Active Directional Antennas for YSA-P400

The XDA-1000 and XDA-2000 combine directional reception, a switchable broadband amplifier, and real-time antenna attitude sensing for YSA-P400 spectrum analyzer field workflows. They support spectrum monitoring, signal search, interference localization, field-strength surveys, and coverage mapping from 500 MHz to 10 GHz or 20 GHz.

Use amplifier mode when additional active gain is appropriate for a lower-level signal. Manual bypass supports stronger-signal measurements and extends the practical measurement range of the antenna and connected analyzer combination.

Model Selection

Choose XDA-1000 for measurements through 10 GHz and its higher 20 dB typical amplifier gain. Choose XDA-2000 when the workflow requires coverage above 10 GHz. Above 12 GHz the XDA-2000 trades passive gain for reach, so budget link margin from the 12 GHz breakpoint rather than from its lower-band figure, and expect the narrower 15 GHz beamwidth to give a sharper bearing at the cost of a slower search.

Directional and Active Operation

Directional response helps the operator compare signal level as the antenna bearing changes. The integrated amplifier improves active sensitivity where appropriate, while bypass mode supports stronger signals. Gain, beamwidth, front-to-back ratio, VSWR, amplifier gain, and amplifier noise figure values remain model- and frequency-dependent where stated.

YSA-P400 Antenna Workflow

The YSA-P400 interface can display antenna connection status and bypass or amplifier mode. Model-specific amplifier-on and amplifier-off antenna-factor data supports correction-profile loading for field-strength conversion.

Pitch, roll, and heading can be shown together with spectrum amplitude and field-strength information. In mapping workflows, GNSS measurement position, received signal strength, and antenna attitude can be correlated for signal search, coverage analysis, and on-site interference investigation.

Engineering Overview

Connected to a YSA-P400 spectrum analyzer, the active directional antenna combines directional response with a switchable broadband amplifier to improve sensitivity when locating low-level RF sources. Bypass mode supports stronger signals and wider practical measurement range.

An integrated attitude and heading reference system reports azimuth, pitch, and roll in real time. The YSA-P400 measurement workflow can correlate pointing direction with spectrum amplitude, field strength, and position data for more efficient search and survey work.

  • Broad Frequency Coverage: Continuous operation from 500 MHz to 10 GHz or 20 GHz, depending on the selected model.
  • Directional Response: Typical passive gain up to 5 dBi supports source localization and directional field measurements.
  • Switchable Amplifier: A built-in broadband amplifier provides 20 dB or 16 dB typical gain with manual bypass.
