Note
Connect the signal generator's 10 MHz frequency reference output to the
4352B EXT REF Input on the rear panel as shown in Figure 2-4. With this
conguration, both the signal generators and the 4352B are phased locked to
the same reference frequency to obtain a stable measurement.

7. Set the signal generator output frequency to 10 MHz, and turn the signal generator output
ON.
8. A djust the signal generator output level around 6 dBm until the power meter reading is -10
dBm 60.1 dB .
9. Read the 4352B measurement result, and calculate the following formula:
T est Result (dB) = 4352B reading - (P ower Meter reading - Track(10M))
Record the calculated test result on the P erformance T est Record.
