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 power meter is a 0
dBm, 50 MHz signal.
c) Disable Power Ref.
2. Connect the output terminal of the signal generator with the program-controlled attenuator;
then, connect the program-controlled attenuator with the power sensor, as shown in Figure 2-8
(a).
3. Set the output frequency of the signal generator to 50 MHz and the amplitude to +10 dBm.
4. Set the attenuation of the program-controlled attenuator to 40 dB and measure the amplitude
using the power meter. System Error Reference Value = Power Meter Measurement
Value - (+10 dBm - 40 dB) and record the calculation result in the test record form.
5. Modify the attenuation of the program-controlled attenuator according to the Test Record
Form (keep other parameters unchanged). Each time the attenuation is modified, measure the
amplitude using the power meter; System Error = Power Meter Measurement Value -
(+10 dBm - Attenuation of the Program-controlled Attenuator) - System Error
Reference Value and record the calculation result in the test record form.
6. Disconnect the program-controlled attenuator and the power sensor and connect the output of
the program-controlled attenuator to the RF input terminal of the spectrum analyzer.
7. Set the attenuation of the program-controlled attenuator to 40 dB.
8. Configure the spectrum analyzer:
a) Set the center frequency to 50 MHz.
b) Set the span to 10 kHz.
c) Set the reference level to -40 dBm.
d) Set the input attenuation to 10 dB.
e) Set the resolution bandwidth to 1 kHz and the video bandwidth to 10 Hz.
f) Set the sweep time to auto and the auto sweep time to accuracy.
9. Press Peak to find the maximum peak. Global Error Reference Value = Maximum Peak of
the Spectrum Analyzer - (+10 dBm - 40 dB) and record the calculation result in the test
record form.
10. Set the attenuation of the program-controlled attenuator, the reference level of the spectrum
