Specifications for PA2500B Spectrum Analyzer

The model PA2500-B has the same specifications as the PA2500 with the following exceptions:

  • 20 dB Internal attenuator Standard, 50 dB is optional ($300)
  • Frequency response is flattened only between 1 and 1100 Mhz. Coverage is same, 0.1 to 1300 Mhz.
  • Absolute power accuracy for PA2500B is +/- 2.8 dB (1-1100MHz) as opposed to +/- 2.0 dB This is due to slightly less calibration effort, not hardware.
  • Only the audio jack is brought out on rear panel.
  • 300KHZ, 100KHZ and 3 KHZ RBW's are standard as in the model PA2500. The 15KHz and 500Hz filters are optional. The 15Khz RBW filter option is $250.
  • Highband (option 1), is not available with the PA2500B
