70904A Agilent Analyzer


The 70904A is a used analyzer from Agilent. Analyzers are key tools to test electronic equipment in the engineering, medical, automotive, and technological industries. Use analyzers for monitoring the performances of many different types of electronic devices. You may need analyzers for the measurement of components such as audio spectrums, voltages and currents, signals, and frequencies.

Additional Features:

  • 100 Hz to 2.9 GHz broadband input conversion
  • Input attenuator varies from 0 to 70 dB in 10 dB steps
  • Probe connection on the front panel

The Keysight Agilent HP 70904A RF section contains an input attenuator and a mixer. It provides the 100 Hz to 2.9 GHz broadband input conversion for the Keysight Agilent HP 71100C spectrum analyzer and Keysight Agilent HP 71401C light wave signal analyzer. The Keysight Agilent HP 70904A RF mixer converts the incoming RF signals to the intermediate frequency (IF) for further processing. The broadband, low noise mixer offers the performance needed to make high dynamic range measurements.

The input attenuator can be automatically coupled either to the reference level for mixer protection or to the highest mixer level to maximize dynamic range. The input attenuator varies from 0 to 70 dB in 10 dB steps. Option H25 has 5 dB step attenuators. If you need to probe your circuit, you can drive the probe using the connection available on the front panel. High impedance probes, such as the Keysight Agilent HP 41800A and 85024A, are available. A buffered LO output is available to drive tracking generators or other modules such as the external mixer interface module.
