Notes

The Hewlett Packard Tracking Generator 8444A provides a level, calibrated RF signal which is exactly the tuned frequency of the spectrum analyzer. This enables swept frequency tests such as frequency response and return loss measurements up to 1300 MHz. With an external counter the frequencies of unknown signals on points along a frequency response curve can be made.

  • Frequency range: 500 kHz to 1300 MHz
  • Dynamic range: > 90 dB
  • Frequency resolution: 1 kHz
  • Residual FM: < 100 Hz
  • Calibrated output: -11 dBm to 0 dBm
  • Frequency accuracy: +/- 10 kHz
  • Amplitude accuracy: +/- 1.5 dB

The HP Tracking Generator 8444A is designed to complement both the 8554B and 8555A Spectrum Analyzer RF Sections.

The Tracking Generator/Spectrum Analyzer functions as a system to perform frequency response measurements. The Tracking Generator converts the first and third local oscillator (LO) signals from the Spectrum Analyzer RF to a signal that tracks the frequency tuning of the RF Section. Option 058 is for use with HP180 HP8558B Spectrum Analyzer. It adds a 500 MHz 3rd LO circuit to the Tracking Generator as it is not available on the HP8558B. This 500 MHz signal is brought out on a separate BNC connector on the rear panel of the 8444A, directly above the THIRD LO INPUT BNC connector. When the 8444A is used with an 8558B/180 Spectrum Analyzer system, the two rear panel BNC connectors are interconnected with a short BNC cable. With the First LO from the 8558B plus its own 500 MHz LO signal, the 8444A can provide a 0.5 to 1300 MHz tracking signal for the 8554B Spectrum Analyzer system.

Option 059 extends the frequency range up to 1500 MHz.
