Promotion! If you buy a Siglent SSA3000X PLUS spectrum analyser in combination with the Siglent SRF5030T EMI probes, you automatically receive the SSA3000XP-EMI option for free. Promotion valid until December 31st 2023.
The Siglent SSA3021X-PLUS spectrum analyser is the successor to the popular SSA3021X. The PLUS series is in many ways similar to its predecessor, only the PLUS series has a touchscreen display and tracking generator. There are also several options available for the PLUS series. The spectrum analyser has a bandwidth of 9 kHz to 2.1 GHz with a very small noise. The resolution of the measurement can be set to only 10 Hz, which makes it possible to measure very precisely.
The low noise is a unique property of this spectrum analyser. This limits the measurement error on smaller signals in particular. The given noise figure is only -161dBm/Hz. This is low enough to be unnoticeable in typical use. The standard Pre-amplifier allows for measurements to small signals, but can be disabled for a one-to-one image of the signal.
With the bandwidth up to 2.1 GHz common signals like GSM, that starts at 380 MHz is well within the range of this spectrum analyser. A useful property of these spectrum analysers is the ability to upgrade them with optional accessories. One of these options is ACPR or Adjacent Channel Power Ratio, which is an important property for antenna engineers. This is a requirement in wireless telecommunications as channels are not allowed to overlap each-other too much.
The large 10.1" WVGA display with 1024 by 600 pixels offers ample space for measurement data. The software supports up to 4 cursors simultaneously, which allows for easy data analysis.
Are you looking for an attenuator with various connectors for your spectrum analyser? Then this utility kit from Siglent is suitable for you. See here for more information.

EMI pre-compliance software | The EMI pre-compliance software provides Quasi-peak detector and EMI filters. These can be used to test whether equipment meets the requirements of the EMI regulations. | |
SRF5030T EMI probes | This near field probe set contains 3 magnetic field probes (20, 10 and 5 mm resolution) and 1 electric field probe (5 mm resolution) for pre-compliance testing of printed circuit boards. | |
Reflection measurements | In combination with the Tracking generator this option can be used to measure the reflection of antennas. | |
Advanced measuring kit | This kit offers measurements like "Channel power", "ACPR", "Time domain power", "Occupied bandwidth", "Third order intercept" and "Carrier to Noise Ratio". It extends the analyzers' measurement capabilities enormously. | |
Digital Modulation Analysis module | Digital modulate function for the Siglent SSA3000X-PLUS spectrum analyzers, including: ASK, FSK, MSK, xPSK and xQAM. | |
