL B input connection to
