CIA-HF REMOTE SERIAL INTERFACE
A Windows95/98 color-graphics interface is now available for the Tempo Research CIA-HF* Complex Impedance Analyzer. This software includes a six foot
shielded serial communications cable for connection to a DB-9 COM port on your pentium computer. Longer cables are available. Developed in cooperation
with AEA, a division of Tempo Research.
Software Features:
Remote Controls: center frequency, sweep width, battery conservation mode ("sleep").
Graphics plots (all versus frequency) with user-defined colors:
resistance, reactance, SWR, impedance magnitude and phase, reflection-coefficient magnitude and phase, return loss.
Tables: all parameters in graphics plots at the CIA-HF input, and at the antenna (at the end of your transmission line).
Smith Chart: resistance and reactance sweep at the CIA-HF input, and at the antenna (at the end of your transmission line). User-defined curve colors.
Additional Features:
1) ability to save and read impedance data files on hard drive or floppy.
2) ability to measure transmission line velocity factor, electrical length and loss (necessary for determining impedance at antenna when transmission line is long).
3) automatic correction of REACTANCE SIGN.
4) real-time COM port selection.
5) serial communication testing built-in.
6) user manual on floppy disk in both DOC and WPD formats.
Recommended Minimum PC requirements:
32 MB RAM, 133 MHz pentium, Windows 95 or 98, floppy drive, hard drive with 20 MB of available space, spare serial port (COM1 thru COM4). A 17 inch
color monitor operating in 1024 by 768 pixel resolution, with 256 or more colors is suggested. Smaller monitors will also work as long as the video driver can
handle the required resolution. Lower resolution versions of the program are not available: 800 by 600, and 640 by 480.
