Siglent SVA1015X 1.5 GHz Spectrum and Vector Analyzer

SVA1015X is a Siglent combined spectrum analyzer and vector network analyzer. It covers 9 kHz to 1.5 GHz as a spectrum analyzer and 100 kHz to 1.5 GHz as a vector network analyzer measuring S11 and S21, with a standard tracking generator, a standard preamplifier and a 10.1 inch multi-touch screen.

Spectrum analysis and S-parameter measurement in one box

The SVA1000X series adds a vector network analyzer mode to a spectrum analyzer platform. In spectrum mode the SVA1015X offers a resolution bandwidth of 1 Hz to 1 MHz, a typical displayed average noise level of -156 dBm/Hz and total amplitude accuracy below 1.2 dB. In network analyzer mode it measures vector S11 and S21 with a typical dynamic range of 60 dB from 100 kHz to 10 MHz and 80 dB from 10 MHz to 1.5 GHz.

The vector network analyzer mode displays Lin Mag, Log Mag, phase, group delay, SWR, Smith chart and polar chart formats, with 101 to 10001 sweep points, four traces and (6 + reference) markers per trace. Full one-port (OSL), response and enhanced response calibration are supported, with mechanical calibration kit definitions such as F503ME, F504MS and the 85032B/E.

Key features as printed in the datasheet

• Port 1 stimulus power -20 to 0 dBm and IF bandwidth of 10 kHz for network measurements.
• Directivity after calibration above 40 dB and trace noise of 0.1 dB.
• Optional distance-to-fault locator for cable and antenna testing based on time-domain analysis.
• Optional EMI mode with CISPR 16-1-1 filter and quasi-peak detector, plus advanced measurement and modulation kits.
• Web browser remote control from a PC or mobile device, with file operation.

Interface and mechanical

SVA1015X, SVA1032X and SVA1075X

The SVA1000X family has three frequency options: SVA1015X (1.5 GHz), SVA1032X (3.2 GHz) and SVA1075X (7.5 GHz). Choose the SVA1015X for filter, cable, antenna and VHF/UHF work below 1.5 GHz. Options listed in the ordering table are the advanced measurement kit SVA1000X-AMK, distance-to-fault locator SVA1000X-DTF, EMI mode SVA1000X-EMI, and digital and analog modulation analysis SVA1000X-DMA and SVA1000X-AMA. N-type and 3.5 mm economic (DC to 4.5 GHz) and standard (DC to 9 GHz) calibration kits are listed separately. Standard accessories are a quick start guide, USB cable and power cord.

Calibration and measurement practice

Calibrate the network analyzer at the cable or fixture plane with open, short and load standards before measuring S11, and use a through connection for S21 response calibration. Set the stimulus power low enough to avoid overdriving an amplifier under test, and keep any signal at the spectrum input below the 30 dBm average limit with the attenuator set above 20 dB. Never apply more than 50 VDC. Allow warm-up before critical readings and remember the specified operating range of 0 to 40 °C.

Antenna, cable and filter testing

Typical uses include antenna return-loss and SWR checks, cable fault location with the distance-to-fault option, filter and amplifier gain measurements, EMI pre-compliance and site surveys. For telecom and broadcast installers in GCC countries, the combined instrument avoids carrying two separate units. The datasheet lists applications such as broadcast monitoring, S-parameter measurement and education.

Selection and installation notes

Test and measurement instruments are selected from the accuracy, the range and the interfaces the work needs. Allow the warm-up time, use leads and probes rated for the voltage and category of the circuit, keep the inputs inside the stated limits and keep the calibration current according to your quality system. Record the settings used for any test that must be repeated later.
