Wherein,
is the measurement value of the multimeter.
5. Calibrate the power meter:
a) Connect the power sensor to the input terminal and [POWER REF]
terminal of the power meter respectively.
b) Press Zero/Cal Zero Cal. Turn on power reference after the
calibration finishes and observe whether the measurement value of the
power meter is a 0dBm, 50MHz signal.
c) Turn off power reference.
6. Disconnect DG800 and the multimeter. Connect the power sensor and the
channel output terminal (take CH1 as an example; the test method is also
applicable to CH2) of DG800 using a BNC (f)-N (m) adaptor, as shown in Figure
2-3.

7. Keep the output impedance of CH1 of DG800 at 50Ω. Set the output waveform
of CH1 as a sine waveform with 5MHz frequency and 1Vpp amplitude. Set the
frequency factor of the power meter to 5MHz, record the measurement value of
the power meter and judge whether “measurement value-P
ref
” is between
-0.1dB and +0.1dB.
8. Keep the output impedance of CH1 of DG800 at 50Ω. Set the output waveform
of CH1 as a sine waveform with 10MHz frequency and 1Vpp amplitude. Set the
frequency factor of the power meter to 10MHz, record the measurement value
of the power meter and judge whether “measurement value-P
ref
” is between
-0.2dB and +0.2dB.
9. Keep the output impedance of CH1 of DG800 at 50Ω. Set the output waveform
of CH1 as a sine waveform with 15MHz frequency and 1Vpp amplitude. Set the
frequency factor of the power meter to 15MHz, record the measurement value
of the power meter and judge whether “measurement value-P
ref
” is between
-0.2dB and +0.2dB.
