Figure 2-3 Absolute Amplitude Accuracy Test Connection Diagram
Test Procedures
1. Calibrate the power meter:
a) Connect the power sensor with the [REF] terminal and Channel A of the power meter. Press
Channel and set the frequency of Channel A to 50 MHz.
b) Press Cal and enable Power Ref in the Zero/Cal menu. Press Zero+Cal and wait for the
calibration to finish; then, observe whether the measurement value of the power meter is a
0 dBm, 50 MHz signal.
c) Disable Power Ref.
2. Connect the output terminal of the signal generator with the power sensor, as shown in Figure
2-3 (a).
3. Set the signal generator to output a sine waveform with 50 MHz frequency and -10 dBm
amplitude.
4. Measure the output amplitude of the signal generator using the power meter; read and record
the measurement value A1 of the power meter.
