Table 1-2. Supplemental Performance Characteristics

These supplemental Performance Characteristics expand the 8553B/8552B Specifications, describe the instrument's

unique features and characteristics, and provide other information useful in applying the instrument.

FREQUENCY CHARACTERISTICS

Frequency Range: For operation of the analyzer

outside the 1 kHz to 110 MHz range, see Figure 1-4.

Average Noise Level vs. Input Frequency Curve.

Scan Width:

Preset 0 100 MHz: Inverted marker identifies the

frequency that becomes the center frequency

for SCAN WIDTH PER DIVISION and ZERO

scan modes.

Zero: Analyzer becomes fixed-tuned receiver with

frequency set by FREQUENCY and FINE TUNE

Figure 1-3. Typical Resolution

controls and selectable bandwidths set by

BANDWIDTH control. Amplitude variations are

displayed vs. time on the CRT.

Resolution: See Figure 1-3 for curves of typical

8553B/8552B Spectrum Analyzer resolution using

different IF bandwidths.

Stability: First local oscillator can be automatically

stabilized (phase-locked) to internal reference for

scan widths of 20 kHz/div or less. Signal display

shift with stabilization <10 kHz.

Long Term Drift: (At fixed center frequency, after

1 hr. warmup).

Stabilized: 100 Hz/10 min.

Unstabilized: 5 kHz/min; 20 kHz/10 min.

Temperature Drift:

Stabilized: 200 Hz/°C

Unstabilized: 10 kHz/°C.
