The Siglent SSA spectrum analysers have a bandwidth of 9 kHz up to either 2.1 or 3.2 GHz with a very small noise. The resolution of the measurements is as small as 10 Hz which allows for very accurate measurements.
The low noise is a unique property of these analysers. 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 3.2 GHz common signals like Wifi or Bluetooth, that operate on the 2.4 GHz band, can be analysed. But for example 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.

Optionally the following features can be added to the feature-set of the devices.
Tracking Generator (FREE for a limited time)
This option adds a tracking generator to the device. This allows for easy frequency-response analysis. The tracking generator has the same frequency range that the analyser offers, and an output range between -20 and 0 dBm.
De EMI pre-compliance kit offers Quasi-peak detector and EMI filters. This offers the ability to test if devices meet EMI requirements.
In combination with the Tracking generator this option offers the ability to measure reflection properties of an antenna.
With measurements like "Channel power", "ACPR", "Time domain power", "Occupied bandwidth" and "Third order intercept", this optuion adds a lot of possibilities to the measurement set of the analysers.
