Monitor Outputs
There are two monitor outputs provided on the rear panel of the
ATS-1 Access. These connectors provide monitor outputs of the signal
at the INPUT and after processing for the READING.
The INPUT monitor normally outputs a near-constant-amplitude
duplicate of the signal on the input. In Analog Analyzer mode, the
output will be a buffered version of the signal at the input to the
Analog Analyzer.
The ANALYZER monitor normally outputs the signal after all filtering
and processing, immediately before being detected by the final reading
meter. In Analog Analyzer mode, the output will come from the
Analog Analyzer reading.
These signals vary significantly depending on the measurement
function. See the block diagram of the measurement, at the beginning
of each measurement function section in the Operation chapter. Each
block diagram shows the points in the signal path from which the
monitors are taken.
Printer Connector
The ATS-1 Access is equipped with a parallel printer port for
connection to a printer. The printer can then be used to print
hi-resolution graphs or numerical data from a sweep, and any screen
data may be captured and printed.
Most laser, ink-jet, and dot matrix printers are supported.
The printer connector is a female DB-25. Most printers are sold with
an interface cable with this type of connector.
If your printer is not equipped with an interface cable that can connect
directly to the parallel port, it probably has either a male DB-25
connector or a Centronics connector on it. An adapter cable must be
obtained to connect the printer to the ATS-1 Access. These adapter
cables are very standard and are available from any store that sells
computer accessories.
