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
2-4 (a).
3. Set the output frequency of the signal generator to 50 MHz and the amplitude to -10 dBm.
4. Measure the output amplitude of the signal generator using the power meter and record the
measurement result as reference value 1.
5. Modify the output frequency of the signal generator according to Table 2-3
Table 2-3 Output frequency of the Signal Generator
Frequency Amplitude Frequency Amplitude Frequency Amplitude
10 MHz 500 MHz 2.0 GHz
50 MHz 1GHz 2.5 GHz
100 MHz 1.5 GHz 2.999995 GHz
6. Modify the frequency of the power meter accordingly, measure the amplitude A1 and record the
measurement result each time the output frequency of the signal generator is modified; subtract
reference value 1 from A1 to calculate the system error.
7. Disconnect the signal generator and power sensor and synchronize the signal generator and
spectrum analyzer.
8. Connect the output terminal of the signal generator with the RF input terminal of the spectrum
analyzer using dual-N cable as shown in Figure 2-4 (b).
9. Set the output frequency of the signal generator to 50 MHz and the amplitude to -10 dBm.
10. Configure the spectrum analyzer:
a) Select external reference source.
b) Set the center frequency to 50 MHz.
c) Set the span to 10 kHz.
d) Set the reference level to 0 dBm.
e) Set the input attenuation to 10 dB.
