External Sweeps
External sweeps are a special type of sweep in which the ATS-1 Dual
Domain generator does not perform the stimulus changes – they come
directly from the device-under-test, usually from a test tape, test CD, or
remotely located sweep source.
The analyzer expects an externally-applied sinewave signal to change
either upwards or downwards in frequency or amplitude. The signal
may change in discrete steps or in a continuous ‘glide’. If a
gliding-frequency tone is used, it must change no faster than five
seconds per octave (50 seconds for a 20 Hz – 20 kHz sweep).
The ATS-1 Dual Domain will take readings from a number of points
during the sweep and plot them on the graph at the measured
amplitude or frequency.
Printing
The ATS-1 Dual Domain has the ability to print directly to a printer
connected to the external printer port located on the rear panel of the
instrument.
The ATS-1 Dual Domain can print a text output of the current settings
and readings, exact images (or ‘screen dumps’) of some screens, and
tabular, hi-resolution, or ‘screen dump’ printouts from sweep data.
The printer must be compatible with either the Epson/IBM
dot-matrix/ink jet standard or the PCL ink jet/laser jet standard.
Before doing any printing, the correct output format for your printer
must be selected. This selection takes place on the Setup panel. To
get to the Setup Panel, press the PANELS key until you see this screen:
The upper left soft key selects the type of printer output. The choices
are ‘IBM GRAPH’ and ‘PCL GRAPH’.
