3. Set the synthesizer operating modes as follows:
FREQ: 1Hz
AMPTD: 5V p-p
OFFSET: 0V
MODE: CONT
FCTN: sine
4. Restore Model 2002 factory defaults, as explained in
paragraph 1.7.
5. Set maximum signal level to 10V as follows:
A. Press CONFIG then FREQ.
B. Select MAX-SIGNAL-LEVEL, then press ENTER.
C. Choose 10V, then press ENTER.
D. Press EXIT to return to normal display.
6. Press the FREQ key to select the frequency function.
7. Verify that the Model 2002 frequency reading is within
the limits shown in the first line of Table 1-10.
8. Set the synthesizer to each of the frequencies listed in
Table 1-10, and verify that the Model 2002 frequency
reading is within the required limits.
