1-3. Local Operation
Typical local operations include front panel connections to the Unit Under Test (UUT),
and then manual keystroke entries at the front panel to place the calibrator in the desired
output mode. The front panel layout facilitates hand movements from left to right, and
multiply and divide keys make it easy to step up or down at the press of a single key. The
backlit liquid crystal display is easy to read from many different viewing angles and
lighting conditions, and the large, easy-to-read keys are color-coded and provide tactile
feedback when they are pressed.
1-4. Remote Operation (RS-232)
The Calibrator has two rear-panel serial data RS-232 ports: SERIAL 1 FROM HOST,
and SERIAL 2 TO UUT (Figure 1-2). Each port is dedicated to serial data
communications for operating and controlling the 5820A during calibration procedures.
For complete information on remote operations, see Chapter 5 of the 5820A Operators
Manual.
The SERIAL 1 FROM HOST serial data port connects a host terminal or personal
computer to the 5820A. You have several choices for sending commands to the 5820A:
you can enter commands from a terminal (for example, using the Terminal accessory
from Windows using a PC), you can write your own programs using BASIC, or you can
run optional Windows-based software such as 5500/CAL or MET/CAL. The 5500/CAL
software includes more than 200 example procedures covering a wide range of test tools
the 5820A can calibrate. (See Chapter 6 for a discussion of the RS-232 commands.)
The SERIAL 2 TO UUT serial data port connects a UUT to a PC or terminal via the
5820A (see Figure 1-2). This “pass-through” configuration eliminates the requirement for
two COM ports at the PC or Terminal. A set of four commands control the operation of
the SERIAL 2 TO UUT serial port. See Chapter 6 for a discussion of the UUT
commands.
