1-19. The 8443A Tracking Generator/Counter is a

companion instrument to the 8553B/8552 Spectrum

Analyzer. The tracking generator provides a CW signal

that precisely tracks the analyzer's tuning frequency.

The signal's amplitude is calibrated and can be set, in

0.1 dB increments, from +10 dBm to less than -120

dBm. The counter section of the 8443A applies a

marker to the analyzer's CRT and counts the frequency

at the marker. The marker can be positioned to

measure the frequency, within 10 Hz, of any signal

being displayed. The 8443B Tracking Generator is the

tracking-generator-only version of the 8443A.
