Introduction
The SIGLENT SSA3000X and SVA1015X products are based on a similar swept superheterodyne spectrum analyzer platform and have very similar starting prices. There are quite a few similarities, but also a few differences that could affect the end results for particular applications.
The table below compares the major specifications and the comparable options as they pertain to specific applications like VSWR.
| SSA3000X | SVA1015X | |
| Spec An Frequency Range | 9 kHz – 2.1 GHz (3.2 GHz model available) | 9 kHz – 1.5 GHz |
| DANL | -161 dBm/Hz | -156 dBm/Hz |
| Min RBW | 1 Hz | 1 Hz |
| Total Amplitude Accuracy | +/- 0.7 dB | +/- 1.2 dB |
| Tracking Generator and Frequency Range | 100 kHz – Max Frequency | 5 MHz – Max Frequency |
| Demodulation | AM/FM demod with audio output (Free) | AM/FM demod with audio output (Free) |
| EMI Measurements | Option EMI-SSA3000X (FCC RBWs, QP detector, -6 dB EMI filter) | Option SVA1000X-EMI (FCC RBWs, QP detector, -6 dB EMI filter) |
| Broadcast Measurements | Option AMK-SSA3000X (Channel power, Adjacent channel power ratio, Time domain power, Occupied bandwidth, Third-order intercept, Spectrum monitor) | Option SVA1000X-AMK (Channel power, Adjacent channel power ratio, Time domain power, Occupied bandwidth, Third-order intercept, Spectrum monitor) |
| VSWR/Return Loss Measurement | Option Refl-SSA3000X (Includes on-screen return loss, reflection coefficient, and VSWR measurements displayed)
NOTE: Requires return loss bridge hardware* Currently has a 100 Hz minimum span |
Option SVA1000X-VNA (On screen S11 with SWR graph)
NOTE: Currently has a 5 MHz minimum span |
| Option RBSSA3000X (Includes on-screen VSWR measurement AND return loss bridge hardware) |
*Compatible with many commercially available return loss bridges/directional couplers
Additional SVA Features and Options
Still having trouble choosing?
