Introduction to Sceptre®
"We do circuits - thoroughly!"




FACT:
A frequency domain circuit analysis program should be one of the first programs in your CAD tool box. With our easy to use package you can quickly compute stability, gain/loss, VSWR, bandwidth, etc. on a wide variety of passive and active circuits. It has a built-in File Utility and a handy tweak mode that lets you try different component values on the fly.


QUESTION:
Why isn't our Sceptre program in your tool box? At only $29.50 its hard to beat! All prices are in USD, and for a single-user license. 

   
EXAMPLE:
Here is the equivalent AC circuit of a 100-1500 MHz amplifier designed by Ken Wyatt of Hewlett-Packard Co. Ken designed it using our MicroWorks Design Package. His in-depth review of our Sceptre program, and others in the MicroWorks package, entitled "Wideband design proves abilities of low-cost CAD," can be found in the November 1988 issue of Microwaves & RF magazine. To show you how easy Sceptre is to use, we've listed the circuit file down below the amplifier schematic, and then followed that with an analysis of the circuits performance.

Ken has used emitter and collector-to-base feedback to make the stability factor greater than one, to flatten gain,  and improve VSWR. His design article shows how to calculate all the component values.

OUTPUT TABULATION:
Here is an analysis of the amplifier by Sceptre. We have used the "S1" print option for overall network s-data and stability information. If the circuit were unstable, the "S2" option would give us the location of stability circles on the in/out plane. Also, by using the "IR" or "OR" options, we could see the input (or output) reflection coefficient, VSWR, R.L. (dB), and Z (R+jX) ohms.

EASE OF USE:

This program is menu driven and very simple to use. The User Manual is clearly written, (you can READ IT on-line), and tutorial in nature. It introduces the User to analysis in the frequency domain by using every day circuit examples. Sceptre can also write .IMP files for use by our SmithMatch match network design program!



MATERIAL INCLUDED:
The program, and its support files, can be downloaded, by you, direct from our server. The User Manual for Sceptre is available on-line. You can view it or print it out at your leisure. By having an on-line manual, you're assured that you will get any typo error corrections or tips instantly! Your manual will never be "out of date."
