RF Filter Design Software (LC Ladder Networks) Iowa Hills Software Digital and Analog Filters RF Filter Design This free RF Filter program specializes in the design of LC band pass filters, but it also synthesizes low pass, high pass, and notch filters. Designing a band pass LC filter is almost a lost art today as most of these filters are built with ceramic resonators, and for the obvious reason, size. There are however, many relatively low volume applications not serviced by the ceramics houses that need these filters. RF filter design requires that you be very good with a simulator, network analyzer, and layout tools. This software will help do the easy part, which is, coming up with a good starting point for your simulator and optimizer. There are 4 basic ways to build an LC band pass filter.

Check out some screenshots from RFSim99 below. Yes, it works on Windows 10! Some RFSim99 issues and workarounds, courtesy of ZS6GST i) RFSim99 has a fuse that blows when setting the scale of Smith charts to ‘0’! When this happens the input screen is obsoleted and you have to start afresh. Solution; save often and take care never to set the Smith Chart scale to ‘0’. Ii) When sweeping a transmission line between 50 Ohm ports, the display will sometimes go crazy.

What is Spectrum Analyzer Software? A spectrum analysis is a computer application that is designed to make an analysis of the various elements of a radio frequency or RF in short. With the use of the software’s in this category, the users are able to make visualization with the use of various methods such as charts.

The beauty of this design method lies in the fact that these tank inductor values are chosen, not predetermined. This is incredibly important because it allows you to minimize the filter's insertion loss and use part values that inductor vendors have available. RF Filter Screen Shot Available on the.

Touchstone) is used to provide enhanced functionality and data analysis. The connection is made using a mini USB cable. (NOTE: A high quality USB cable should be used in order to limit EMC interference from the PC that could influence your measurements.) Documentation Documentation for Touchstone can be found.

After attaching the RF Explorer device to your Windows PC via USB cable then run this tool to update it with the firmware that was downloaded in step (3). (6) You should now be able to run the PC Client software for Windows that you downloaded in step (4).

Topographic Map (Touchstone Pro-only) The 'Topographic Map' chart shows accumulated RF energy as a function of frequency. The power of the signal strength in dBm is shown across the frequency span. A signal strength with a relatively low occurrence is 'blueish' in color, whereas increasingly brighter colors are used for signal strengths that occur more frequently. Signal strengths that occur most often are 'redish' in color. Over time, this spectral view will approximate the steady-state RF energy signature of a given environment.

Software download windows 10. Move onto Step 3. Right-click on 'USB Serial Port' and click on 'Properties' — as per below pic: Then: • Click: Port Settings • Click: Advanced • For 'COM Port Number' — you MUST choose any number between 1-4. If the COM port number is above 4, then we'll have to change it so it's between 1-4.

Over time, this spectral view will approximate the steady-state RF energy signature of a given environment. Delta Trace (Touchstone Pro-only) The 'Delta Trace' view can be used to view small (or large) changes in the RF spectrum over time. Here's how it works. When scanning begins the first trace is saved as a 'snapshot'. For all subsequent scans, the snapshot trace is subtracted from the current trace and the difference, i.e. 'delta', is displayed.
