the multimeter.
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 DG1000Z 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 DG1000Z using a BNC (f)-N (m) adaptor, as shown in
Figure 2-3.

7. Keep the output impedance of CH1 of DG1000Z at 50Ω. Set the output
waveform of CH1 as a sine waveform with 5MHz frequency and 2.5Vpp
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 DG1000Z at 50Ω. Set the output
waveform of CH1 as a sine waveform with 10MHz frequency and 2.5Vpp
