RIGOL Chapter 2 Performance Verification Test
DSA1000A/DSA1000 Performance Verification Guide
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.
5. Disconnect the signal generator and the power meter. Connect the [10MHz OUT] terminal of
the signal generator with the [10MHz IN/OUT] terminal at the rear panel of the spectrum
analyzer using dual-BNC cable to synchronize the two instruments.
6. Connect the output terminal of the signal generator with the input terminal of the spectrum
analyzer using dual-N cable as shown in Figure 2-3 (b).
7. Configure the spectrum analyzer:
a) Select external reference source.
b) Set the center frequency to 50 MHz.
c) Set the span to 1 MHz.
d) Set the reference level to 0 dBm.
e) Set the input attenuation to 10 dB.
f) Set the resolution bandwidth to 10 kHz.
g) Set the sweep time to auto and the auto sweep time to accuracy.
h) Press Single and wait for the instrument to finish a sweep; press Peak to find the
maximum peak and record the result A2.
8. Absolute Amplitude Accuracy=A1－A2 and compare it with the specification.
