Status Discontinued

The 89431A downconverter is an RF section for the 89441A signal analyzer. (It is also a tuner for other instruments.)

The 89431A can convert an 89410A DC - 10 MHz vector signal analzer to an 89441A DC - 2650 MHz vector signal analyzer.

The 89431A can be controlled externally as a stand-alone instrument through its EIA-564 port (same as RS-232 but with a 9-pin sub-D connector). The EIA-564 port is on the rear panel (Serial 2).

  • Frequency range: 2 MHz to 2650 MHz
  • Center frequency tuning resolution: 1.171875
  • IF bandwidth: 8 MHz
  • Input amplitude range: -50 dBm to +25 dBm
  • Maximum safe input power
    • Average continous power: +25 dBm (300 mW)
    • DC voltage: 25 V
  • Input channel (one)
    • VSWR
      Range ≥–20 dBm: 1.6:1 (12.7 dB return loss)
      Range ≤–25 dBm: 1.8:1 (11 dB return loss)
    • Impedance: 50 Ω
    • Connector: Type-N
  • Dynamic range
    • Harmonic distortion (with a single full scale signal at the input):
      ≥–25 dBm range: <–75 dBc
      ≤–30 dBm range: <–54 dBc
    • Third-order intermodulation distortion (with two input tones at 6 dB below full scale and ≥10 MHz): <–78 dBc
    • Third-order intercept (TOI) (with two input tones at 6 dB below full scale and ≥10 MHz): ≥33 dB above range
