Frequently Asked Questions:

Question: Which DUTs can a VNA measure?

Answer: Typical DUTs (Devices under Test) for VNA (vector network analyzers) can be for example filters, where input/output impedance, insertion loss, frequency response, group delay, phase, stopband attenuation, etc. are of interest. For RF amplifiers, input/output impedance and frequency response also are measured, plus gain, 1-dB compression, and IP3 (Intercept Point 3, Third Order Intercept Point). For L and C (inductances and capacitances), the S-parameters are determined for simulations. Other typical DUTs for VNA are cables and antennas (impedances, matching, cable test, etc.), mixers and circulators, up to complete subsystems.

Question: Are the Siglent SVA1015X, SVA1032X and SVA1075X full VNA/vector network analyzers?

Answer: VNA are usually priced in much higher regions than the Siglent SVA1000X series instruments. Can they be "real" VNA then? Yes, the SVA1000X devices are "real" VNAs, but with limited features. They offer one fixed-power source and only one receiver. In addition, the dynamic range is about 80 dB as opposed to 100 dB for "full" VNAs. However, there are many applications where this is perfectly adequate and the extra cost of an expensive VNA would not be justified (see next question).

Question: What can be measured with the Siglent SVA1015X, SVA1032X and SVA1075X, what cannot be measured?

Answer: The Siglent SVA1000X series is suitable for measuring the S-parameters/scatter parameters S11/S21 (reflection/transmission), for example for measuring RF components such as filters, amplifiers, cables and antennas. The instruments also measure feedback attenuation/VSWR, insertion loss, phase change, group delay and complex impedance (impedance matching for RF designs).
Unlike "full" VNAs, they can measure the S-parameters S22/S12 only by turning the DUT and recalibration. The power level cannot be adjusted and sweeping of power and offset frequency sweep is not possible. Also, the instruments do not offer a multi-window view.

Question: Why do I need to calibrate the VNA?

Answer: An essential part of an accurate VNA measurement is calibration. Therefore, a VNA should always be purchased with an appropriate calibration kit (see accessories). A common calibration method is the SOLT method (also OSLT; short, open, load, and through). Calibration is performed before each measurement in a new measurement configuration. Calibration eliminates systematic errors in the measurement as far as possible, for example frequency and phase response in the measuring instrument, measurement setup, cables and accessories. These systematic errors are reproducible and always equally present. Therefore, they can be widely compensated by calibration. Additionally occurring random measurement deviations (e.g. noise) cannot be compensated but only statistically detected. Calibration kits are available for different frequency ranges and with different connection types such as N or SMA female/male.

Question: Do the Siglent SVA1015X, SVA1032X and SVA1075X have a touch screen?

Answer: Yes, all models are equipped with a 10.1"/25.6 cm multi-touch screen. USB Host and Device as well as Ethernet/LAN interfaces are standard. GPIB (IEEE488) can be upgraded via an optional USB-to-GPIB adaptor.
