3. Prepare for the test:
a. Hook up the instruments: Connect the signal generator output through a
50 Ω N-N coaxial cable to the RSA3303A/RSA3308A INPUT. See
Figure 4- -12.

b. Initialize the analyzer:
H Press the SYSTEM key on the front panel.
H Press the Reset All to Factory Defaults side key.
c. Modify the default settings:
H Press the FREQUENCY/CHANNEL key on the front panel.
H With the Center Freq side key, set the frequency to 10 MHz using
the numeric keypad.
H Press the SPAN key on the front panel.
H With the Span side key, set the span to 10 MHz using the general
purpose knob.
4. Check the amplitude:
a. Press the PEAK key on the front panel to place the marker on the
signal peak.
b. Check that the marker readout is within - -10 dBm 0.3 dB.
5. Disconnect the hookup: Disconnect the cable at the analyzer input.
