Rear Panel Features and Connectors
Figure 2-3. 8703B Rear Panel
Figure 2-3 illustrates the features and connectors of the rear panel, described below. Requirements for
input signals to the rear panel connectors are provided in the specifications and characteristics chapter.
1. EXTERNAL MONITOR: VGA. VGA output connector provides analog red, green, and blue video signals
which can drive a VGA monitor.
2. GPIB connector. This allows you to connect the analyzer to an external controller, compatible
peripherals, and other instruments for an automated system. Refer to Chapter 7, “Options and
Accessories” for GPIB information, limitations, and configurations.
3. EXT ALC INPUT. This connector allows you to input an external signal for the automatic leveling
control (ALC).
4. PARALLEL interface. This connector allows the analyzer to output to a peripheral with a parallel input.
Also included, is a general purpose input/output (GPIO) bus that can control eight output bits and read
five input bits through test sequencing. Refer to Chapter 7, “Options and Accessories” for information
on configuring a peripheral. Also refer to “The GPIO Mode” in the “Operating Concepts” chapter of the
user’s guide.
5. RS-232 interface. This connector allows the analyzer to output to a peripheral with an RS-232 (serial)
input.
6. KEYBOARD input (mini-DIN). This connector allows you to connect an external keyboard. This
provides a more convenient means to enter a title for storage files, as well as substitute for the
analyzer's front panel keyboard.
