Digital Frequency Domain Analysis with D5000 Signal Analyzer Software
Fast Spectrum Analysis Up To 5GHz
- Frequency Range from 01 to 5 GHz
- Spectral Integral SNR Measurement: 10 times faster than measurements via analog spectrum analyzer2
- Frequency Domain Tests: overwrite, spectrum analysis, NLTS, partial erasure
- 8 million points FFT implemented in hardware with selectable resolution bandwidth from 1 MHz to 10 kHz
- Programmable Averaging Mode
- Supported in WITE32 as a standard feature with D5000

1 Actual lower frequency bound is limited by the RWA Analog Box bandwidth
2 With typical setup
D5000 Signal Analyzer Software allows for performing spectrum analysis much faster and in a wider frequency range comparing to standard SA-960 spectrum analyzer of RWA-2000 series.
D5000 spectrum analysis is performed by Fast Fourier Transform (FFT) of the read-back signal, as compared to SA-960 analog point-by-point measurements.
For example, Spectrum SNR test is executed 10 times faster compared with measurements through analog spectrum analyzer. Resolution bandwidth is programmable and can be as low as 10 kHz.
D5000 FFT and SA-960
The table below compares parameters of SA-960 and D5000 FFT:
| Spectrum Analyzer Model | Frequency Range |
Resolution Bandwidth |
| SA-960 | 0.5–960 MHz | 100 kHz (fixed) |
| D5000 FFT | 0 – 5GHz | 10 kHz – 1MHz (programmable) |
Typical Sweep Times
The table below compares spectral measurements performed in 500MHz band using SA-960 and D5000 FFT spectrum analyzers:
| Spectrum Analyzer Model | Resolution Bandwidth | Test Time |
| SA-960 | 100 kHz (fixed) | 56 sec |
| D5000 FFT | 100 kHz | 1.5 sec |
| D5000 FFT | 10 kHz | 1.9 sec |
SpiSNR test setup: 1…500 MHz sweep with 0.1 MHz step, no partial noise, no band erase, signal is defined by first harmonic.
