The SIGLENT SHA850A series is a powerful and flexible handheld portable device that combines the functions of a spectrum analyzer, cable-and-antenna analyzer, and, optionally, a vector network analyzer. It is specifically designed for field and outdoor RF applications, providing reliable and efficient measurement solutions.
Product Overview
- This series offers a wide range of capabilities. In spectrum analyzer mode, it comes with a built-in amplifier and an independent signal source. With a fast scanning speed and high sensitivity, it can perform functions such as broadcast monitoring, channel power scanning, wireless interference location, power monitoring, and electromagnetic compatibility testing.
- As a cable and antenna tester, it includes a built-in DC voltage bias and has a 1-path-2-port vector network analysis function. This enables measurements like TDR (Time Domain Reflectometry), VSWR (Voltage Standing Wave Ratio), port matching debugging, insertion loss measurement, tower amplifier debugging, cable fault location, and Smith chart analysis.
Key Features
- Frequency Range
- For the spectrum analyzer function, the SHA851A covers a frequency range from 9 kHz up to 3.6 GHz, while the SHA852A extends it to 7.5 GHz.
- In cable and antenna test mode, the frequency range is from 100 kHz up to 7.5 GHz. The vector network analyzer (optional) also has a frequency range from 100 kHz up to 7.5 GHz.
- Noise and Phase Noise Performance
- It has a displayed average noise level (DANL) of -165 dBm/Hz (Typ.), ensuring accurate measurements even in low-signal environments.
- The single-sideband (SSB) phase noise is -104 dBc/Hz at 1 GHz with a 10 kHz offset (Typ.), contributing to high-precision frequency measurements.
- Additional Features
- A standard preamplifier is included, enhancing the device’s sensitivity. There is also an option for a full bandwidth source.
- Optional analog and digital signal modulation analysis modes are available for in-depth signal analysis.
- An advanced measurement kit with a waterfall chart (optional) provides a comprehensive view of signal characteristics over time.
- The device can be equipped with a GPS receiver and GPS logging functionality (optional), which is useful for applications where location data is required, such as in wireless interference mapping.
- User Interface and Portability
- It features an 8.4-inch multi-touch screen, allowing for easy operation and intuitive interaction.
- With a net weight of 3.2 kg, it is relatively lightweight for field use. The typical working time is 4 hours, making it suitable for extended outdoor measurements without frequent recharging.
