Informationen:
                                    The Panalyzor, Model SB-12b, is an automatic scanning
superheterodyne receiver which permits analysis and
identification of one or many radio- frequency signals at
one time. Each signal within the band being scanned is
displayed on a cathode-ray tube as one of a series of
inverted V’s or “pips”. The pip amplitude and position along
the calibrated horizontal axis are indicative of signal
level and frequency, respectively. A CW signal produces a
single pip. Modulated signals (AM, FM or pulsed) cause a
series of
pips which indicate sideband distribution and levels.
The Model SB-12b provides two modes of operation divided
into seven ranges.
The variable sweep width mode of operation provides a 0 -
100 KC variable sweep width for search and preliminary
analysis and a 0 - 2 KC variable sweep width with automatic
frequency controlled sweep for detailed analysis.
The pre-set mode of operation provides pre-set, narrow band,
sweep widths of 14 KC, 7 KC, 3.5 KC, 500 cps and 150 cps for
slow speed, highly resolved analysis. The 2 KC, 500 cps and
150 cps sweep widths are AFC stabilized.
The Model SB-12b provides visual means of examining the
effects of power supply fluctuations, thermal changes,
humidity, component variations, shock, vibration and load
changes upon frequency. Both magnitude and direction of
frequency drift are indicated. Parasitic oscillations which
normally may pass unnoticed can quickly be detected and
identified. Spurious modulation by subsonics, hum and noise
are readily spotted. In single sideband linearity tests, the
Model SB-12b permits in-band intermodulation distortion
readings to -60 db.
Because of its Panoramic presentation the instrument is
invaluable for monitoring a frequency band for the
appearance, disappearance and shift of signals. Highly
useful graphic displays of such phenomena as Bessel function
distributions of f-m signals, energy distribution of pulsed
r-f signals with low p.r.f.’s, a-m sidebands, etc., can be
obtained.
The SB-12b is unique in that it offers all the advantages of
automatically scanning spectrum presentations, yet enables
examination of signals so closely adjacent in frequency that
their corresponding deflections normally tend to merge
together or even completely mask one another even with
static wave analyzers. This instrument can, at reduced
sw’eep widths and slow sweep rates, resolve equal amplitude
signals down to 10 cps separation. Signals with an amplitude
ratio of 60 db separated by 60 cps are clearly separated.
