POWER UP
To perform remote operation, you will need to connect the Analyzer to your PC via a serial
interface cable. You have the option to assemble a cable yourself or purchase one of the serial
interface cables, displayed below, directly from AEA.
The Analyzer can be powered up manually, using the ON key, or remotely, using your PC. To
remotely power up the Analyzer, simply send the letter "K" until you receive a "?" in response. At
this point, you can begin sending commands. When the Analyzer is already powered on, it will
automatically time out after a five-minute idle period in order to conserve batteries. It will power
back up when it detects an incoming serial stream.
RULES FOR COMMANDS
All commands must be in upper case letters. Lower case letters are invalid
u
All incoming commands to the Analyzer must be terminated with the letter "K". If the Analyzer
u
detects an incoming stream containing ten or more characters, that is not terminated with the
letter "K", it will output a "?" and discard the characters. (All commands contain fewer than ten
characters.)
All outgoing responses from the Analyzer are terminated with either a "K" or a "?". The letter
u
"K" indicates that the incoming command was properly executed and that no further
information is outgoing. The "?" indicates that the Analyzer did not understand the incoming
command. Re-enter the proper command.
The analyzer will accept commands manually entered on its keypad or remotely transmitted
u
from a terminal (serial commands). Do not attempt to use both methods at the same time. The
Analyzer will not accurately respond to mixed manual and serial commands.
COMMANDS
The following serial commands direct the Analyzer to perform certain functions. Remember, each
of these commands must be terminated with a "K" (as shown).
SK Send 100 SWR data points
ZK Send 100 Z (Impedance Magnitude) data points
XK Send 100 X (Reactance) data points
RK Send 100 R (Resistance) data points
