Informationen:
                                    The A-7550 Spectrum Analyzer is a microprocessor-control1ed
} superheterodyne unit which offers ease of operation, while
including the most needed features of a spectrum analyzer.
1-2 STANDARD FEATURES
The A-7550 Spectrum Analyzer covers a range from 100 kHz to
999.9999 MHz at levels of up to +30 dBm. Signal levels may
be directly read on the CRT in either dBm* dByW, dBV, dBmV
or dByV. Signals can be stored, recalled, plotted or used
for comparison purposes. Standard A-7 5 5 0 input impedance
is 50Ω. All operating parameters are set via keyboard
o pera ti on .
1-2-1 DISPLAY METHOD
The A-7550 display is fully digitized. A VRS™ (Vertical
Raster Scan) method is used to form the display. The display
has'390 horizontal discrete points and 480 vertical discrete
points. Full scan range is from 0 Hz to 1 GHz.
Users familiar with other spectrum analyzers may be used to
seeing the zero hertz marker displayed anywhere on the
display. On the A-7550, the zero hertz marker does not move
to the right of the left edge of the display. The
microprocessor does not allow a setting that would
theoretically allow a "negative11 frequency to the left of
the zero hertz marker. The user should note this
characteristic when becoming familiar with the A-7550.
