h. Push the -more- bezel button.
i. Push the Amplitude bezel button (it will turn dark when activated) and
use the numeric keypad or general purpose knob to set the amplitude to
+4.0 dBm.
j. Check that the Channel On/Off front panel button LED is lit.
If it is not lit, then the channel output is off. Push the Channel On/Off
button to turn it on.
3. Set the frequency of the power meter to 100 kHz, and compensate the power
meter so that the reading value at 100 kHz may become 0 dB with the
frequency dependent offset function. Then set up the power meter to the
relative measurement mode.
4. Change the frequency of the power meter setting to 5 MHz so that it is the
same as the arbitrary function generator frequency.
5. The power meter shows the value difference from the reference value, which is
± 0.30. Set this value to the Flatness field of the arbitrary function generator.
6. Repeat steps 4 through 5 until the setting of the arbitrary function generator
is 20 MHz.
The output signal frequency of the arbitrary function generator increases in
5 MHz steps every time you increase the frequency. Set the frequency of the
power meter to the same frequency of the arbitrary function generator in step 4.
