- Revision History
-
- Version 3.00 - 11/01/93
- Added Transient analysis calculations. Added transmission
- lines as circuit elements. Added zoom and print features to
- plot screen. Added support for HP DeskJets. Improved
- support for HP LaserJet Series I. Now displays more digits
- of frequency when plotting narrow band high frequency
- graphs. Analysis routine is now 40-100% faster.
-
- Version 2.10a - 8/18/93
- In certain rare situations, graphs would autoscale improperly.
- Fixed.
-
- Version 2.10 - 11/09/92
- Now handles circuits with up to 90 nodes. Added option to
- print only circuit description and graphs. Negative
- inductor values are now accepted. Changed listing format
- for frequencies of 10 GHz and above. Added network (LAN)
- support. Fixed "border flash" when switching from graphics
- to text mode on some CGA cards. Added table of contents to
- manual.
-
- Version 2.01 - 2/03/92
- Improved syntax checking on the circuit description files.
- More input errors are spotted and flagged.
-
- Version 2.00 - 10/14/91
- Added group delay, impedance, VSWR and return loss
- calculations. Now has full support for 24 pin printers.
- Now supports HP LaserJet. Editor has been enhanced.
- Analysis routine is now twice as fast as previous versions.
- Added AT&T and MCGA support. Added support for a math
- coprocessor. European format for element values now
- accepted. Improved error checking on circuit description
- files. International time and date on printouts now
- supported. Numbers are now stored in IEEE binary format.
- No longer supports "non-compatible" video. Now requires
- 384K of system memory.
-
- Version 1.11 - 11/23/90
- Added the filename to the headers and plot sheet of the
- printout. Negative resistance values are now accepted.
- Fixed bug in hard copy plotting routine - plot would display
- spurious points if the plot exceeded the maximum range.
- Fixed bug in analysis routine; Occasionally, a circuit with
- a very wide range of reactive component values could create
- an internal numeric overflow.
-
- Version 1.10 - 9/14/90
- Added the option of 35 sample points to the select number of
- sample points menu. Greatly increased the number of plot
- ranges available when displaying results. Magnitude now
- spans .1 db/div to 80 db/div and Phase now spans 22.5
- degrees/div to 720 degrees/div.
-
- Version 1.02 - 1/30/90
- First release widely distributed.
