The HP 8553B is a spectrum analyzer RF section, which can be used with the 141T (140 Series) spectrum analyzer display section, the 8552A/B spectrum analyzer IF sections, and the 8443A tracking generator/counter.
The analyzer is a highly sensitive superheterodyne receiver with spectrum scanning capabilities up to 110 MHz. Output video from the receiver circuits is applied to the CRT in the display section. A signal or group of signals can be analyzed in the frequency domain. Input signals are plotted on the CRT as a function of amplitude versus frequency. The amplitiude of the CRT is calibrated in absolute units of power (dBm) or voltage (µV/mV), so absolute and relative measurements of both amplitude and frequency can be made.
Controls of the instruments are arranged for easy operation. For wide spectrum analysis, the operator can use a preset scan of 0 to 100 MHz. For more detailed study, the spectrum width can be progressively narrowed to .2 kHz, or the scanning capabilities can be eliminated altogether to use the 8553B as a fixed frequency receiver. A bandwidth of 300 kHz is automatically selected for preset scan operation. For variable scan and fixed frequency operation, narrower bandwidths can be selected by the operator.
