VSA Modulation Parameters Setup Dialog
The VSA Modulation Parameters dialog allows you to specify the modulation setting for your measurement.
| Modulation Settings: | |
| Format: | |
| BPSK: Binary Phase Shift Keying | |
| QPSK: Quadrature Phase Shift Keying (default) | |
| Pi4QPSK: Pi/4 Quadrature Phase Shift Keying | |
| 8PSK: Octet Phase Shift Keying | |
| 3Pi8PSK: 3Pi/8 Phase Shift Keying | |
Modulation Tab | 16QAM: 16 Value Quadrature Amplitude Modulation | |
32QAM: 32 Value Quadrature Amplitude Modulation | ||

| 64QAM: 64 Value Quadrature Amplitude Modulation | |
| 128QAM: 128 Value Quadrature Amplitude Modulation | |
| 256QAM: 256 Value Quadrature Amplitude Modulation | |
| Symbol Rate: Sets the symbol rate for the | |
| measurement. | |
| Range: 10 kHz to 20 MHz | |
| Default: 3.84 MHz. | |
| Capture Time: Sets the length of the time during which | |
| samples are captured. | |
| Range: 1s to 5 µs* | |
| Terminators: us, ms, s, ks, Cancel | |
| * Constrained by the following: | |
| 10,000 ≥ (Symbol Rate x Capture Time ≥ 100 | |
| Filtering: | |
| Filter Type: Selects from the following receiver filters: | |
| Low Pass | |
| Nyquist | |
| Root Nyquist (default) | |
| Rolloff Factor: Sets the | |
| measurement. | |
| Range: 0.1 to 1.0 in steps of 0.01 | |
| Default: 0.22. | |
