Page 10 of 19 Procedure #: CP1005 Revision: A
b. Connect the CFG253 MAIN OUTPUT to the input of a Frequency Counter.
Check the frequency reading for each set-up listed in Table 6:
Table 6
RANGE FREQ DIAL COUNTER READING
1 M 3.0 2.85 MHz - 3.15 MHz
1 M 0.3 150 KHz - 450 KHz *
100 K 3.0 285 KHz - 315 KHz
10 K 3.0 28.5KHz - 31.5KHz
1 K 3.0 2.85KHz - 3.15KHz
100 3.0 285 Hz - 315 Hz
10 3.0 28.5 Hz - 31.5 Hz
1 3.0 2.85 Hz - 3.15 Hz
* The Frequency reading accuracy is 5% of full scale. 5% of 3 MHz is 150
KHz
c. Disconnect cable from the Counter and CFG253.
